SIP Trunking


Badge

I tested this service in January and discovered that I could not register SIP trunks using the 5G, I called the tmobile tech services and was informed that they were aware of this. I returned the equipment. Has this problem been solved, as I was very please with the other testing.

One of the down-sides of Home Internet is that the connection is totally firewalled and NATed.

The router, the network, the whole ball of wax. It’s like cellular internet on steroids. There’s no way to get into a Home Internet connection from outside. Take my AT&T Uverse for example, I have a real, though dynamic, IPv4 address. If I open a pinhole in my personal firewall, I can run a VPN server (which I do). I could run almost any type of server (e.g. Web, VoIP, IMAP, game, etc) if I wanted to. No one’s figured out how to do that with Home Internet. It’s sort of crippled. It can be great if all you want to do is run as a client but that’s only half of what an Internet connection is for.

A SIP client is a difficult enough proposition in the face of a single NAT and a firewall. Multiple NATs, firewall. I have no idea how one would make a server work.
