RFC support
Support Locating
SIP Server (RFC
3263)
Select this option to have the Router use DNS procedures to resolve the SIP domain
and find the SIP server’s IP address, port number and supported transport
protocol(s).
The Router 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 Router 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.
RFC 3262 RFC 3262 defines a mechanism to provide reliable transmission of SIP provisional
response messages, which convey information on the processing progress of the
request. This uses the option tag 100rel and the Provisional Response
ACKnowledgement (PRACK) method.
Select this to have the Router include a SIP Require/Supported header field with the
option tag 100rel in all INVITE requests. When the Router receives a SIP response
message indicating that the phone it called is ringing, the Router sends a PRACK
message to have both sides confirm the message is received.
If you select this option, the peer device should also support the option tag 100rel to
send provisional responses reliably.
