I need to provide local voicemail/auto attendant during SRST in the event of a WAN outage. The customer has Exchange at both the main site and the remote site which forced us to go with two Unity servers, each co-located with their subscribers message store. During a WAN outage, I lose all voicemail and auto attendant functionality. I could configure the TCL script for the AA part, but lack of voicemail is the big hurdle I am dealing with. I cannot use RDNIS to have voicemail failover to the main site since the subscribers reside on the remote Unity server. Having a separate subscriber at the main site for the entire remote office during the outage is also not an option.
Is there any way to configure some of the ports on the remote Unity server to connect to the SRST gateway - either SIP or SCCP - to handle calls in SRST mode? This would be similar to a Unity to CME connection. Can something like this be done?
I've read these posts with interest as I need to do the same, I have a remote site (remote from the CallManager) which has a Unity server. How do I configure the Unity to be available to the phones on that site in SRST mode? I've scanned the Unity installguide and see no reference to the SCCP prt integration you talk about.
After a little research, I figured out how to make this happen. First, you need to upgrade to an IOS that supports CME 4.0. Either 12.4(9)T or 12.4(4)XC. The configuration and integration is very straightforward.
CME 4.0 now has a new feature that allows it to run in an SRST-type configuration. Instead of having the SRST config, you configure CME in SRST-mode. You get all of the benefits of CME with the failover of SRST.
You can also integrate Unity with CME using standard SCCP skinny ports instead of a SIP integration. On the Unity side, all you do is add the CME router as another CallManager in the current integration. On the CME side, you configure ephone-dns and ephones that do the same thing as the voicemail ports in CallManager. It works out great.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
