Locating SIP
Server (RFC
3263)
Select this option to have the P-2812HNU-51c use DNS procedures to
resolve the SIP domain and find the SIP server’s IP address, port
number and supported transport protocol(s).
The P-2812HNU-51c first uses DNS Name Authority Pointer (NAPTR)
records to determine the transport protocols supported by the SIP
server. It then performs DNS Service (SRV) query to determine the port
number for the protocol. The P-2812HNU-51c resolves the SIP server’s
IP address by a standard DNS address record lookup.
The SIP Server Port and REGISTER Server Port fields are grayed
out and not applicable and the Transport Type can also be set to
AUTO if you select this option.
