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

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.

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.
