Yes, I know that, but that is not what I meant. Please read the example in my previous mail (I try to improve it): - Alice calls Bob through a proxy. - Proxy sends the INVITE to Bob and replies 100 to Alice. - Proxy gets no provisional response fmo Bob. - Alice sends CANCEL after a while. - Proxy replies 200 for CANCEL. - Proxy doesn't send CANCEL to Bob as there is not 1xx response. - Some seconds later Bob replies 1xx. - Should then the proxy send a CANCEL to Bob? Thanks a lot. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
