Logging into the web interface The Codian IP VCR web interface is used for administering the IP VCR device, managing recordings, users, and predefined endpoints. You can also perform many recording-related tasks using the web interface that you cannot otherwise do. When connecting to the Codian IP VCR web interface, you must log in so that the IP VCR can associate the session with your configured user and a set of access privileges.
Watching a recording from the IP VCR The IP VCR offers a variety of ways to watch stored recordings. These include watching recordings using an H.323 endpoint and watching recordings by web streaming. Watching recordings can be an interactive experience. The following pages provide detailed explanations of the options available. Refer to these for more information.
Using a video endpoint to watch recordings You may watch recordings stored on the IP VCR using an H.323 or SIP video endpoint. There are a number of ways to connect to the IP VCR; refer to the sections below for details of the options available to you: • • • Connecting directly using a phone number Connecting via the auto attendant Being called by the IP VCR Note that in the current release, HD recordings cannot be played back by an endpoint. Watching recordings is an interactive experience.
Entering a PIN If you connect to a protected recording, you will be presented with the PIN entry screen, and will hear audio prompts playing. Use your endpoint's numeric keypad to enter the PIN, followed by #. (Note that some endpoints require you to activate the keypad before dialing, for example by pressing the # key.
To skip quickly backwards though a recording (fast rewind): 1. Change the camera control to “far”. 2. Use the left control to engage rewind mode. The video will rapidly rewind, skipping several seconds backwards at a time, and the playback time will be shown in the corner of the screen. 3. When you reach the point from which you wish to resume playback, press either up to resume or down to pause playback as required. 4. If the start of the recording is reached, rewind will stop and playback will pause. 5.
Using an auto attendant Your system administrator may have set up an auto attendant for you to use to view stored recordings. An auto attendant presents you with a menu from which you can choose a recording to watch. For further information about watching and creating recordings, refer to the document "Watching Recordings", available in the Documentation area of the web site. Calling an auto attendant There are typically two ways to call an auto attendant using your video endpoint.
To exit DTMF navigation mode: • press the pound (hash) key twice as follows: ## The message "DTMF menu navigation disabled" appears briefly at the bottom of the auto attendant display. When in DTMF navigation mode, you will not be able to use the number keys to enter the numeric ID of a recording. Typically, you will have these options: Record this session This option enables you to record the video your endpoint is sending to the IP VCR.
Using streaming to view recordings The Codian IP VCR supports streaming, which involves sending recorded media (audio and video) to a remote computer, allowing the user to watch and listen to the recording. To view a recording using streaming: 1. Go to Recordings. 2. Click Watch next to a stored or in-progress recording. (Note that HD recordings cannot be streamed until the recording has completed and the video has been transcoded into streaming media.) 3.
Using the IP VCR to make a recording The IP VCR allows you to create recordings in a number of different ways. These include recording conferences on the MCU, recording single video endpoints non-interactively and via the recording console, and transparent recording of point-to-point calls with another endpoint. The following pages provide detailed explanations of the options available. Refer to these for more information.
Automatically recording a conference on a Codian MCU There are a number of different ways in which you can configure your IP VCR and MCU to record conferences that take place on the MCU.
Note that if you are intending to use this method frequently with the same folder, it will be quicker to configure the recording ID as an endpoint on the MCU. The procedure is the same as when you configure an H.323 endpoint on the MCU. For more information, on the MCU, go to Endpoints > Add H.323 endpoint and view the online help.
Non-interactive recording of an endpoint Depending on the configuration of the IP VCR, you may be able to make recordings non-interactively. That is, once connected to the IP VCR, recording takes place automatically, and with no feedback to the user. If you would prefer to have more feedback when making recordings, consider using the recording console (see Using the recording console).
6. Press Call endpoint or Call selected endpoint. 7. Answer the call on the video endpoint. Recording will start. Controlling the recording The nature of non-interactive recording is that the user has little or no control over recording. When you have finished recording, simply hang up the call to end and store the recording.
Using the recording console The recording console allows you to make recordings interactively. That is, it allows you to monitor the recording while it is in progress, to check that the view is as you require.
Status A status indication is displayed in the bottom left-hand corner of the recording console. It shows the current state of recording. When you first enter the recording console, the status indication will show paused. Recording length The length of the recording is shown in the bottom right-hand corner of the screen, as minutes and seconds. When you first enter the recording console, this will show a zero-length recording. The recording length will update in real-time as recording progresses.
