Chapter 2 SRG50 overview SRG50 terminology The table SRG50 terminology on page 20 identifies SRG terms that may be unfamiliar to main office installers. They are provided to facilitate communications between SRG and main office personnel. In the table, the Element Manager path where the term appears is provided for reference and may not represent every appearance of the term.
Chapter 2 SRG50 overview 21 Table 6 SRG50 terminology (Sheet 2 of 2) Term Description Target Lines Target lines are internal, virtual paths between trunks and telephones for incoming calls (only). They provide flexibility in the way trunks and telephones can be associated: target lines can be used to direct an incoming call to one or more telephones, direct one or more trunks to one phone, or direct several trunks (in a line pool) to one or more phones. Target lines are assigned to DNs.
Chapter 2 SRG50 overview Figure 1 Normal mode Main office Branch office SRG IP phones IP phones WLAN handsets Software phones VoIP connection over WAN Normal mode IP telephones connected at the SRG are registered with the main office call server and are under main office control. They operate as branch user sets and have access to all telephony services and features that the call server offers to IP telephones connected directly to the main office.
Chapter 2 SRG50 overview 23 Local mode In the event of a WAN failure or the call server at the main office becomes unavailable, the IP Phones in normal mode revert to local mode automatically. In local mode, the IP users connected to the SRG are under the control of the SRG. When in local mode, main office call features are not available to users attached to the SRG.
Chapter 2 SRG50 overview Automatic registration with the main office When configured as a branch office user set, an IP telephone at the SRG automatically attempts to register with the main office when: • • • The phone is in local mode because of loss of connectivity with the main office, and the SRG is redirecting it back to the main office because connectivity has been reestablished (see Loss of WAN or VoIP connectivity on page 24).
Chapter 2 SRG50 overview 25 The figure Process map for installing and configuring an SRG on page 26 provides a process map for installing and configuring an SRG50.

DN (directory number) The dialable number of a telephone at the SRG when it is called from another phone at the SRG. In the case of a CDP dialing plan, it is recommended that the BUID and the SRG DN be the same.
Chapter 4 CS 1000 considerations 35 Normal and local mode overview Normal mode and local mode overview provides a description of the following sections: • • • • • “Normal mode” on page 35 “Local mode” on page 35 “Survivability” on page 36 “Recovery to normal mode” on page 37 “Testing the telephone in local mode” on page 37 Normal mode IP Phones that are physically located at the SRG but are registered with the main office are operating in normal mode.
Chapter 4 CS 1000 considerations services, such as transfer, last number redial, and single key access through the PSTN to a centralized voice messaging system are supported. Local PSTN access and local Emergency Services access is also supported. No local applications or Business Communication Manager features are supported in local mode operation. Analog devices continue to be under the control of the SRG50 system.
Chapter 4 CS 1000 considerations 37 If the main office Signaling Server fails and an Alternate Signaling Server is available, the SRG IP Phones reset and reregister with the SRG. The SRG will then query the NCS for the Alternate Signaling Server’s IP address. The SRG will redirect the IP Phone to the Alternate Signaling Server and continue to receive call processing services from the main office Call Server.
Chapter 4 CS 1000 considerations Virtual trunk capacity The SRG supports a number of simultaneous calls depends on the specific codec type used. SRG50 supports 24 virtual IP trunks that are either H.323 only, SIP only, or a combination of the H.323 and SIP. In normal mode, the codec selection used is controlled by specific programming of the CS1000. In this case: SRG50 supports up to a maximum of 15 Virtual trunks unless both the intrazone and interzone codecs are configured as Best Quality (G.
Chapter 4 CS 1000 considerations 39 Network Bandwidth Management (NBWM) The SRG interoperates with the Network Bandwidth Management (NBWM) feature in a manner similar to Media Gateway (MG) 1000B, though only G.711 and G.729 codecs are supported. At the SRG, a Virtual Private Network ID (VPNI) and Zone ID are entered with values defined by the main office configuration (see Bandwidth management configuration: NBWM, ADBWM, and ACR on page 40). The VPNI and Zone ID allow the CS 1000 to recognize that H.
Chapter 4 CS 1000 considerations Bandwidth management configuration: NBWM, ADBWM, and ACR To configure SRG for NBWM and ADBWM 1 Obtain the Virtual Private Network ID and the Zone ID numbers configured at the main office. 2 Use Element Manager to enter these numbers in the appropriate fields at Configuration > Telephony > Dialing Plan > Private Network > Dialing Plan - Private Network panel > VoIP subpanel (see the figure Dialing Plan - Private Network panel, VoIP subpanel on page 40).

