Hi,
In draft-ietf-sip-call-flows-05.txt
7.33 REGISTER with a Escaped Header in a Illegal SIP URL of a Contact
A server should respond 400 for following message.
REGISTER sip:company.com SIP/2.0
To: sip:[EMAIL PROTECTED]
From: sip:[EMAIL PROTECTED]
Contact: sip:[EMAIL PROTECTED]
Call-ID: [EMAIL PROTECTED]
CSeq: 1 REGISTER
Via: SIP/2.0/UDP 135.180.130.133
Contact: sip:[EMAIL PROTECTED]?Route=%3Csip:sip.example.com%3E
Draft says this is an illegal message as
REGISTER request contains a SIP URL with an escaped header but it is not
enclosed in <>.
My doubt:
If we see BNF of Contact header above line seems to be valid as u can
have name-addr or addr-spec.
Thus "<>" may not be present (although this may lead to ambiguity) and
message is still gramatically
correct.
Can you clarify why this message should fail ?
Which section in sip rfc indicates so..
Thanks
