And what says the RFC about a proxy which does parallel forking? Then there may be multiple 180 ringing with multiple to tags. Which one should be used?
Good point!
So, what should I do? reportabug to RFC because what it says about CANCEL is not possible whith parallel forking? maybe report a bug to Asterisk to be **in this case** to much RFC compliant?
Further, what if the callee has not sent a response yet - then openser also does not know which to-tag to use.
RFC says: "If no provisional response has been received, the CANCEL request MUST NOT be sent; rather, the client MUST wait for the arrival of a provisional response before sending the request."
But the question is: what about if the only response is a 100 Trying that doesn't include To tag?
I nave had such problems with Asterisk yet. Do you use Asterisk in pedantic mode?
Yes, I use it. If I take it off it seems to work "better" but...
Thanks for all.
