I have updated from lineage-16.0-20191126 to lineage-16.0-20200411. People tell me on whatsapp video calls that they hear echo of themselves since the update. Do you have this problem?

Does Voice over LTE (voLTE) work correctly?

Hey there!

I cannot get voLTE to work correctly in my x720.
When calling certain landline numbers and voLTE is enabled in the settings, the call will terminate instantly stating a server error.

Calling mobile numbers and most of the landmine numbers works though. I live in germany and am using O2/Telefónica carrier..

I guess it is just me having this problem?
Maybe it is a modem/Firmware Problem?
Any help would be aprecciated.

I'm on the last version of LOS16 dated April 18th 2020. Everything worked fine until a couple of weeks ago when I started experiencing no voice on calls. I can't hear the other party and they can't hear me when I initiate the call. Everything works well when I get calls or when I use Whatsapp or other VoIP apps. I'm using the built in phone app and made no changes to the phone since April last year, save for updating the apps through Google Play.
