Keep in mind each port in a VG224 is a seperate device. with 73 phones and 35 analogs, this is too much. Which are more critical devices?
I would create a seperate SRST reference for those devices that are not as important.
When devices fail into SRST mode, a virtual dial-peer is configured for them, there is no need to configure seperate dial-peers for each device. The dial-plan should be configured in the 2851. If SRST will be used only for internal calling, given there is not PSTN connectivity, you need only a simple configuration (i.e., ip source-address, max-dn, and max-ephone), with no destination-patterns or session-targets. If the WAN link is down, voip dial-peers are useless.
SRST references are created in callmanager. Which version CCM are you running? You can find this in the system menu under srst. Create the approprite reference for those critical devices and a null reference for those that are less important. In the gateway, you need to configure the dial peers directed to the destination of the redundant link. If you want to continue using dial by extension, configure the dial-peers with a destination-patter of wild cards to match the extensions, and prefix them with the extended pattern, alternatively you can use the alias command to match and prefix numbers (recommended). In this way, when a call is placed using the extension, it matches the dialpeer or alias, the prefix is attached, and the call is sent through the PSTN. Hope this makes sense. If you need more specifics, I'll be happy to provide.
