Greetings, I am looking for information on your WiFi Calling service. I have scoured the Web to find information but have no definitive document from your support organization that lists out the actual requirements for firewalls to enable WiFi Calling.
This is what I believe from some Web Forums where others have attempted to make this work:
Open the following ports on your firewall to the 208.54.0.1 - 208.54.159.254 T-Mobile servers:
tcp/udp/5061
tcp/udp/5060
udp/40000-59999
udp/4500
udp/500
icmp/unreachable to the TMO2 net range of 208.54.0.1 - 208.54.159.254 (this is used by the client to inform the server that a call has been disconnected by the client).
Is this the correct information? DO you have some type of guide, bulletin or Implementation document that spells out the requirements to enable WiFi Calling for T-Mobile?
Your help would be appreciated.
Thank you, Jim Verlare
