I guess it should be 32 seconds known issue in SIP process , in my opinion , you should do double capture between your endpoint and sip server , and find which message lost in process

????: [Linphone-users] Calls hang up after ~30 seconds
Whenever I make a call, the calls hang up after about 30 seconds or so after connecting. Everything else seems to work fine except for this. Any known issues or suggestions as to what it could be? I've used this VoIP/SIP provider with MicroSIP on Windows without any problems but I want to be able to use Linphone on an Android device, and maybe switch to using Linphone on Windows too if I can sort this out on Android first.
FYI: The Android device in question is a Pixel 6A running Graphene OS. It's using the background Linphone services. I tried calling the extension and it rings immediately so push notifications seem to work as intended (I had to give it a bunch of permissions but it wasn't hard to do that).
