One way audio from sipml5 to freeswich

What steps will reproduce the problem?
1. Register extension from sipml5 through webrtc2sip to freeswitch and it's 
successful
2. Try to make a call from sipml5 to any extension on freeswitch and there is 
one way audio. Audio is only going from sipml5 to freeswich but not the other 
way around, and I see ERRORS on webrtc2sip server. 
3. But if I call from regular sip device to sipml5 , all goes well. Both way 
audio and no Error message on the server. 

What is the expected output? What do you see instead?
I expect to not see errors but I am seeing the following instead:
