Chapter 4. How To Configure SIP
Basic Configuration
If no Outbound proxy 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.
When the configuration has been applied, you should save a backup to file. Press Save config
to CLI file to save the configuration.
Standalone Telecommuting Module, SIP
server on the WAN
The simplest SIP scenario is when the SIP server is managed by someone else, and the
Telecommuting Module SIP function is only used to traverse NAT.
Note that the Telecommuting Module must have a public (non-NATed) IP address for the
SIP signaling to work correctly.
