Hi, I'm new to pjsip. I'm using it in a c#-sharp with sipeksdk-csharp wrapper. So SipekSDK does not provide a state if a outcoing call busy. For a while I changed SipekSDK from pjsip 1.03 to 1.3, this is the pjsip version I use now. I found that pjsip_inv_state does also not provide a state for busy. Is there any chance to distinguish between disconnect by no answer or disconnect by state busy? Hope you can help me out. Greetings, Bj?rn
