3CX PBX System
What is 3CX PBX system
3CX is a software based private branch exchange (PBX) based on the SIP (Session Initiation Protocol) standard. It enables extensions to make calls via the public switched telephone network (PSTN) or via Voice over Internet Protocol (VoIP) services.
This is a complete Unified Communications solution, including web conferencing, presence, softphones, smartphone clients and more – without the cost and management headaches of an ‘old style’ phone system or the limitations of a shared cloud PBX
