[reSIProcate] How to terminate a call when received 200 OK ?

[Karlsson <boost.regex@xxxxxxxxx>]

Hi, there is my case:

1: UAC call UAS without the SDP
2: UAS reply 200 OK with SDP
3: UAC got the onOffer callback, then parse SDP and try to match codec 
4: Match the codecs failed, then want to reject/terminate this call, how to do ?

I have try to hang up it, but the server says: 481 Call/Transaction Does Not Exist


thanks