Recording point-to-point calls The IP VCR is able to transparently record point-to-point calls. A point-to-point call is one where just two endpoints are involved - the traditional type of call. If you wish to record point-to-point calls, the gatekeeper settings of the IP VCR must be configured correctly (see Configuring gatekeeper settings). Instead of simply calling the other endpoint by dialing its E.164 number from your video endpoint, you must add a prefix that tells the H.
Calling out from the IP VCR As well as using your video endpoint to call into the IP VCR in order to make and watch recordings, you may also perform both of these functions using the IP VCR to call out to your endpoint.
Understanding the playback and recording parameters pages Whether calling out to play back or to record, you must specify which endpoint you wish to call. The Playback parameters and recording parameters pages are very similar. Refer to the table below for details: Field Field description Usage tips Playback parameters There are no playback-specific parameters. Recording parameters Name of recording to create Specify a name for the new recording.
• • strongly favor a resolution of at least 25 frames per second. Favor sharpness: the IP VCR will use the highest resolution that is appropriate for what is being viewed. Balanced: the IP VCR will select settings that balance resolution and frame rate (where the frame rate will not be less than 12 frames per second). Transmitted video resolutions Choose the setting for transmitted video resolutions Retain the default setting (use box-wide setting) from the IP VCR to this endpoint.
H.239 (content channel video) support The H.239 protocol allows the Codian IP VCR to support an additional video stream to or from each connected H.323 endpoint. Thus, there are potentially 3 media streams between each H.323 endpoint and the IP VCR: audio, main video and H.239 video. In general, the main video channel is used for motion video (i.e.
Creating customized MPEG and Windows Media Video format files The MPEG and WM Converter Tool is a tool that converts .codian files to MPEG-1 or Windows Media Video (.wmv) format. It is available from the Support area at www.codian.com. The MPEG and WM Converter Tool enables you to create MPEG videos or Windows Media videos that include up to two video streams and/or the content channel. The resulting encoded MPEG/'.

The possible states for each folder ID are: • • • • • • n/a This ID is not configured to be registered with a gatekeeper; because of this, there is no applicable registration status to show. Registering This ID is in the process of registering with the gatekeeper.
Storing recordings externally About external storage Any IP VCR folder (including the root) can be configured to link to an external Network File System (NFS) location. Recordings in a folder configured to link to an NFS location can either physically be stored on the IP VCR or in the NFS location.
H.323 gatekeeper registration of externally stored recordings Each IP VCR folder that links to an external location has a separate "Register external recordings with gatekeeper" setting. When this is selected, each external recording retains its own H.323 gatekeeper and SIP registration option.
Understanding the connections list The Connections list displays information about all recordings and playbacks currently in progress, as well as calls to the auto attendant. To view the Connections list, go to Connections. See the table below for an explanation of the fields that display: • • Active connections Connection controls Active connections An active connection refers to any call into or out of the IP VCR (whether to watch or make a recording), or a web streaming session.

imply potential network problems. Media information If the time stamps or marker bits (or both) are detected to be unreliable in the incoming video stream, information will be displayed here. This field is not displayed when there is no problem with the time stamps and marker bits. Where there is a problem the following text is displayed: "Media timestamps unreliable", "Media marker bits unreliable", or both if both conditions detected.
For example, if all participants in the conference were watching a single participant at full screen, no other participants' video streams would be needed at all. So the IP VCR would request that those streams were sent at a low bit rate in order to avoid needless use of network bandwidth. If the receive bit rate has been limited to below the maximum channel bit rate, the reason for this limitation can be seen by moving over the icon.
VCR to this endpoint. Frame rate The frame rate of the video stream currently being sent to the endpoint. Temporal/spatial A number that represents the tradeoff between video quality and frame rate. A smaller number implies that the IP VCR prioritizes sending quality video at the expense of a lower frame rate. A larger number implies that the IP VCR is prepared to send lower quality video at a higher frame rate.

Displaying the gateway list You can configure the Codian IP VCR to work with one or more H.323 gateways. The IP VCR can then effectively call through these configured gateways to one or more endpoints which are registered with the gateway but would not be reachable directly from the IP VCR. For example, an IP PBX could be configured as a gateway, and the IP VCR could then call its registered E.164 numbers. The gateway list shows all of the currently configured H.323 gateways.
