Hi,

I got a new S24 Ultra and the outgoing calls are not working in Viber app(Viber-toViber) on Wifi.
The issue: the call is initiated as it's ringing on the other end but no ringback tone on my phone and all the buttons are greyed out(except 'call end') and the call is not established. It's working fine on mobile data so it must be some kind of issue/limitation for Wifi(I've tried on different wifi networks, mobile hotspot, etc... so it should be something on the phone). Tried with/out 'Wifi calling' enabled, no difference. Incoming calls working fine over Wifi, only the outgoing is failing.

Any idea/advice?

Thank you,
