In other words, it is intended to be used as test equipment rather than as a SIP phone application. IPV does not yet include support for the SIP protocol. The IPV test software can be used as a piece of test equipment to facilitate the testing of VoIP phones and gateways.

The following VoIP features are included in IPV Test:

• RTP/Jitter Buffer
• G.711 mu-law and a-law with packet loss concealment
• G.729A 8 kbps speech compression
• G.722 Wideband
• Acoustic Echo Cancellation
• DTMF Relay Transmit (IETF RFC 2833)
• 10, 20, and 40 msec frame sizes

The following test features are included in IPV Test:
• Tone transmit
• Tone receive
• CSS transmit
• CSS receive
• Acoustic Delay Measurement

To download IPV test software application:
