Hi J,

The 7200 series is still "not" supported

Cisco 1861

Cisco 2801

Cisco 2811

Cisco 2821

Cisco 2851

Cisco 3825

*** Cisco Caalyst 6500 CMM supports Cisco Unified SRST 4.0 with Cisco IOS Release 12.4 and supports Cisco Unified SRST 2.1 with Cisco IOS Release 12.2(13)ZC.

**** SRST 880 is natively supported by CUCM 6.13 and 7.1

Hope this helps!

The 7206VXR does support SRST.  I am currently at version IOS 12.4(18c) and I have Call-Manager-fallback functionality. I am trying to figure out what is the highest IOS that I can go to before the SRST functionality is stripped out.  Cisco has striped out the SRST functionality because they want people to purchased their ISR Branch routers, like a 3825. So I am still trying to find out what the highest IOS version is that still contains SRST functionality.

Thanks for anyones support.

The last mention of the 7200 in SRST platform support is here:

In theory, if it is available on 12.4(18c), then you can run the latest mainline and still get those features.

That being said,I just tested it, and I can get it up on 12.4(22)T.  It at least takes the commands.  I'm going to circle back with our BU because we either need to correct the platform documentation, or remove 'call-manager-fallback' in certain releases:
