This is the perfect place for a gatekeeper.  Place a gateway at each location with appropriate trunks (PRI, BRI, etc.) to each PBX.  Dial peers on these gateways to route calls to a centralized gatekeeper, and voila.  I'm drastically oversimplifying, but the gatekeeper will give you a single location for centralized call routing amongst the gateways.

Hi all, I need some help (obviously) :)))
I have a customer with a bunch of TDM PBXs on different locations and
now wants to interconnect all of them into one big voice cloud :)
My question is, what is the best way to do this? I was thinking of VG
on each location that would use 2xBRI ports to connect with the TDM
PBX and a eth0 interface would be connected to a WAN link. I'm not
sure how can I do this exactly :( they are going to use leased lines
to the central location...So i guess that every VG would have to have
a configuration just as a normal VG with dial peer directing to the
central location, where the central VG would have the dial peers for
every location and would route the calls based on dial peers. Do I
need some call manager express in place? If I can manage that all the
locations can connect directly I guess that I can make a dial peers on
each router that would route the calls to the appropriate VG that has
that numbering plan.
Any ideas or maybe even some on site experience???

Thanks