Chapter 6 Setting up the private VoIP network To provide SRG functionality and to take advantage of VoIP technology, a private VoIP network is required between the SRG and the main office. This chapter details the procedures for establishing appropriate WAN connections to enable a VoIP network between the main office and SRG branch locations.
Chapter 6 Setting up the private VoIP network Figure 12 VoIP path for SRG operation Main office Branch office SRG IP phones IP phones IP network connections WLAN handsets Software phones VoIP trunks IP Networking + VoIP trunks Generic procedures for setting up a private network on the SRG are covered in the Networking Configuration Guide (NN40020-603).
Chapter 6 Setting up the private VoIP network 67 Basic parameters The table Basic parameters on page 67 provides a record of basic parameters that are significant for SRG operation. Typically, these parameters are specified as part of BCM50 foundation activities; in most cases, their configuration is not covered in the SRG50 Configuration Guide. Table 15 Basic parameters (Sheet 1 of 2) Parameter DN length Value Context Configured as part of BCM50 foundation configuration.

Chapter 6 Setting up the private VoIP network 69 Figure 13 Dialing Plan — Private Network panel, Private Network Settings subpanel Meridian Customer Defined Network (MCDN) MCDN is automatically activated when the system is converted to SRG operation. To ensure that redirected IP telephones can transfer calls to the SRG local telephones, trunk anti-tromboning (TAT) must be enabled.
Chapter 6 Setting up the private VoIP network Figure 14 Dialing Plan — Private Network panel, MCDN subpanel QoS settings (codec, jitter buffer, and related items) Quality of Service (QoS) settings for the VoIP trunks at the SRG are determined by the main office settings; the SRG settings must match the main office. Use the table Main office QoS settings on page 70 to record the main office settings, to facilitate configuration, and to provide a record of the datafill.
Chapter 6 Setting up the private VoIP network 71 Table 16 Main office QoS settings (Sheet 2 of 2) Media parameter H.323 settings SIP settings G.723 payload size (ms) Supported for IP telephones for local calls only. See IP telephone codec and jitter settings on page 55 for details. G.711 payload size (ms) Incremental payload size (yes/no) -- T.38 fax (yes/no) -- Force G.711 for 3.
Chapter 6 Setting up the private VoIP network Network security Firewall configuration for SRG is the same as for the BCM50 and is detailed in the Networking Configuration Guide (NN40020-603). Firewalls cannot be configured to allow VoIP pass through. Instead, the SRG supports IPsec tunnels to provide VoIP pass through. IPsec tunnels are also covered in the Networking Configuration Guide (NN40020-603).
Chapter 6 Setting up the private VoIP network 73 Gatekeeper routing The gatekeeper routes the calls based on an internal numbering table. Ensure that the gatekeeper administrator has a list of the numbers that identify the SRG and the SRG PSTN. Examples: • • If the system is running with a CDP dialing plan and the SRG DN range is from 3000 to 3199, the gatekeeper requires this information to establish that calls starting with 30 and 31 are routed to the SRG.
Chapter 6 Setting up the private VoIP network When you set the value of the RFC2833 Dynamic Payload field, if the value is greater than 0, then this feature is enabled. If the feature is enabled then DTMF digits are sent in RTP packets. For CS1000 Release 4.5 set the value to 0. For detailed information on entering the values in this panel, see the Networking Configuration Guide (NN40020-603). Line pools Both VoIP trunks and PSTN trunks must be configured in separate line pools.
Chapter 6 Setting up the private VoIP network 2 c Change the schedule name (optional). In this procedure, the name SRG is used as the name of the schedule. d In the Services subpanel, select your schedule. e In the Routing Svc row for your schedule, select Auto from the list. f Select the Overflow checkbox for your schedule. g Change the schedule time so that the schedule runs continuously (Start Time 00:00:00, Stop Time 23:59:59, MTWTFSS).
Chapter 6 Setting up the private VoIP network h In the adjacent Absorbed Length field, select the number of digits to be absorbed. The Absorbed Length applies to the digits of the destination code only. i In the Second Route field, enter 999 (the PSTN route). j In the adjacent Absorbed Length field, select the number of digits to be absorbed. Depending on the dialing plan, the destination code is integrated with the DN or is dialed as a prefix to the DN.
Chapter 6 Setting up the private VoIP network 77 PSTN destination codes configuration To allow SRG telephones to dial out over the PSTN and to allow main office telephones to tandem out through the local SRG PSTN, you need to define a destination code that accesses the PSTN line pool without an External Number. Frequently, this code is 9, but it does not have to be. The following procedure provides a basic PSTN routing setup.
Chapter 6 Setting up the private VoIP network b Assign the Normal and SRG scheduled route for the two destination codes. Main office information The SRG requires information about the main office call server that is not needed for a BCM50. Element Manager accommodates this information with SRG-specific panels that are activated after the SRG50 keycode is applied. The information required for these panels is specific to the main office call server CS 1000 considerations on page 33.
Chapter 7 PSTN access and analog devices SRG-specific items relevant to PSTN trunks and analog devices include: • • PSTN access considerations on page 79 Analog devices considerations on page 79 PSTN access considerations Consider the following for PSTN access: • • PSTN access To provide access to the SRG PSTN when the SRG is in local mode, or to be able to set up tandem dialing from the main office through the SRG to the SRG PSTN, one or more PSTN trunks must be configured on the system.
Chapter 7 PSTN access and analog devices • Access to system features Analog telephones do not have a Feature key. Instead, they use a Link (*) key to access system features.
