Poor quality of outgoing calls (voLTE, voWiFi) on ZENFONE 8; cutting words, robotic sound

[arielsajda]

Hi,
when I call via voLTE or voWiFi and someone picks up, the call sounds good, but after a while it starts to sound very bad. When I answer (even one word), it's ok again (listening to the interlocutor) for a while, and then the same... I barely can understand words.
Other users with ZF8 has same issues.
voLTE and voWiFi - the same issue. The signal is full... T-Mobile PL, and WiFi 600Mb/s.
I'm on latest release *.89

Me too, other phones works perfectly.

Problem aktualnie jest u mnie z T-Mobile w regionie. Wyłączyłem VOLTE, testuję jeszcze WiFi Calling...

Hey, any news? The issues are really disappointing 😞 I'm working a lot while calling on loudspeaker. I need data durring calls and but voLTE/voWiFi calls quality are unnaceptable and this echo on loudspeaker for listeners...
