We just purchased a Toshiba CTX670 with the VOIP card. Our provider isn't much help at all. Like others have said, they claim you just plug it in and it should work.

I'm curious as to where you change the codec. We have the WinAdmin software but I haven't seen that setting anywhere for the VOIP card. Is there another way to configure the card?

We connect our VPN via Windows XP. How would you use the phone over a VPN connection?

#1 - VPN on WinXP is just computer to computer, not a true network-wide VPN. Your VPN needs to include the IP of the VoIP card and the IP phone. I would suggest using a VPN router, Linksys and Netgear make affordable ones.
#2 - All the settings for VoIP are listed under "IP Telephony", not under card or station programming. Definitely use G.729 codec, MH216 or later software on the CTX, and increase the jitter buffer. If you or your provider needs help configuring VoIP, send me an email or reply here.

Junkman: Thanks for the quick response.

Overview: We hope to implement VoIP phones for 5 of our remote employees. They are located in different states and one is in Canada.

I have successfully got one VoIP phone working on the internal network. It works great. My next task to get another VoIP working from my home DSL connection. From doing a little research I have found I have the following options to achieve this.

1. Get a VPN router for each location.
2. Put the VoIP card outside of the firewall (I prefer not to do this – Any thoughts?).
3. Open the correct ports on the firewall allowing the VoIP traffic to reach the card. (I haven't been able to find the port numbers to try this).

Have any other suggestions?

The official word from Toshiba is that the BIPU Card Will not work behind a firewall. It has to go outside with a public IP. There are no security concerns. I have done this at various locations with no problems. The IP phones WILL work behind your firewall at home. My experience is that a linksys DSL router works out of the box. The Netgear needs to have the ports opened. I have that port information if you need it. E-mail me.

I was going through the settings in the Network Setting Mode on the IP phone (IPT2020). What are the purposes of the following settings?

1. Default Router Address - This is typically assigned by DHCP or should I put one in? Should this be the IP address of the linksys/netgear router?

2. Admin IP Address Lower/Upper - ?

3. PASSWORD(Within 16char) - Can I assign a password at the PBX level so only phones with the correct password can connect?

Router address should be assigned by DHCP or you can manually enter the address of your router. Not familiar with the 2020, so I don't know about the other 2.

Heres my experience......

1. The router address (default gateway) is assigned by DHCP. If you are using a Netgear wireless router, you may have to assign a static IP, Subnet mask and gateway to the phone.

2. I don't know what you mean here. DHCP will assign the IP for the phone. On button (I think 12) is where you have to enter the IP address of your BIPU card.

3. I don't believe so. Anyone who knows the IP for the BIPU will be able to connect if there is an IP port programmed and noone is using it. For example, I have an IP phone here. If you have an extn 501 programmed on the BIPU and noone is connected to it, I can enter it here and use your system. The only thing you can do is toll restrict the port, assign forced account codes or delete the port.

Thats the way I understand it.