Adding and updating gateways You can configure the Codian IP VCR with one or more H.323 gateways: • • To add an H.323 gateway, go to Gateways > Add new H.323 gateway. After entering the settings described below, click Add H.323 gateway. To update an existing H.323 gateway, go to Gateways and click on a gateway name. After updating the settings described below, click Update H.323 gateway. Field Field description Name The descriptive name of the gateway.
Displaying the built-in gatekeeper registration list The IP VCR contains a built-in gatekeeper with which devices can register multiple IDs. IDs can be numbers, H.323 IDs (e.g. Fredsendpoint) or prefixes. Up to 25 devices can be registered without a feature key. Feature keys can be purchased to increase this number. Note: The IP VCR can register with its own built-in gatekeeper. The IP VCR then counts as one registered device. See Configuring gatekeeper settings.

Configuring network settings To configure the network settings on the IP VCR and check the network status, go to Network > Port A or Network > Port B. The IP VCR has two Ethernet interfaces, Port A and Port B. The configuration pages for the two interfaces look and behave similarly, and so are described together. Differences will be noted as appropriate.
Secondary name server (DNS) Identifies an optional second name server. Domain name Specifies an optional suffix to add when performing This can allow you to use non-fully qualified host DNS lookups. names when referring to a device by host name (DNS suffix) instead of IP address. For example, if the domain name is set to codian.com, then a request to the name server to look up the IP address of host endpoint will actually lookup endpoint.codian.com.
Duplex Identifies the connection duplex mode: The duplex setting must match that of the device to which this port is connected. • Full duplex • Both devices can send data to each other at You only need to select this option if you have the same time chosen manual Ethernet settings, as described above.
Configuring IP routes settings If the Video Firewall feature is enabled (see Upgrading the firmware), you will need to set up one or more routing settings to control how IP traffic flows in and out of the IP VCR. It is important that these settings are configured correctly, or you may be unable to make calls to or from the IP VCR or access the web interface. To configure the route settings, go to Network > Routes.
Adding a new IP route To add a new route, first enter the details using the table below for reference. When you are satisfied with the details entered, click Add IP route to make the addition. If the route already exists, or aliases (overlaps) an existing route, you will be prompted to correct the problem and try again. Field IP address / mask length Field description Usage tips Use these fields to define the type of IP addresses to To route all IP addresses in the range 192.168.4.128 to 192.168.4.
If a manually configured route specifies Port B (for example) and that port is disabled, packets matching that route will not be automatically routed via Port A, but discarded. You should take care to avoid this situation. Current IP status This table shows the current default gateway and name server(s) for Ethernet Ports A and B. No fields can be changed, and are provided for reference when configuring the other parameters described in the sections above.
Configuring IP services To configure IP services, go to Network > Services. Use this page to control the type of services that may be accessed via Ethernet Ports A and B. You might use this if one Ethernet port is connected to a network outside your organization's firewall, and you wish to restrict the level of access that external users are entitled to, for example, by disabling FTP access via Port B. Refer to the table below for more details.
conference participants who are using H.323. If a port is disabled, this option will be unavailable. Incoming SIP Allows/rejects incoming calls to the IP VCR using SIP over TCP. (TCP) Disabling this option will not prevent outgoing calls to SIP devices being made by the IP VCR. That is, the IP VCR will need to dial out to conference participants who are using SIP over TCP. If a port is disabled, this option will be unavailable. Allows/disables streaming from the IP VCR to Streaming Windows Media Player.
SNMP on Port B. Note that by default SNMP Traps are sent to port UDP port 162 (on the destination network management station); this is configurable. For more information, refer to Configuring SNMP settings. H.323 gatekeeper Defines the ports for the H.323 gatekeeper. If a port is disabled, this option will be unavailable. You must use the same port number for both Port A and Port B. The number is automatically refreshed for Port B.
Configuring SNMP settings To configure monitoring using SNMP, go to Network > SNMP. The IP VCR sends out an SNMP trap when the device is shut down or started up. The SMNP page allows you to set various parameters; when you are satisfied with the settings, click Update SNMP settings. Note that: • • The 'system up time' that appears in the trap is the time since SNMP was initialized on the IP VCR (and therefore will differ from the Up time reported by the IP VCR on the Status > General page).
