The customer is replacing their voice-mail system with a Cisco Unified Messaging system. They have 1400 employees at their headquarters location, and 800 employees spread out over 80 branch locations. They have recently deployed a Cisco Unified CallManager cluster at the headquarters location that provides centralized call processing for the branch locations.

The customer has an existing phone system that will be phased out slowly, but for now they need one voice-mail system to support both the existing phone system and the Cisco Unified CallManager. The existing voice-mail system is used for both voice mail and Auto Attendant functions. The existing system has 36 ports.

Thirty-two ports are used for Auto Attendant and voice mail. The last four are used for dial-out notification. The Auto Attendant provides outside callers with a menu of options that allows their call to be routed to a department. While each subscriber greeting is played, the caller is offered the option to “press 1 to page this person now.”

The old voice-mail system would then ask the caller to enter the number at which the caller can be reached and then page the subscriber with that number. The caller can press 0 and be routed to the operator for that department. When a caller chooses either the sales or the service department, the caller is sent to a queue for the next available person in that department. Managers can also modify the Auto Attendant greetings to play different prompts by dialing into the main Auto Attendant number.

A.
model and version of the existing phone system

B.
Cisco Unity cannot queue callers for a busy extension.

C.
Auto Attendant greetings cannot be changed over the phone.

D.
The paging feature described is not available with Cisco Unity.
