wifi calling worked at work on android phone but not on new iphone

[Bazza3]

Hi,

Where I work there is no mobile phone signal and I rely on wifi calling over the corporate wifi.

I had an android phone and had no issue with wifi calling but I recently switched to an iphone SE (2022 3rd gen) and it will not work with wi-fi calling on the work wifi network.

Wifi calling works with no issues on my home broadband network so theer are no issues with the account or phone setup.

The IT support have had a look and can find no problems, the ports for O2 wifi calling are all enabled in the network and other users on O2 are working ( including my previous android phone ) and they have run out of suggestions.

Is there any know differences in iphone vs android on O2 that could be causing this ?

Wifi calling should be the same on both.

On O2 the only difference is iData needs to be added to your account for iMessage and Facetime to work, but I've not heard of it messing with WiFi Calling
