I am trying to figure out the relations between IVR port verses CTI port and CMT channel. I have IPCC Premium with 300 IVR ports. My understading is that when a call is sent to a route point, IPCC uses 1 IVR port for the CTI port to process the call. Once the call goes thru a script I understand it requires a CMT channel to collect DTMF digits. Does a CMT channel use up another IVR port? Does that mean it requires 2 IVR ports minimum per each call?
