[cisco-voip] Multi Site Environment without dedicated voice bandwidth..

[Matthew Loraditch]

reading all of the comments this is what I am thinking of doing.
Getting CUCM-Business Edition for the new site and setting up intercluster trunks for dialing between sites and VPIM for delivering Voice Mail between site. I will have complete survivablity and the the only thing the new site won't have is UM (which I don't think they have ever had nor are they expecting) and if the Internet link goes down all they lose is the ability to dial the home office here in Maryland. The new site is only 80 people/phones so CUCM-BE should be more than sufficient and it cuts down my costs of having to setup a full regular cluster with 2 servers plus another Unity Server.

Has anyone done anything similar or have any thoughts about workability?
Thanks!

the problem here is that its a real gamble. You've seen it work, and
i've seen it degrade to the point where it was completely unusable.
The real problem you have with this sort of thing is the amount of
time/effort it takes to actaully get useful troubleshooting data if
you ever get to that point.
