Its very much a part of the bis draft
See section 1.5.1

Quote:

"A server which transmits a provisional response should retransmit it upon
reception of a duplicate re-quest.
A server which transmits a final response should retransmit it with an
interval that starts at T1
seconds, and doubles for each subsequent packet until it reaches T2
seconds. Response retransmissions
cease when any one of the following occurs:

1. An ACK request for the same transaction is received;
2. a BYE request for the same call leg is received;
3. a CANCEL request for the same call leg is received and the final
response status was equal or greater
to 300;
4. the response has been transmitted 7 times."

Subject:  [SIP] how to retransmit final response ?

 Hi All;

What is the policy for reliability of final responses in UDP  ?

I didn't find anywhere in the SIP RFC the way to retransmit final
responses.

Can anyone of you help me  ?

Thanks

Rachid
