iOS Phones no audio on 3/4G
Our IR has a new installation with RB and WebRTC GW on miniPc. When customer is out of WiFi connection RB application runs OK on 3/4G on Android devices, but not on iPhone, i.e. there is no audio but signalling works OK.
Is there any known problem around iOS devices in similar cases?
After reading your message I also tried a series of WebRTC calls on my iPhone and also had the same issue as you - no speech path.
One thing that I have discovered is that when there is a major Rainbow update, a new OXO version update or a WebRTC software update, I sometimes get issues like no speech path.
Quite often, if I logout of Rainbow on my iPhone and close the Rainbow application and even turn the iPhone off and back on - it seems to fix these issues.
I can confirm that after I did these things this morning - the WebRTC function on my iPhone was working correctly again and I had speech path. I tried a variety of calls - iPhone Locked, iPhone unlocked - Rainbow closed, Rainbow open and they all worked after I turned my iphone off and back on and logged back into Rainbow.
I hope this works for you as well.
