Chapter 4. How To Configure SIP
Basic
Go to the Basic page under SIP Services and turn the SIP module on. Here you also select log classes for SIP event
logging.
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
If Windows Messenger is used for SIP communication, you need to set a parameter on the Interoperability page.
Set lr=true status to On under Loose routing.
