Subject: [Sip-implementors] "Contact" header in 200 OK for REGISTER method

 

Hi All,

According to 3261 RFC , conatct header is medatory in 200 OK for REHISTER

 

� 10.3 Processing REGISTER Requests says:

8. The registrar returns a 200 (OK) response.  The response MUST contain
Contact header field values enumerating all current bindings.  Each Contact
value MUST feature an "expires" parameter indicating its expiration interval
chosen by the registrar. The response SHOULD include a Date header field."

 

[Chris Boulton] It MUST contain all current bindings – If there are not bindings then the contact header does not need to be included.

Chris.


 

Can any body please explain me why in RFC 3261 , in list of header fields of section 20 "contact"  is optional in 200 OK for REGISTER.

 

 

 

rgds,

-Sushil
