Locating SIP
Server
(RFC3263)
Select this option to have the VMG use DNS procedures to resolve the SIP domain and find
the SIP server’s IP address, port number and supported transport protocol(s).
The VMG 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 VMG resolves the SIP server’s IP address
by a standard DNS address record lookup.
The SIP Server Port and REGISTER Server Port fields in the General section above are
grayed out and not applicable and the Transport Type can also be set to AUTO if you
select this option.
