Chapter 4. How To Configure SIP
If the SIP server is an LCS (Live Communications Server) or some other server that does not accept more than one
Via header in SIP packets, you must enter the SIP server IP address in the Remove VIA headers table. This will
make the Telecommuting Module strip SIP packets of extra Via headers when it sends those packets to the server,
and add the Via headers when the response packets are received.
Basic Configuration
If no other SIP routing information is entered, the Telecommuting Module must be able to look up SIP domains in
DNS. DNS servers are entered on the Basic Configuration page under Basic Configuration.
Save/Load Configuration
Finally, go to the Save/Load Configuration page under Administration and apply the new settings by pressing
Apply configuration.
Standalone Telecommuting Module, SIP server on the
outside
The simplest SIP scenario is when the SIP server is managed by someone else, and the Telecommuting Module SIP
function is only used to traverse NAT.
Note that the Telecommuting Module must have a public (non-NATed) IP address for the SIP signaling to work
correctly.
