Same problem I've been experiencing lately, the dialer display never changes over to the call display. The call briefly gets made but immediately terminates with no audio. Dialing from the address book works a little bit better but still buggy, frequently requiring several attempts. Frustrating since making calls was solid a few months ago.I'm going to say this and you may not like it. What it sounds like you are experiencing is an AT&T VoLTE problem. It's a problem you have when you are on band 12 AT&T. You would have data but can only make calls with VoLTE. AT&T has VoLTE turned off for you or is not supporting your device on its back end. Band 12 has no legacy 2G and 3G fallback for calling like AT&T LTE bands 2,4,17. If you are on LTE band 12, and that is the primary band now outside of the big cities due to its long range and its roaming agreements with T-Mobile, calls will only go through on VoLTE so your calls would fail like you are describing. The bad news is it's only going to get worse as time goes on as all calls will eventually go through VoLTE (with all carriers) as they switch over to VoLTE only over the next year. You might want to consider trying another carrier to make sure. Buy a cheap prepaid T-Mobile sim and see if that works and that will confirm it. I will say I have had no problems with T-Mobile on the Pinephone but have experience with what you are going through when T-Mobile switched to band 12 three years ago and devices I owned were not certified by T-Mobile on their network for band 12 even though they had band 12 radios. Google Pixels, Nexus 5X and 6P using Fi (a T-Mobile MVNO). Eventually Google worked it out and they did get certified and T-Mobile turned on VoLTE on the back end and they worked but it took a year. AT&T is very controlling of devices on their network. More so than any other carrier right now.
As far as MTP, I was wondering what happened. Previously if the Pinephone's USB cable was plugged into a Linux computer files could easily be copied back and forth. (Files copied to the phone would be owned and accessible only by root but "sudo chown -R" easily fixed that.) Today I had some files to transfer and thought I'd do it that way but of course it didn't work. (I used sshfs instead.)
Hopefully these regressions will be fixed in the near future.
