[SR-Users] Cancel issue

[Carl Wagner]

I am sorry, you are right.   I was looking at rfc3665 Page 71, F10 and 
it did not have a To: tag in the 200 OK to the cancel.
(I know that rfc3665 is just examples, and when in doubt I should use 
rfc3261)

The last paragraph of rfc3261, section 9.2 says to use section 8.2.6 to 
construct the 200 (OK).


Not sure why Asterisk is not liking the 200 Canceling.
Does anyone see anything wrong with the Cancel or the 200 Canceling in 
the log below?
(I just included interactions between Asterisk and Kamailio as the other 
side of Kamailio looks to be working OK)
