Re: [Serusers] CANCEL handling

Hello,

I just noticed that SER is not generating a 200 OK as reply for a CANCEL but rather a 200 cancelling.

yes...the rfc doesn't impose the reason phrase, just the code

Then it is also generating a 487 Request cancelled what is supposed to be generated by the other end device reveiving the CANCEL.

SER does a hop-by-hop cancellation of the INVITE.

How is this possible? Is this according to RFC3261?

yes, but this approach can generate race conditions (cancelling before the INVITE get to target UAS); on the other hand solves the problem with UASs that don't generate 487 for Cancels.
