AT#ATDCECHECK=<enable>
Execution command enables/disables checking of CAT-M1 CE Mode A
level before starting a VoLTE call; if check is enabled, VoLTE calls will not
be attempted when CE level is 1. There is nothing in the standards that
prevents the UE from setting up a VoLTE call while in CE mode, but in
Level 1 it will fail: the network will try to allocate resources and set up the
call, but the link will not support a bearer with the required throughput
and latency requirements for VoLTE, so even if the call setup succeeds,
voice will be unintelligible, and the link will eventually fail (drop).
