Greetings All,
Currently I'm using GrapheneOS on a Pixel 4 and loving it.
I'm trying to configure Linphone for use with voip.ms so that I can use several phone numbers and selectively turn them off and on when needed. Problem is my outbound audio is often choppy or digitized to the person I'm speaking to.
At first I thought it was the carrier. While switching from Mint (T-Mobile) to Tracfone (Verizon) does give me better quality all around (since Verizon is the dominant carrier in my local area) it's still not there yet.
What I've tried so far:
I've switched to the GSM codec as well as lowering my bitrate, however I've found the lowering the bitrate actually makes it worse, so I switched back to 64Kbps.
I've tried adjusting the ABR setting in Linphone, however this seems to have no effect.
I've tried switching to Sipnetic, bit I never could get it to connect. I also don't like the idea of using something close source.
Is there anything else I can / should try? Am I stuck with using wifi if I want clear calling?
Anxious to hear other experiences with trying to use VoIP if possible.
