Hi Rohit,

The CANCEL should not have To tag as the CANCEL request must be identical
to the correponding  INVITE Request
as explained in section 9.1.

Thanks
Partha

If an INVITE has received a provisional response, should the CANCEL sent
now include the tag in the To header that appeared in the provisional
response. Section 9 says the To header should match the request being
cancelled, so I am not sure.



Thanks.

Rohit
