Three blocking wifi calling via another provider

[Dazzar]

Along with the issue over sky glass not working I am now finding out that using their 5g router I cannot make wifi calling from phones with Vodafone as the service provider , has anyone else had this issue…..

Hey @Dazzar, what happens when you try to make a call from a Vodafone SIM, while connected to your Three home broadband?

Are you hearing an error message or does the call simply not connect? 

Can you make Wi-Fi calls using the Vodafone phone when connected to an alternative Wi-Fi signal?

The calls just drop out
