Currently we are running CallManager 4.1(3)sr3 along with Unity 4.04.
We currently are using MGCP to control all of our gateways from a
centralized cluster and utilize SRST at remote sites for failover. I
was wondering if anyone has been successful, while in SRST mode, of
redirecting an inbound call after a set amount of rings to their
voicemail server, and have the subscribers message play rather than the
main Unity greeting. We are using ISDN PRI at our remote sites. I know
that there were some commands that you could configure to send digits to
the Unity server, but from what I understand those were only supported
in a analog configuration.
Below is a excerpt of my call-manager fallback config:
call-manager-fallback
voicemail 91517xxxxxxx
call-forward busy 91517xxxxxxx
call-forward noan 9517xxxxxxx timeout 12
Any help would be greatly appreciated.

Hello John,
Your call-forward noan is set to 9517xxxxxxx. Is that correct, or should it be 91517xxxxxxx like the voicemail setting as well as the call-forward busy?
Debug isdn q91 may be useful to help pin-point why your tests are failing.
Regards,
Michael.

You need to ensure that RDNIS is suppored on your carrier, then you need to ensure that GW at the head end site is configured to inspect RDNIS by checking the "Redirecting Number IE Delivery - Inbound" field. If you are not using 10 digit dial plan, you need to configure your subscribers with a matching 10 digit alternate extension as well.
Your debug isdn q931 on both sides will indicate if RDNIS is sent and received.

Is there any workaround if RDNIS is not working on the PRI? What are some of the workarounds that I have if RDNIS is not a option? Any suggestion would be appreciated.
thanks

You can do FXO integration.

Try putting this command under the PRI interface.
