Chapter 4. How To Configure SIP

When the configuration has been applied, you should save a backup to file. Press Save config to CLI file to save the 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 on the LAN

For various reasons, you might want to use a separate SIP server instead of the built-in server in the Telecommuting Module. That SIP server would be 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 Settings

Go to the Basic Settings page under SIP Services and turn the SIP module on. Here you also select log classes for SIP event logging.
