You need a static PUBLIC IP Address outside any firewall.

The Dynamic DNS sevices require software to run on a PC to work. The Toshiba can't run it. If you had it behind a NAT with software on another PC would work, Except the Toshiba BIPU (and new LIPU) does not work behind a NAT router.

I have installed a Netgear router that ran the client for dynamic DNS services, and created a VPN tunnel. If you had 2 of them, they would create a VPN tunnel, which would solve the problem of being behind a router. You would be limited to the nummber of VPN tunnels you could create.

Other then that, you are pretty much stuck with a static public IP in front of a firewll.

The Software IP works good, but as was said, requires a license on the Toshiba CTX to connect. The BIPU has been discontinued, but I'm sure you can still get it for some time. The replacement, LIPU, would also require an IP endpoint licence for each IP phone. Not sure how much each cost, but a package of 16 retailed for over $1k.

I did not realize that the Toshiba system would not work behind a NAT. I thought the phone system could be set to the DMZ port. Then another pc on my network could have the dynamic ip software.

Any VOIP in general does not work well behind NAT, even using DMZ. I have not heard of anyone getting Toshiba's VOIP to work behind a NAT router. Some people even have a problem with the BIPU behind a firewall (even though Toshiba recomends a firewall).

The IP phones can be behind NAT, but not the phone system, unless you use VPN.

If you are the type of person (like me) that has to know why NAT won't work, look at this

I doesn't talk about Toshiba specifically, but about VOIP and NAT in general

Hey, before you worry about all the small stuff, are you going to buy this much equipment to run a phone?

Have you priced the equipment?

If you are really serious about spending a few grand, then fine, but its more than your 100 so far and if you're not going to spend that, then lets enjoy the system as is.

I just like to know all the options. If I just wanted a boring old phone, then there would be no options. This is much more fun.

Is there any way to get the caller id information to stay on during a call or at least be callable? I set the caller id button, but that only works if the call is on hold.

NewTecky -- FYI..............The BIPU has not been discontinued. It is to be used in the CTX100 and 670. The LIPU is the IP card for the rack mount CIX100/200.

Err... it also works for the CIX 100/670. We have 2 LIPU/S in our 670.

Well, I saw a notice some time ago on Toshiba's website that they were going to stop making the BIPU, but will ship as long as they have stock. The LIPU does everything a BIPU-M and Q does, and more. Bad part is that an LIPU requires an IP license, while a BIPU only needs enough port licenses.

I just put in an LIPU into a CIX-100 (wall mount) yesterday (with the new 4.0 proccessor).