Trap receiver Enter the IP address or hostname for up to four addresses 1 to devices that will receive both the general and the authentication failure traps. 4 The traps that are sent by the IP VCR are all SNMP v1 traps. You can configure trap receivers or you can view the MIB using a MIB browser. You can set the UDP port number for the trap in the format : . By default the UDP port number is 162.
Configuring QoS settings To configure Quality of Service (QoS) on the IP VCR for audio and video, go to Network > QoS. QoS is a term that refers to a network's ability to customize the treatment of specific classes of data. For example, QoS can be used to prioritize audio transmissions and video transmissions over HTTP traffic. These settings affect all audio and video packets to H.323 and SIP endpoints, and to streaming viewers. All other packets will be sent with a QoS of 0.
• • • • • Bits 0-2 set IP precedence (the priority of the packet). Bit 3 sets delay: 0 = normal delay, 1 = low delay. Bit 4 sets throughput: 0 = normal throughput, 1 = high throughput. Bit 5 sets reliability: 0 = normal reliability, 1 = high reliability. Bits 6-7 are reserved for future use and cannot be set using the IP VCR interface. You need to create a balance by assigning priority to audio and video packets whilst not causing undue delay to other packets on the network.
Displaying and resetting system time The system date and time for the IP VCR can be set manually or using the Network Time Protocol (NTP). To configure Time settings, go to Settings > Time. System time The current system date and time is displayed. If you do not have NTP enabled and need to update the system date and/or time manually, type the new values and click Change system time. NTP The IP VCR supports the NTP protocol.
Configuring encryption settings You can configure the IP VCR to record encrypted conferences on an MCU and encrypted calls from H.323 endpoints, and to encrypt the connection when playing back a recording to an H.323 endpoint.
Configuring global connection settings You can modify the global connection settings for the IP VCR choosing by Settings > Connections. However, many of these values can be overwritten by other IP VCR or endpoint settings. • • Connection settings Advanced settings Connection settings Refer to this table for assistance configuring the connection settings. After making any configuration changes, click Apply changes.

Configuring gatekeeper settings To configure gatekeeper settings, go to Settings > Gatekeeper. You can configure the IP VCR to use a gatekeeper, which can make it easier for end-users to watch and make recordings using directory numbers rather than requiring them to know the IP address or host name of the IP VCR. Note that recording IDs, recording console IDs, and auto attendant IDs are properties of folders (refer to Understanding the folders list) and can all be registered with the gatekeeper.
Gatekeeper registration type Controls how the IP VCR identifies itself when registering with its configured gatekeeper. Codian recommends that you use the Terminal / gateway option unless you are using a service prefix or point-to-point prefix (in this case, use Gateway).
the registration prefix is "99", then the • a recording console ID, that will start up recording will be registered with the the recording console gatekeeper with a gatekeeper ID of • a recording ID that will cause the IP VCR "992222" to start a recording and place it in the • register as a service prefix: the numbers folder associated with that recording ID are used as a service prefix for the IP VCR on the gatekeeper.
Deregister recording prefixes when all recording ports are in use When selected, configured recording prefixes (both the Prefix for IP VCR registrations if used as a service prefix and the Point to point call incoming prefix set for any folders) will be deregistered when all recording ports are in use on the IP VCR. This setting is for use in load-balanced environments.

For more information about this prefix, refer to the table above. Active registrations page If you click details, shown next to the Number of active registrations status entry, you are taken to the Active registrations page. This page shows the complete set of IDs that the IP VCR is attempting to register with the configured H.
IP VCR gatekeeper registration behavior This is a summary of the gatekeeper registration behavior on the IP VCR. It also explains how you can use a gatekeeper for load balancing. Choice of registered IDs With the exception of point-to-point prefixes (which are explained below), gatekeeper usage starts with configuring unique Numeric IDs for individual stored recordings and for folders.
1. If the Prefix for IP VCR registrations has been configured and the called number starts with that prefix, then the IP VCR tries to match the rest of the called ID number (i.e. the part after the prefix) to a recording's Numeric ID or to one of the folder IDs. 2. If a Play back prefix has been configured and it matches the called number, then the IP VCR tries to match the rest of the called number (i.e. the part after the prefix) to a recording's Numeric ID. 3.
