3CX is an IP Phone System that completely replaces your proprietary PBX, supports standard SIP soft/hard phones, VOIP services and traditional PSTN phone lines. 3CX is unique as it can run on the Windows operating system, which most people are already accustomed too, so there is no requirement to know Linux like some other VoIP Phone Systems.
3CX Phone System is far less expensive than a traditional PBX and can reduce call costs substantially by using a VOIP service provider. Its web-based administration makes phone system management easy. 3CX Phone System eliminates the phone wiring network and allows users to hot desk simply by taking their phone.
3CX boasts many different editions, but each share the same features and differ in the amount of concurrent phone calls the phone system can handle. If you are looking for a very easy to use, powerful and cost effective phone system, 3CX is an excellent choice.
