Chapter 4. How To Configure SIP
Surroundings
To make the Telecommuting Module aware of the network structure, the networks defined above should be listed on
the Surroundings page.
One effect of this is that traffic between two users on different networks, or between one of the listed networks and
a network not listed here, is NAT:ed.
Another effect is that for connections between two users on the same network, or on networks where neither is
listed in Surroundings, no ports for RTP sessions will be opened, since the Telecommuting Module assumes that
they are both on the same side of the firewall.
Normally, at least one network should be listed here. If no networks are listed, the Telecommuting Module will not
perform NAT for any traffic.
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.
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.
