SIP audio provider settings

To configure your SIP audio provider through the Management Station, open the Advanced tab of the Telephony Session service properties page.

In a complete commercial configuration or deployment, you need to set the following service properties:

  1. Set the audio.sip.ProxyServerURI to the proxy server address or name; for example:

audio.sip.ProxyServerURI=sip:proxy.nuance.com (for applications A and B)

  1. Set the audio.sip.LocationServerURI to the location server address or name; for example:

audio.sip.LocationServerURI=sip:nuance-tel.com (for applications A and B)

  1. Set the audio.sip.UserAgentURI and audio.sip.UserAgentPort to register each user agent with the location server.

By default, audio.sip.UserAgentPort is set to 5060 for a single Telephony Session service instance. When using multiple instances, the default value for audio.sip.UserAgentPort is increased by 10 for each new instance. For example, a host running four instances uses 5060, 5070, 5080 and 5090 by default. You need to set this service property only if you do not want to use the default value(s).

Each user agent must use a separate port. For example:

For application A:

  • audio.sip.UserAgentURI=sip:18003211066@nuance-tel.com
  • audio.sip.UserAgentPort=5078

For application B:

  • audio.sip.UserAgentURI=sip:18003211067@nuance-tel.com
  • audio.sip.UserAgentPort=5079

Note: You cannot start more than one application with the same port number. See the Speech Suite documentation for a list of the default values for all ports reserved by Voice Platform for SIP communication. You must not use these ports when setting ports for external SIP applications.
