I have already created a thread about setting up a telephone 'network' which has resulted in me looking at Asterisk PBX software. I understand what the software does but I get a bit lost/confused when it comes to the hardware requirements, and therefore the likely costs involved.
I want to set up about five phones on a PBX using one incoming NTL (VirginMedia) line. Originally I just wanted them to be able to dial out via cat5 cabling but looking at this software I could get a lot more for my 'money'. Any help/advice appreciated.
