WiFi calling no sound

[Mikel]

For at least the past couple of weeks, when I receive a call, I can't hear anything at all.

I have an ASUS Zenfone 9.

Looks like this has happened on O2 previously with other devices. Can someone please check the current status?

I would reach out to Asus and ask them if there has been an update to the phone that affects WiFi calling, as it is usually updates that break it.   

This also isn't CS so you would have to call Customer Services or drop them a message on Social media,  on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG), or you can call 202 from your o2 phone
