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

I did the update to version .122 and enabled wifi calling and volte but it still doesn't work. When wifi calling was enabled I had to accept the "terms and conditions" but the Vowifi icon is not displayed and calling with airplane mode on and wifi connected doesn't work. When I try to make a call, a message to connect to wireless network appears. I'm connected to a wifi with Internet connection... Tried restarting a couple of times.
I wonder why it works for you but not for me 😞

Try restarting voLTE button once again. After turning it on wait a few seconds then check the notification bar icon. You have to have LTE data turned on obviously.

I tried that and unfortunately I don't see any change on the notification bar when I disable/enable VoLTE . I also tried calling someone to see if anything changes but it's the same as it was before enabling this option..

Mobile data turned on? If these settings are not working then I don't have an idea how to help You 😞
