I need some help selecting the appropriate hardware for a VoIP solution. I am a totally new when it comes to VoIP so please take baby steps with me. (Sorry for the long note but I want to explain it as best as possible.)
We have a predictive dialer system (outbound only). The T1 lines (PRI T1) connect directly from the smart jack to a board on the dialer. Analog extensions are wired off the dialer to a huge phone block and out to dedicated stations. Each station represents an extension (extensions do not float, in other words if I sit at a station I know I am extension XYZ off the dialerâ¦hardwired (it could be different but this is the basic set-up). The dialer will make outbound calls and once it connects to a live person it will route the call to a particular extension (knowing that the station is ready to receive a call because the station has signed on (to sign on, the person at the station just takes the phone off-hook, the dialer sends a pulse tone on the line and when it has a call it sends it to the extension). Basically the dialer is a PBX of sorts.
What we want:
We would like to design a VoIP solution for the dialer extensions. We would like to have an extension be at any location (outside the LAN/WAN). For our current scenario, all the âremoteâ extensions would be offshore (outside the USA) and be designed in such a way that a VoIP connection would connect to a particular extension on the dialer.
What type of hardware would we need (please be specific)? I presume we would need a VoIP gateway where all the analog extensions from the dialer would plug into it? And this is where I don't understand thingsâ¦ then we would have IP phones that connect to VoIP gateway (to a particular port so we know that VoIP connection X is connected to dialer extension Y). OR would we have another device located at the offshore location that coverts the VoIP back to hardwire and out to a station. The most ideal situation would be just having 1 VoIP gateway and then connections made to it from any location. What would work best?
