Talkswitch 48-CA User Manual page 37

This TalkSwitch location is the Proxy / Registrar
If this location is going to be the Proxy / Registrar Server, then check this box.
When enabled and other SIP devices are registered with this system, then any calls
made within the group contact this device to resolve the destination location. Once
the destination is resolved, the call is made directly from the source location to the
destination location.
The TalkSwitch Registrar supports Digest authentication. The Digest mechanism is a
challenge/response protocol in which the client presents its credentials in response
to a challenge from the server. This method of authentication is very secure. To
enable authentication, select 'yes (digest)' from the drop-down list under Registrar
Authentication

port number than the default, then specify the port number after a colon at the
end of the domain or IP address. Example voip.domain.com:5061

Proxy associated with the Service Provider.

unit. (for example, 'domain.com'). Note: This field is only required when TalkSwitch

domain associated with the service provider.
If this unit is not the Proxy/Registrar, then it must have the same realm filled in as
the Registrar Server.
