Redirecting to Cisco Unified CallManager Gateway
Note The following task is required for voice-mail systems with BRI or PRI access.
In addition to supporting message buttons for retrieving personal messages, Cisco Unified SRST allows
the automatic forwarding of calls to busy and unanswered numbers to voice-mail systems. Voice-mail
systems with BRI or PRI access can log in to the calling phone’s mailbox directly. For this to happen,
some Cisco Unified CallManager configuration is recommended. If your voice-mail system supports
Redirected Dialed Number Identification Service (RDNIS), RDNIS must be included in the outgoing
SETUP message to Cisco Unified CallManager to declare the last redirected number and the originally
dialed number to and from configured devices and applications.
Step 1 From any page in Cisco Unified CallManager, click Device and Gateway.
Step 2 From the Find and List Gateways page, click Find.
Step 3 From the Find and List Gateways page, choose a device name.
Step 4 From the Gateway Configuration page, check Redirecting Number IE Delivery - Outgoing.
Configuring Call Forwarding to Voice Mail
Note The following task is required for voice-mail systems with FXO or FXS access.
In addition to supporting message buttons for retrieving personal messages, Cisco Unified SRST allows
the automatic forwarding of calls to busy or unanswered numbers to voice-mail systems. The forwarded
calls can be routed to almost any location in the voice-mail system. Typically, calls are forwarded to a
location in the called number’s mailbox where the caller can leave messages.
