DETAILED STEPS

Configuring the Router for Cisco Unity Voice Mail

To configure a voice-mail system on a Cisco IOS Telephony Service router, you allocate and configure

one or more Cisco IP phone DN to link your Cisco IOS Telephony Service router to your voice-mail

system. Use a Cisco IP phone DN and configure it with the same access number for the voice-mail

(configured in telephony-service configuration mode), for example 4001. This configuration is required

for all voice-mail system integration, including Cisco Unity Voice Mail.
