> Im having an issue that I think is on sdp negotiation. using webrtc
> basically is one way audio, but this is not nat related, the problem is when I have 2 peers with audio and video capability, when both have this capability the part that answer the call answers with video even when on the initial INVITE theres is no video, but I think is using the capabilities of the peer instead of the offer. as the ice negotiation use different ports for audio and video seems that if I dont answer with video enable I dont have audio.
> I attach a sip log from asterisk.
> Let me know if Im not clear enough.