Load balancing You can use prefixes to balance the load between a number of IP VCRs by registering them with the same prefixes and selecting the "deregister" options: • • the Play back prefix will be deregistered if the Deregister play back prefix when all play back ports are in use setting is selected and all play back ports are in use the Point to point call incoming prefix for all folders will be deregistered as will the Prefix for IP VCR registrations (if register as a service prefix is selected) if De
Configuring SIP settings SIP calls will select the audio and video codecs to use from those allowed on the Settings > Connections page, unless the call is with a endpoint configured with a Custom codec (refer to Configuring SIP endpoints for more information). Refer to this table for assistance configuring the SIP settings. After making any configuration changes, click Apply changes. Field SIP registration settings Field description Specifies the level of SIP registration for the IP VCR.
through a registrar or not. address Outgoing transport Whether the outgoing transport will be TCP or UDP. If your SIP devices use TCP, select TCP as the outgoing transport. If your SIP devices use UDP, select UDP as the outgoing transport. The IP VCR accepts connections on both TCP and UDP.
Configuring H.239 settings These settings affect the behavior of the IP VCR with regard to H.239. H.239 is the protocol that allows for an additional video channel (known as the content channel) alongside the main video channel in a video-conferencing call; for example, a user may wish to record a slide presentation from a laptop as part of a recording of themselves describing those slides. To access these settings, choose Settings > H.239. Refer to this table for assistance configuring the H.239 settings.
Adding a custom auto attendant banner You can add a custom banner image to the auto attendant configured on the IP VCR as follows: 1. Go to Settings > Banner. 2. Set the banner up using the table below to determine the most appropriate settings. 3. Click Update. Field Field description Usage tips Auto attendant banner Default Chooses the default Codian IP VCR graphic to use for your banner.
Configuring recording settings You may customize a variety of the recording settings for the IP VCR to most closely fit your needs. To view and change the recording settings, choose Settings > Recording. When you have finished editing any of the fields, click Apply changes to make them take effect.

Upgrading the firmware If you need to upgrade the firmware or activate features on the IP VCR, refer to these topics: • • • Upgrading the main IP VCR software image Upgrading the loader software image Enabling IP VCR features Upgrading the main IP VCR software image The main IP VCR software image is typically the only firmware component that you will need to upgrade. Follow these steps to upgrade this image: Check the Current version field to verify the currently installed version.
Enabling IP VCR features The IP VCR requires activation before most of its features can be used. (If the IP VCR has not been activated, the banner at the top of the web interface will show a prominent warning; in every other respect the web interface will look and behave normally.) Advanced IP VCR features (such as Video Firewall) are not enabled as standard, and require additional activation.
Shutting down and restarting the IP VCR It is sometimes necessary to shut down the IP VCR, generally to restart as part of an upgrade (see Upgrading the firmware). You should also shut down the IP VCR before intentionally removing power from the IP VCR. Shutting down the IP VCR will cause all playbacks to finish, allows the IP VCR to ensure that all recordings are cleanly ended and stored, and will disconnect all recording and playback H.323 connections.
Displaying general status The General Status displays an overview of the IP VCR status. To access this information, go to Status > General. Refer to the table below for details of the information displayed Field Field Description System status Model The specific Codian IP VCR model. Serial number The unique serial number of the IP VCR. Software version The installed software version. You will need to provide this information when speaking to Technical support.
Displaying recording status The Recording status displays the status of stored recordings and recordings being played back. To access this information, go to Status > Recording. Many of the fields show the current value, the highest value attained (in parentheses), and the maximum value the field may take. To reset to the maximum values, click Reset maximum values. Refer to the table below for assistance in interpreting the information displayed.
Total length of recordings The combined duration of all recordings accessible by the IP VCR. This includes recordings made using the IP VCR, those uploaded to it and those stored externally on an NFS server. Total length of internal recordings The combined duration of all recordings stored internally on the IP VCR. This includes recordings made using the IP VCR and those uploaded to it. Total size of internal The combined storage capacity used by all recordings stored internally on the IP VCR.
Displaying hardware health status The Health Status displays information about the hardware components of the IP VCR. To access this information, go to Status > Health. To reset these values, click Clear. Refer to the table below for assistance in interpreting the information displayed.
Working with the event logs If you are experiencing complex issues that require advanced troubleshooting, you may need to collect information from the IP VCR logs. Typically, you will be working with Codian Technical Support who can help you obtain these logs. Event log The last 2000 status messages generated by the IP VCR are displayed in the Event log page. In general these messages are provided for information, and occasionally Warnings or Errors may be shown in the Event log.
