Just following up, I still haven't been able to solve this issue. The little hack that I've done is when you answer a call on the device it immediately places...

Still trying to figure it out. I feel like it has something to do with RNCallKit but unable to prove it yet as it doesn't happen on my iOS Simulator...

Also on the person who cannot hear the audio, try placing the call on hold and resuming and see if that activates the audio.

Can you test the hold and then un-hold from the iOS app and see if that fixes the audio? I'm just trying to see if the issue is consistent. Let...

Just using: `endpoint.holdCall(call)` and `endpoint.unholdCall(call)`. That's also assuming that your SIP server supports placing a call on hold. Are you using the PjSip App (https://github.com/datso/react-native-pjsip-app/)?

This is just a test by the way, it's not a real fix... Let me know if it resolves the audio issue though. I'm also not 100% sure if RNCallKit...

I've tried a similar solution to that before with the activateAudioSession and it doesn't appear to fix it. If you keep testing it you'll find that it is still broken...

Receiving calls on LTE work just fine. Anyone else have this problem? The outbound LTE calls work fine on other apps like CSipSimple and Zoiper without any NAT settings enabled...

It works for some LTE networks but not for others. I haven't spent much time into finding a solution as of yet.
