Examples
For the following configuration, if the voice-mail number is 1101, and 3001 is a phone with a message
button, 1101*3001 would be dialed automatically when the 3001 message button is pressed. Under these
circumstances, 3001 is considered to be a calling number or inbound call number.

pattern direct * CGN
For the following configuration, if 3001 calls 3006 and 3006 does not answer, the SCCP SRST router
will forward 3001 to the voice-mail system (1101) and send to the voice-mail system the DTMF pattern
# 3006 #2. This pattern is intended to select voice mailbox number 3006 (3006’s voice mailbox). For this
pattern to be sent, 3001 must be a forwarding number.

pattern ext-to-ext no-answer # FDN #2
For the following configuration, if 3006 is busy and 3001 calls 3006, the SCCP SRST router will forward
3001 to the voice-mail system (1101) and send to the voice-mail system the DTMF pattern # 3006 #2.
This pattern is intended to select voice mailbox number 3006 (3006’s voice mailbox). For this pattern to
be sent, 3001 must be a forwarding number.

Configuring Message Waiting Indication
The MWI relay mechanism is initiated after someone leaves a voice-mail message on the remote
voice-mail message system. MWI relay is required when one Cisco Unity Voice Mail system is shared
by multiple Cisco Unified SCCP SRST routers. SCCP SRST routers use the SIP Subscribe and Notify
methods for MWI. See
Configuring Cisco IOS SIP Configuration Guide
for more information on SIP
MWI and the Subscribe and Notify methods. The SCCP SRST router that is the SIP MWI relay server
acts as the SIP notifier. The other remote routers act as the SIP subscribers.
