I'm using an XMPP VOIP app (Cheogram) as my primary calling account/phone number.
The default GOS phone app lets me specify this XMPP account as the default way to make calls by going to Settings -> Calls -> Calling Accounts -> Make calls with.
However, it seems like this setting does not persist after the phone is rebooted.
If I reboot my phone, the default outgoing calling account is reset back to my SIM, which is a phone number I don't give out, so I have to go into the settings and re-enable my XMPP as the default every time.
I've also tried setting "Make calls with" to "Ask First", but this setting doesn't stick either.
Has anyone else had this problem?
