Re: [Sip-implementors] CANCEL for non-INVITE requests

I think it is mentioned in RFC that CANCEL is best sent for an INVITE sessions only. Moreover, on the tag issue it depends on whether the UAC has got back a repsonse with a tag or not, if it has not there is not choice for UAC. regards Rayees [EMAIL PROTECTED] wrote: -To: "Sip-Implementors (E-

Re: [Sip-implementors] CANCEL request in the INVITE initiated Dialog

The CANCEL MUST have the same to-tag as the INVITE it is cancelling. If the INVITE had a to-tag, the CANCEL MUST have the same to-tag. If the INVITE did not have a to-tag, the CANCEL MUST NOT have a to-tag. Section 9.1 of RFC 3261 is very clear on this: The Request-URI, Call-ID, To, the numer

Re: [Sip-implementors] CANCEL request in the INVITE initiated Dialog

Hi One more reason why To tag is optional in Cancel, since Cancel will be matched with the transaction of INVITE and for the transaction match To tag is not required, rather it matches with Branch-Id. Branch-Id being unique will identify which INVITE it is cancelling. Regards, Manju -

Re: [Sip-implementors] CANCEL request in the INVITE initiated Dialog

The CANCEL should be identical to the corresponding INVITE request. So, it should not have the To tag. However, incase of a re-INVITE, the INVITE itself will set the To tag. So, in that case the CANCEL must carry the To tag. Aza. Banibrata Dutta wrote: >hi, > >a CANCEL sent for an INVITE will

One case is: 1. If a Server with a policy that requires a particular specification and receives a request that does not Contain that specific tag in require/supported headers returns 421. Example: sec-agree option tag is not present in Require/supported headers, server responds with 421.. HT
