That was indeed the reason for my confusion. I think Contact is supposed to be sip URI for 200 OK or INVITE .
One should note that the original spec (2543) had Contact optinal but now Contact is required in certain cases. Consequently it makes life very confusing when Contact is not a SIP URI. I would be grateful if somebody could give me an example where contact is not SIP URI and why not just mandate that the Contact header must always be a SIP URI in the ABNF as Prasanna is asking below?
Thanks
Ranga.

Section 8.1.1.8 mentions that the Contact should be a SIP/SIPs URI. But--
this section does not form a part of the normative definitions. However the
ABNF in section 25 allows any URI.
If the specs enforces the Contact to be a SIP/SIPs URI should'nt the ABNF
also reflect it.

Subject: [Sip-implementors] Are non-sip URLs in Contact allowed?
Hello!
Does the latest spec allow non-sip urls in the contact header? If so,
how are non-sip URIs in contact headers interpreted?
Thanks for your replies.
Regards
Ranga
