Hi,
The SIP bis draft02 , says the following in Table 4:
Header-field where proxy ACK BYE CAN INV OPT REG
________________________________________________
Contact R o - - m o o
which states that CONTACT header is not applicable to BYE request, but there
is another statement in the draft which contradicts this :
2.2 Non-SIP URLs
SIP header fields and the Request-URI MAY contain non-SIP URLs, with the
exceptions noted below.In the following locations, only SIP URLs are
allowed:
Request-URI in a REGISTER request;
Contact header field in INVITE, OPTIONS and BYE and 2xx responses.
In the above statement , it indicates that CONTACT header
can exist in the BYE Method.
Can someone please put light on the above contradictions and help me come to
a conclusion regarding "the existance of Contact Header in a BYE method".
Thanks and Regards,
rahul
