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.
