Here is my situation. I have one incoming Vonage voip line. It comes in through a cable modem. I want to set up a PBX type arrangement where people calling in can press 1 for person a, press 2 for person b and so on. When they press one or two I want it to forward that call to an outside line. Will Asterisk take one incoming Vonage line, and forward it to different cell phone numbers depending on who they chose to speak to. Is this possible? If not with the arrangement I have now what would I need to make this possible?
