Our office is moving and we decided to change our VOIP infrastructure. Currently we have our Call managers passing the traffic to our router in the office. However that ISP is going to install a router at our office that will handle the VOIP to outside world. I need a configure our router which is currently handling the VOIP traffic so that it passed the VOIP traffic to the ISP's router. We do not have any routing statements that tell the router to forward the call to the PRI, so I don't know how to setup a forwarding from our router to theirs. Our call managers are in our office. Thanks for the help.
