To try to explain:
The phone system is not using SIP it is using a proprietary protocal.
We are a small company - We have a cable internet connection with a Cisco PIX (in our main facility)connected as our gateway. Currently we have one Stat IP address. Then that feeds our electronic switch. The servers are connected to the switch. Our new phone system also connects to the switch for backup and phone system management. There is only one (right now) VoIP phone that is located 2000 miles away that we would like to connect to the new phone system as thought thie VoIP phone was an extension on our local phone system. Technical support from the phone provider now indicates that if we have a "2nd Static IP and can pass that IP through to the phone system (locally) that is all they need and the guarantee that the VoIP phone will operate from any internet connection without a tunnel. I have procured a 2nd Static IP address and I would know like to forward the 2nd Statip Ip through to the Phone System. Let me know if this sounds possible and what instructions i need to change on the Cisco Router to accomplish that.
Thanks in advance.
