[cisco-voip] Cisco Unity Express

[Mike King]

We're currently running Cisco Unity Connection.

For political reasons, we have one site that want's it's own
voicemail.  The site is using a 2921 router with SRST (built in
onboard PVDM).  Besides licenses, what else is needed to add a CUE
card to the router?  I have a quote from a vendor, but it only has
ISM-SRE-300 on it.  I figured they're would be more hardware. (PVDM,
modules, and stuff)  Am I missing anything, or is that all you need
now?
