I have this issue on both phones I have. WiFi Calling Enabled or not, even with 3-4 bars LTE. I can talk to anyone without issues but the other phone on XM. If either phones calls the other, the call will drop after 3 to 9 seconds. Perfect clarity in that time before the call “failed”. Have any actual solutions been found besides going to a different carrier? Issues have happened since Day 2 of switching to Xfinity last weekend. One brand new iPhone XR, one unlocked iPhone 6S Plus. Phones are both up to date. Only 3 calls have lasted longer than 9 seconds out of 51 tries. Both phones have been shut off multiple times. Airplane mode cycled. WiFi calling cycled. Roaming cycled. No luck in replicating any success.
