But the important thing is "the same address is used for the request, any retransmissions, any associated CANCEL requests and ACK requests for non-2xx responses.".

The whole next-hop selection is done once per transaction rather than per request. _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
