We have a small business with one central office (with 5 separate telephone lines, each has a different number) and four smaller offices at distant locations, each office has two separate telephone lines, that are not adsl, they are common analog lines. we want to create a small network to exchange files with each other, using the telephone lines (RJ11),
The idea is to setup a linux server on the central office, with four analog modems connected to the motherboard, each connected to a line with a distant office,
We cannot afford a adsl/isdn connection for all offices, so we will use the existing analog lines.
Any help you can provide in details about the hardware needed and the required software will be valuable.
Software/Hardware used: ubuntu server 11.10, 5 H/Y running ubuntu 10.04.
