Every so often, maybe about once or twice a week, I will encounter this problem where I will make or receive a phone call and the call will sound garbled in general, but voices will sound robotic and unclear. Even the dial tone is garbled. This has happened while calling other mobile phones as well as calling a landline. Every time it has happened, I have been in an area with good coverage, normally full coverage or near-full coverage. If I am streaming music prior to the call, it will be choppy and have streaming issues when I end the call. The only method I have found to resolve it is to restart my phone, which is not an ideal experience.
Has anyone else encountered this issue? I never experienced this when I was previously on the AT&T network and I'm concluding it is probably a network issue rather than a device issue, however I haven't ruled out either as a possibility. My device is a Moto G4 Play, which hasn't had any problems since I got it.

I haven't encountered it for a about a week; it had been a few days since it last happened when I posted the original question. As for the questions posted above, I haven't been able to figure out a pattern. The few times it had happened I was driving and my phone was connected to my car via bluetooth. I was in different locations, only separated by a few miles, and with high coverage. In two instances it occurred while connecting to a mobile phone not on the T-mobile network and another time it occurred while connecting to a land-line.
I've been unable to reproduce the problem consistently, and since it has only happened while in my car, I usually just stop trying to make the call until I can restart the phone. I can try airplane mode next time it occurs. Come to think of it, may it be possible that something in my car is messing with my signal? I've noticed the GPS has issues finding my location and updating while doing direction, but I just figured it was the device itself.
