Cisco Systems EGW 2200 manual Integrations with Multiple Phone Systems, Field Considerations

QSIG/DPNSS Phone System with Cisco EGW 2200 Integration Guide for Cisco Unity Connection 1.1

Planning How the Voice Messaging Ports Will Be Used by Cisco Unity Connection

Identified user messaging	Cisco Unity Connection automatically identifies a user who leaves
	a message during a forwarded internal call, based on the extension
	from which the call originated.
Message waiting indication	When a message is waiting for a user, Cisco Unity Connection
	notifies the phone system to activate the message waiting indicator
	(MWI) on the user extension.

Integrations with Multiple Phone Systems

Cisco Unity Connection can be integrated with multiple phone systems at one time. For the most recent information on and instructions for integrating Cisco Unity Connection with multiple phone systems, refer to the Multiple Phone System Integration Guide at http://www.cisco.com/en/US/products/ps6509/products_installation_and_configuration_guides_list.ht ml.

Planning How the Voice Messaging Ports Will Be Used by Cisco Unity Connection

	Before programming the phone system, you need to plan how the voice messaging ports will be used by
	Cisco Unity Connection.
	Unlike other integrations, the hunt group mechanism for a QSIG/DPNSS phone system integration is
	implemented on the Cisco Unity Connection server. Within a port group, each incoming call hunts for
	an available voice messaging port among all the ports in a round-robin (or circular) fashion. If a voice
	messaging port in the cluster is set not to answer calls or is not enabled, a call reaching that port may
	receive a busy signal.
	Table 1 describes the voice messaging port settings in Cisco Unity Connection that can be set on
	Telephony Integrations > Port of Cisco Unity Connection Administration.

Field		Considerations
Enabled		Check this check box.
Answer Calls			Check this check box.
		Caution All voice messaging ports connecting to the phone system must have the
				Answer Calls box checked. Otherwise, calls to Cisco Unity Connection may
				not be answered.
Perform Message Notification		Check this check box to designate the port for notifying users of messages.
Send MWI Requests		Check this check box to designate the port for turning MWIs on and off.
Allow TRAP Connections		Check this check box so that users can use the phone as a recording and playback device
		in Cisco Unity Connection web applications and e-mail clients.

The Number of Voice Messaging Ports to Install

The number of voice messaging ports to install depends on numerous factors, including:
