Cisco IOS Telephony Service, Version 2.02
Chapter 4 Advanced Configuration Tasks
Integrating Voice Mail
Configuring a Directory Number for MWI Notification
MWI integration on the Cisco IOS Telephony Service router is performed by dedicating Cisco IP phone
DNs (ephone-DNs) to process MWI status notification calls originating from the Cisco Unity Voice Mail
system. You must allocate a minimum of one MWI processing ephone-dn for each MWI ephone-dn
access port. The MWI processing ephone-dn extension numbers are configured to match the MWI
dial-out notification numbers configured on the Cisco Unity Voice Mail system.
SUMMARY STEPS
1. ephone-dn dn-tag
2. number number [secondary number]
3. mwi {on | off | on-off}
DETAILED STEPS
Step 3
Router(config-ephone-dn)# name name
Configures a username associated with a directory
number to receive MWI notification.
For example, “MWI” is used in place of the name
argument.
Step 4
Router(config-ephone-dn)# mwi sip
Subscribes an extension in a Cisco IOS Telephony
Service router to receive MWI notification from a SIP
MWI server. This integrates a Cisco IOS Telephony
Service router with an MWI service based on SIP
protocol.
Note The mwi sip-server command under
telephony-service configuration mode should
be set prior to enabling the mwi sip command
in ephone configuration mode.
