Configure

Voice mail configuration consists of these steps:

1. Configure Voice Mail Ports in Unified CallManager (as described in Unified CallManager Voice Mail Interactive Voice Network Configuration Example)
2. Configure Message Waiting (as described in Unified CallManager Voice Mail Interactive Voice Network Configuration Example)
3. Configure Voice Mail Pilot (as described in Unified CallManager Voice Mail Interactive Voice Network Configuration Example)
4. Configure Voice Mail Profile (as described in Unified CallManager Voice Mail Interactive Voice Network Configuration Example)
5. Configure Line Group (as described in Unified CallManager Voice Mail Interactive Voice Network Configuration Example)
6. Configure Hunt List (as described in Unified CallManager Voice Mail Interactive Voice Network Configuration Example)
7. Configure Hunt Pilot (as described in Unified CallManager Voice Mail Interactive Voice Network Configuration Example)
8. Configure Gateways to Enable Redirecting Number IE Delivery (as described in Unified CallManager Voice Mail Interactive Voice Network Configuration Example)
9. Integrate Unity, Add Subscribers, and Configure Alternate Extensions (as described in Unity Voice Mail Interactive Voice Network Configuration Example)
10. Verify Phone DNs Include Correct Voice Mail Profile (as described in Phone Configuration (San Jose) Interactive Voice Network Configuration Example)
11. Configure SRST to Forward Calls No-Answer to Voice Mail
12. Verify the Voice Mail Configuration (as described in Voice Mail Interactive Voice Network Testing and Verification)

This document describes step 11. For information about the other steps in this procedure, refer to the appropriate documents.

Configure SRST to Forward Calls No-Answer to Voice Mail

In order to allow SRST user access to voice mail, configure these parameters on the SRST gateway:

call-manager-fallback
:
:
dialplan-pattern 1 9195014... extension-length 4
voicemail 914085011600 	 !--- Enables SRST users to check their voice mail box
call-forward busy 914085011600 !--- 1600 corresponds to the pilot number for Unity
                               !--- configured in Unified CallManager
call-forward noan 914085011600 timeout 10

Note: This example includes the full E164 number (which includes 9) and assumes the PSTN delivers full 10-digit numbers.

Configure Alternate Extensions

The calling number is determined based on how your dial plan is configured. In this example, when the remote branch router fails over to SRST, the full E164 number is sent as the calling number for voice mail calls. When Unity receives this number, it generate the general Opening Greeting announcement (and does not prompt the user to enter their PIN number to sign in).

In order to prevent this situation, configure alternate extensions for users with the full E164 number. For more information, refer to Voice Mail Interactive Voice Network Testing and Verification.
