I just don't think this whole approach is correct. Essentially the network
is saying "Disconnect and save power" and we are saying immediately "no go
back up again" and this gets repeated every minute. The original patch
simply disguises the reporting. Surely we should be staying disconnected?
Then reconnect when we need to transmit something, and follow whatever the
network will do to start reconnection on an incoming call?

I have tried tinkering in libpri Q921 but I don't really understand how it
works. Should I re-file a bug under LibPri?
