Chapter 4. How To Configure SIP

Routing

If the SIP server is located on a NATed network, all SIP traffic from the outside will be directed to the Telecommuting Module, which must know where to forward it.

One way to do this is to enter the SIP domain in the DNS Override For SIP Requests table on the Routing page, to link the SIP server IP address to the name. The Telecommuting Module will look up the domain here instead of in the DNS server, and send the SIP traffic to the correct IP address.

Interoperability

You need to set the URI Encoding settings on the Interoperability page to "Use shorter, encrypted URIs".

Filtering

To allow SIP traffic through the Telecommuting Module, you must change the Default Pol- icy For SIP Requests on the Filtering page.

As the Telecommuting Module does not manage any SIP domains, there are no Local SIP Domains. This means that you must select Process all for this setting.
