Voice over IP (VoIP) Application Note

HP iPAQ 500 series Voice Messenger

The goal of this document is to clearly and concisely state what HP iPAQ 500 series

Voice Messenger is and is not capable of supporting for mobile IP telephony, aka VoIP,

or Voice over IP. All the capabilities and interoperability scenarios haven’t been tested at

this point, and until then this document will be a work-in-progress. As new information

becomes available, it will be added to this document.

1 Overview Mobile IP telephony services can be separated into three broad categories, each with its own specific target markets and technologies used. These categories are illustrated below: Tested use cases for the built-in VoIP client on the HP iPAQ 500 series smartphone cover the enterprise VoIP segment exclusively and expect the enterprise has IT staff that manage their own IP-PBX systems and provision devices for enterprise users.

     Audio Quality Hardware and Firmware WLAN Infrastructure IP-PBX and SIP Server Support Accessory Support While Internet voice services delivered by Internet Telephony Service Providers (ITSPs) may also be based on SIP, HP has done no testing or validation of interoperability with these services at this time. 2 Media and Signaling Protocols This category is related to the industry protocols that exist today for carrying control messages and media messages.

Supported:             Originate and Terminate Calls Caller ID Call Waiting Call Hold Call Mute Call Forwarding *only with a SIM card present o The number the call is forwarded to must be in a format [E.164] that can be validated on the GSM network. Configuring Caller ID *only with a SIM card present Configuring Call Waiting *only with a SIM card present Call Barring *only with a SIM card present Blind Transfer In-Band and out-of-band DTMF o Out-of-band DTMF is requested by default.

     5 Adaptive Jitter Buffer Management Voice Activity Detection Silence Suppression Comfort Noise Generation Acoustic Echo Cancellation (3rd party sourced, not provided by Microsoft) Hardware and Firmware This category is related to WLAN and other hardware/firmware components in the handset that are critical to the performance and usability of VoIP. Supported:    802.11b/g 802.
PAGE 6
WLAN Infrastructure This category is related to the wireless local area network (WLAN) infrastructure to which the handset connects to send and receive IP traffic. The key consideration from the mobile handset perspective is typically AP-AP roaming. Given the real time requirements of voice and the delays inherent in WLAN authentication (802.11i), the strongly recommended answer is a VoIP-enabled pervasive enterprise WLAN infrastructure.

and that VoIP will be used for the next outgoing call. The Phone Dialer can be used to make and receive VoIP calls. The Internet Calling status can be toggled between ‘Available’ and ‘Selected’ by pressing the Action [Enter] button on the Internet Calling plug-in on the home screen. If the status of the plug-in is ‘No Service’, it indicates that the registration was unsuccessful. This could be due to lack of Wi-Fi access, the IP-PBX being unavailable or some other failure. 9.
