Cisco callmanager auto-attendant

Cisco callmanager auto-attendant allows callers to locate people in the organizaiton without talking to receptionist. You can use the default prompts or customize your own prompts. When an incoming call hits the voice gateway, the voice gateway searches its transfer rules and transfer the call to CUCM, CUCM looks for CTI route points and hands off to Auto-Attendant. Auto-attendant then prompts the options for caller to choose and then transfer the call to the phone accordingly. Here is the diagram for a better understanding.
