Firstly, your post would be better placed in the TelePresence section of the Forums where these things are more actively discussed than here in the Conferencing forums which deal more with Cisco WebEX and MeetingPlace. I suggest you move your thread.
A Cisco TelePresence Server allows multiple endpoints to participate in a single conference. This isn't quite what you're looking for, but may be a part of your total solution.
Your best approach is going to be to investigate what they actually have infrastucuture wise on each of the sites and to see if they are able to dial off-site from what they have. If they can, they may be able to dial each other already.
In the Cisco world, look for VCS-Expressways and/or ISDN Gateways and their equivalent (Polycom Gateway products) in the other site.
Once you've got some more information about what you have at each site, it'll be easier to assist you come up with a solution to link the two.
