Asterisk is a free and open source software solution that allows organisations to build VoIP telephone systems. It supports all the features one might expect from a modern telephone solution, including multi-channel and multi-codec support, interactive voice response systems and more.
It’s relatively easy to get started with a simple SIP account and one or more Asterisk (virtual) servers. No need for specialised hardware, no need for expensive online virtual call-center solutions. Asterisk offers everything an organisation needs, whether it’s a corner shop or an international deployment. Find out more about Asterisk.
