Oops, I figured out the problem. It has to do with the SipXTapiDotNet abstraction. It saves each call received in a collection, which I mistakenly thought matched the value of the handle. It seems rather to fix this code you would just do:
call= sipx.Lines[line].Calls.Count; //get the latest new call created on the stack/collection sipx.Lines[line].Calls[call].Accept(); Jason Hillier Digital Business Solutions LLC Office: (800) 768-0213 Cell: (801) 682-5580 http://www.thedigitalanswer.com <http://www.thedigitalanswer.com/> From: Jason Hillier Sent: Wednesday, August 15, 2007 12:24 PM To: [email protected] Subject: callstateevent.offering Hi everyone, I'm new to sipxtapi and was hoping someone could help me. I have a functioning SIP phone client which can call and receive calls (is connecting through asterisk proxy). However, whenever a second call comes through, I get a KeyNotFoundException when try to execute sipx.Line[line].Calls[call].Accept(); method on Offering event. Like so (C#): When e.CallStateinfo.StateEvent == SipXTapiDotNet.SipxCallStateEvent.Offering://pseudo call=e.CallStateinfo.CallHandle.ToInt32(); sipx.Lines[line].Calls[call].Accept(); //[also tried with just .Answer()] The first time a call comes in, this code executes correctly, and the call gets Answered. The second time a call comes in I get a KeyNotFoundException indicating the 'call' is invalid. Why does it work once but not a second time? I made sure to close previous call handle. Reinitializing the line would probably work, but then I would lose registration with the SIP server. FYI on the first offering, call=2. On the second, call=5 (which it then says KeyNotFound). Don't know if that helps any. Anyone know what I am doing wrong?
