Chapter 4. How To Configure SIP
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.
Client Settings
SIP clients will use the Telecommuting Module as their outgoing SIP proxy and the SIP domain as the registrar.
DMZ/LAN Telecommuting Module, SIP server inside
You might instead have a SIP server of your own, located on the inside or maybe on a DMZ.
If the SIP server is located on a NATed network, DNS queries for the SIP domain should point to the
Telecommuting Module, which in turn will forward the SIP traffic to the server.
Note that the Telecommuting Module must have a public (non-NATed) IP address for the SIP signaling to work
correctly.
Here are the settings needed for this. It is assumed that the Telecommuting Module already has a network
configuration. Only the additional SIP settings are listed.
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.