H.323/SIP log The H.323/SIP log page records every H.323 and SIP message received or transmitted from the IP VCR. The log can be exported in an .xml file. By default the H.323/SIP log is disabled because it affects performance, but Codian support may ask you to enable it if there is a problem with a unit in your network.
Logging using syslog You can send the Event log to one or more syslog servers on the network for storage or analysis. To configure the syslog facility, go to Events > Syslog In this section: • • Syslog settings Using syslog Syslog settings Refer to this table for assistance when configuring Syslog settings: Field Host address 1 to 4 Field description Usage tips Enter the IP addresses of up to four Syslog receiver The number of packets sent to each configured host hosts.
• • 22 - local use 6 (local6) 23 - local use 7 (local7) Using syslog The events that are forwarded to the syslog receiver hosts are controlled by the capture filter. To define a syslog server, simply enter its IP address and then click Update syslog settings. The number of packets sent to each configured host is displayed next to its IP address.
SIP: Advanced SIP implementation The IP VCR implements SIP as defined in RFC 3261. Any product wishing to establish SIP calls with the IP VCR should implement INVITE, ACK, BYE, and CANCEL messages along with responses from 1xx to 6xx. The IP VCR acts as a client and does not return 5xx and 6xx responses itself; however, proxies and other intermediaries may do so. To use a SIP registrar in conjunction with the IP VCR, you must register an ID for the IP VCR with the SIP registrar.
Customizing the user interface In this section: • • • Controlling the auto-refreshing of status pages on the IP VCR Controlling the display of thumbnail preview images Customizing voice prompts on the IP VCR The IP VCR provides you with options for customizing the voice prompts, the viewing of thumbnail previews, and for controlling the auto-refreshing of user interface pages.
The customization of voice prompts is controlled via the web interface. Go to Settings > User interface.
Viewing the available voice prompts You may review the voice prompt customizations available in the table headed Installed voice prompts. The Installed voice prompts list displays all voice prompt customizations, providing details for those which have alternatives uploaded. Because these lists can be quite long, by default they are hidden. Instead, the number of customizations (files) available is shown.
If you upload a file that is not in this format, the upload may fail or the voice prompt may sound distorted when heard by users. Use an audio editing package of your choice to make any conversions required. See Making the best possible recordings for how to obtain the best possible voice prompts for your IP VCR customization. Note that in addition to the 10 second length limit per prompt, there is a total length limit of 4 minutes for the full set of prompts.
You may wish to delete all customizations. To do this, press Delete all. Remember that you may revert to the default set of voice prompts without needing to delete any alternative customizations (see Using default US English voice prompts). Voice prompt specification Below is a complete list of the voice prompts that may be customized. The default wording is shown for each prompt. You do not have to use exactly the same wordings if they are not appropriate for your needs, and are provided only as a guide.
Volume Record prompts using a relatively constant loudness of voice. Although it may take some trial and error, the best recordings will result from speaking loud enough that the voice is recorded loudly compared to any residual background noise, but not so loudly that it sounds distorted when played back.
Customization: More information There are three customization levels on the unit (for voice-prompts, web interface, help pages, and text messages): • • • the factory default files that are provided in US English localization files that are sometimes installed by a reseller customized voice prompts files that can be uploaded and downloaded by you Precedence For every customizable file: 1. If there is a customization file present and Use customized voice prompts is checked, that file will be used. 2.
Backing up and restoring the configuration You can save the configuration of the IP VCR to a file that you can store away from the unit. If necessary this file can be used to restore the configuration of the unit. To back up the configuration: 1. Ensure that the FTP service is enabled on the Network > Services page. 2. Connect to the IP VCR using an FTP client. When asked for a user name and password, enter the same ones that you use to log in to the unit's web interface as an administrator.
Network connectivity testing The Network connectivity page can be used for troubleshooting issues that arise because of problems in the network between the IP VCR and a remote video conferencing device being called (or a device from which a user is attempting to call the IP VCR). The Network connectivity page enables you to attempt to 'ping' another device from the IP VCR's web interface and perform a 'traceroute' of the network path to that device.
Configuring SSL certificates If the IP VCR has the Secure management (HTTPS) feature key installed, and you enable the secure web service on the Network > Services page, you will be able to access the web interface of the IP VCR using HTTPS. The IP VCR has a local certificate and private key pre-installed and this will be used by default when you access the unit using HTTPS.
