As far as signalling is concerned between the bank and the IVR server. I am not aware of any signalling going on in that regard. The thing is the IVR server is actually just an external modem bank. The bank holds 12 external modems. Basically, I just want to route call through the channel bank to the modem bank. That's it. That's what I want to accomplish.

So what do you think? Do I need to go about this a different way? Need more equipment?

I'm open to suggestions
Thank You
