Hello, I'm just find another bug when call negotiation is wrong. Here, what I do to make it: turn on pjsua app with: --video --auto-answer=200 --vcapture-dev=1 --dis-codec=speex --dis-codec=G722 --dis-codec=iLBC --dis-codec=GSM //turn off all audio codec without PCMA/PCMU turn on another voip client (x-lite) turn off pcma/pcmu codecs then in pjsua_app write vid disable and I will try make some call from x-lite to pjsua after that I get establish connection with audio and video 0 port... I think that, app should reject this call. I have also one another question: Is there possible to check what codec offer me remote user in onIncomincCall callback?
