I tried to flip the switch on the Lineage ROM but it was grayed out in the off position. After reflashing stock, I could flip the switch on and the stock ROM worked fine. Flashing Lineage after that, the switch is still grayed out and unflippable but it is now stuck in the on position. Receiving calls on the Lineage ROM started working with the grayed out switch now turned on though. Data and everything else works fine.

I understand and appreciate that. I'm still learning about the phone as I've only had it this week. On the Lineage ROM, I can't make any calls out, but I can on the stock ROM. On both ROMs, I can receive calls fine. The HD symbol appears on the screen when I have a call up on the Linage ROM, FWIW. I forget if the stock ROM also displayed the HD symbol. The phone is setup for "LTE only", so I assume it has to be using VoLTE. Whenever I try to make a call out with the LIneage ROM it just immediately disconnects. So I'm not sure if VoLTE has something to do with it or not, just suspected

I apologize for stating incorrectly the phone does not support CDMA. For the topic of this discussion however, the main point is everything works on the stock ROM, but I can't make outbound calls on the Linage ROM.

Like everyone here, thanks to @tdm very much for working on Linage for our phones. I used to use it on my Photon Q for years and missed it when I went to the Z for the keyboard mod. I am having a problem with being able to make phone calls. I can receive them fine and can also send/receive SMS/MMS. I'm on Verizon in the US, and since this phone apparently doesn't support CDMA, VoLTE must be used. I couldn't get it to work at all until I reflashed the stock build and turned on the Voice over LTE switch under the test screen (*#*#4636#*#*). Then I flashed Linage test2 again and it
