Internet service and VoIP
Considering T Mobile for internet service. I have an elevator that requires a land line. Does the gateway have a port I can plug into for VoIP?

I'm no expert, but my research points to either port blocking or CG-NAT IP addressing. Why it worked for a year+ and then failed is a mystery to me. TM may have rolled out a change, either to my device or to my local infrastructure. With them refusing to even acknowledge the problem, it's impossible to know. Also, the way they they limit your access to the router, diagnosing there is impossible.
Enjoy your TMHI while VOIP works and hope that they don’t screw it up.
