Chapter 6 Integrating Cisco Unity with the Phone System

Centralized Voice Messaging

•The unique subscriber extensions on the non-integrated phone system to forward on no answer to the corresponding phantom extensions on Cisco Unified CM.

•The Switch.ini file (phone system configuration file) to enable Cisco Unity access through the serial cable for turning alternate MWIs on and off.

•An RS-232 serial cable between a Cisco Unity serial port and the non-integrated phone system serial port to send alternate MWI activation requests.

•The Cisco Unity serial configuration file, if the non-integrated phone system uses a serial configuration different from the default serial configuration used by Cisco Unity.

Figure 6-17shows the connections via a serial cable between a Cisco Unified CM integration and a non-integrated phone system.

Centralized Voice Messaging

Cisco Unity supports centralized voice messaging by supporting various inter-phone system networking protocols including, for example, proprietary protocols such as Avaya DCS, Nortel MCDN, or Siemens CorNet, and standards-based protocols such as QSIG or DPNSS.

When discussing phone systems involved in centralized voice messaging, there are essentially two types:

Message Centre PINX	The phone system hosts the voice messaging system (the phone system is
	directly connected to the voice messaging system).
Subscriber PINX	The phone system is remote from the voice messaging system (the phone system
	is not directly connected to the voice messaging system).

Centralized voice messaging provides voice messaging services to all subscribers in a networked phone system environment. Cisco Unity can be hosted on a message centre PINX and provide voice messaging services to all subscribers in an enterprise assuming the message centre PINX and all subscriber PINX phone systems are properly networked.
