SIP Callee does not get notification that call ended_问答_开发者

I have deleted my previous question and post this updated:

I have a an issue with my SIP UAC, once I received a ringing from the B2BUA on both the caller and callee, and the caller hangs up the call while the call is ringing (I send cancel request and receive "request terminated" on the caller side), the callee does not get any notification that the call has been terminated by the caller.

But when the callee declines the call, the caller gets a busy here.

Here is the Callee side:

I must decline at the callee end, because if I don't respond to the request, the callee account get stuck in a loop and then the client returns busy forever, and requests does not reach that client, or at least until the account is deleted.

And there is another thing, the B2BUA does not send anything back to the decline response, shouldn't I get an ACK from the server?

And here is the Caller side:

Frank, I tried to pay attention to your details, perhaps I missed something, since the other side still does not receives notification on an early hang up.

Any idea why?

Thanks in advance,

Adam.

1) 6xx is unusual; normally rejecting a call is done with a 4xx (usually "Busy Here")

2) The lack of cancel to the destination is a bug in the sip server. (Ok, they're not required to send a CANCEL if you cancel, but they really should.)
