3CX is an open-standard, software based PBX that works with popular IP Phones, SIP trunks and Gateways. It’s a complete Unified Communications solution, which includes features such as web conferencing, presence, softphones, smartphone clients and more – without the inflated cost and management headaches of an ‘old style’ PBX. As can be seen from the requirements below, this software does not require overly powerful hardware to run. Mostly a desktop computer is strong enough. Please note that the computer hosting the 3CX software should be running 24/7.
