O2 WIFI Calling destination IP addresses

[ag005613]

Hi,

Am looking for information please - for setup in corporate network. Our firewalls appear to be blockimg wifi calling. Can you please advise what ports and destination addresses need to be added to the firewall rules?

@Chris_K is no longer with us @NorfTyrone 

@Dave-O2 might be able to help though.

That looks like a port forwarding rule and not a firewall wall. 

Who is your ISP, and what issues are you seeing when trying to use WiFi Calling..  

Don't take this the wrong way but if you don't know what these things do, then don't change them, as you could lose internet access, and break other things.

Hi- Yeah, totally understand where you're coming from. I am reticent to try/ change anything as it's not my area of strength.

However, as I've no mobile signal at home, and BT not able/ willing to help, I am cornered. I am going to borrow a hub over the next day or two which I hope will fix the issue. At least then I can go back to BT with that info.

Thanks
