I have confirmed these applications will allow you to use VoIP via your LTE connection as a bandaid till VoLTE is released. Both can be found in Aurora and are a “quick fix”. If someone is on T-Mobile the “DIGITS” app is included with their subscription already at no additional cost. With the magicApp you can buy the hardware for home VoIP & a 12 month subscription for the same price as just the app via G*#gle Play(for 12months) and not have to login to the Gapp store or give them a commission. My advice is to buy direct if going this route, not via GPlay store.
For non-FOSS apps having only 1 or 2 trackers was surprising to me. We know how to block these if they are “non-essential” obviously. The permissions… Another story but these apps are managing calls and SMS/MMS so a bit more understandable.
Exodus Analysis:
magicApp Calls/SMS only
DIGITS Calls/SMS/MMS

*Edit: the T-Mobile digits app is now reverting to the default dialer and not allowing VoIP (I swear it wasn’t doing this at first but maybe I am wrong. magicApp is functioning VoIP over LTE connection.)
