Chapter 7. Firewall and Client Configuration
The SIP clients
SIP clients will use the Telecommuting Module as their outgoing SIP proxy and as their registrar (if they can’t be configured with the domain only). If you don’t want to use the Telecommuting Module as the registrar, you should point the clients to the SIP registrar you want to use.
Other
The DNS server used must have a record for the SIP domain, which states that the Telecom- muting Module handles the domain, or many SIP clients won’t be able to use it (if you don’t use plain IP addresses as domains).
