-multiple sites, (i.e. 3 sites) with a call manager in each site;
-all sites are connected with the public telephone network, so all sites have the same radical numer (i.e. +39065212) and each call manager manage a range of internal number.
- the first call manager manage internal numbers from 0001 to 01000 (by external them are +39065212001 to +3806521200200)
- the second call manager manage numberso from 01001 to 02000;
- the third call manager manage numberso from 02001 to 04000;
I need having one or more call manager in another site (disaster recovery site). If one site is unavailable, the call manager have to replace the call manager installed in the unavailable site. For example if the first site is unavailable the call manager installed in the disaster recovery sites is powered on and have to manage the same internal numbers range of the first site (from 0001 to 01000)
If, in the disaster recovery site I configure 3 call manager eachone like a clone of the 3 call mnager installed in the 3 sites, can it works?
I'm not expert about this, but I think that a cluster provides fault tollerance in case of unavailability of a server.
I need to provide fault tollerance in a network that includes 3 different sites (3 buildings) and a disaster recovery site, so i need to provide service continuity also in case of unavailability of one of the 3 buildings.
Is it possible to solve this problem using a cluster?

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
