“We cannot afford a adsl/isdn connection for all offices, so we will use the existing analog lines.” ….. why could not u capable to make connection that is not clear here, is there driver probs / Linux did not recognize the modem / what kind of conn u r using like ppoe or others….. r u using any gui feature like kppp etc that could not reach the goal what is it. r u using slip / ppp conn for that purpose. I worked on the same environment and now my SuSE server is connected via modem with remote comp(XP) where files and our biometric data is downloaded thru modem and phone line. Although I used SuSE (u r using Ubuntu) linux but I think all linux has core architecture and command line almost same. It might be that, my opinion is not on the right way, though ur Q is interesting and hope u will solve ur probs definitely.

we have not established the network yet, i am trying to figure out, what modems to use, which gui, what applications, and how to connect them.
it seems that you have succeded in creating such a network, please please provide some information on how to create the network
