Making SIP calls without proxy server:
The SIP protocol allows you to make SIP calls directly to the destination number without through the
proxy server. You can simply dial the SIP number to connect other SIP gateway. The typical
example is:
[email protected] . Other SIP gateway that had already configured
[email protected] in Phone Book can connect this gateway by number 413189 without
routing through SIP Proxy.
Notice: For this type of SIP calls, the destination device’s IP address is already known and fixed.
