PABX Telephone System 

Replacing ageing PABX can be an expensive exercise if you want to stay with brand names that were on the foreground many years ago. Technology and the rapid development of the open source Asterisk pabx has changed the world of pabx’s forever.

With technology we have today it is possible to run a complete pabx with countless features on a single pc. VoIP or traditional telephones can be used and there is no need to install expensive telephone cabling since VoIP telephones use the same cable infrastructure as your computers on the data network. It is also possible to have an extension at any location where you have a wireless network or cabled Ethernet network. Doing least cost routing through VoIP providers can make a huge difference on your bottom line.
