Firewall rules for WiFi Calling (UK)

[deanturner95]

Hi guys,

I need to allow WiFi Calling through a firewall appliance, can anyone tell me or link me to where to find the ports used and IP ranges I need to allow.

Cannot find documentation Anywhere online.

Cheers

Hi,

Is this Vodafone Calling Over Wifi on a mobile phone. 

Vodafone Calling Over Wifi.

This is not what I'm looking for. As I have said, I am looking for the ports and IP's used so I can create an exception in a firewall configuration.

You'll ned to explain what you are trying to achieve if it isn't relating to Wi Fi calling on a mobile phone.

For apple phones they say  UDP 500/4500

This is a RFC and standard so I would expect it is the same ports for all providers.
