Examples
The following FXO and FXS example sets up a POTS dial peer named 1102, matches dial-peer 1102 to
voice-mail extension 1101, and assigns dial-peer 1102 to voice-port 1/1/1 where the voice-mail system
is connected. Other dial peers are configured for direct access to voice mail.

Configuring Message Buttons
To activate the message buttons on Cisco Unified IP phones connected to the Cisco Unified SCCP and
SIP SRST router during Cisco Unified Communications Manager fallback, you must program a
speed-dial number to the voice-mail system. The speed-dial number is dialed when message buttons on
phones connected to the Cisco Unified SCCP and SIP SRST router are pressed during Cisco Unified CM
fallback. In addition, call forwarding must be configured so that calls to busy and unanswered numbers
are sent to the voice-mail number.
This configuration is required for FXO or FXS and BRI or PRI.
