VoIP gateway settings

Configure the VoIP gateway to send SIP calls the URI defined in the proxy server. The gateway must use the G.711 u-law or a-law codec. Voice activity detection (VAD) must be turned off.

This example shows how to configure a Cisco VoIP gateway.

1. Since you have a DNS entry for the proxy server as specified in the previous section, set the sip-server property to the name of the SIP proxy server; for example:

sip-server dns:proxy.nuance.com

2. In the Cisco dial-peer, set the destination properties as follows:
   1. Set the destination-pattern to the telephone number for the application.
   2. Set the session protocol to sipv2.
   3. Set the session target to point to sip-server (the same value set above).
   4. Set the codec to g711ulaw, and ensure an RTP packet size of 30 ms (Voice Platform default).
   5. Make sure voice activity detection is not enabled.
