A CT) route point is a virtual device that can receive multiple simultaneous calls for application-controlled redirection.
Multiple simultaneous users can dial the number assigned to an application such as IP AA, IVR or Cisco SoftPhone etc and have their calls routed to a user's extension or the Operator's phone. Applications that use CTI route points and CTI ports include Cisco SoftPhone, Cisco IP AA, and Cisco IP IVR
The Route Point and CTI Ports behave like a hunt group. A call comes into a single number and is then handed off to another phone (CTI Port) for additional processing.
This frees up the original number to accept the next call. If the CTI Route Point has an available CTI Port, the call is handed off to that port. Otherwise the call cannot be handled. The CTI Port then handles the call and forwards it as necessary.
The folowing document shows a configuration example using the application Cisco IP AA:
