The 3CX Phone System for Windows is an IP phone system that replaces proprietary PBXs (public branch exchange), and supports standard SIP (session-initiated protocol) soft/hard phones, VOIP (voice over IP) services and traditional PSTN (public switched telephone network) phone lines. The 3CX Phone System is far less expensive than a traditional PBX and can reduce call costs substantially when 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 easily work remotely.
The 3CX Phone System for Windows has been developed specifically for Microsoft Windows and is based on the SIP standard, so its easier to manage and allows users to employ any SIP phone. The 3CX Phone System offers numerous benefits including:
- Easier to install and manage the phone system via a web-based configuration interface,
- Less expensive to purchase and expand than a proprietary hardware-based PBX; in fact, users can purchase extensions and add-ons to the 3CX phone system from third parties because the system is fully SIP-compliant and works with G.711, G.729, GSM (Global System for Mobile Communications), and Speex (a patent-free audio compression format designed for speech) codecs,
- More productive due to offering presence, desktop-based call control and extension management,
- Eliminates requirements for separate phone wiring; phones utilize computer networks,
- Delivery mobility allows employees to work from home by simply using a remote extension,
- Users can choose between popular IP hardware phones or softphones; no vendor lock-in as with conventional PBXs,
- Receive and make calls via the standard PSTN using VOIP gateways or cards
- Monthly savings on calling costs due to use of SIP trunks, VoIP providers or the Skype gateway.
The 3CX Phone System supports call switching, routing, and queuing. The 3CX Phone System For Windows Enterprise Edition includes the ability to customize the features, so it will meet requirement for both large and small enterprises. Each edition includes system features including caller ID, conferencing, and hunt and ring groups, a Web-based management console and integrated Web server, an integrated fax server, and integration with leading third-party applications.
3CX provides two application programming interfaces (APIs) to customize the system. First, it provides a call-control API that allows applications to check call status and wrest control of calls. Then there’s a TAPI (telephone application programming interface) that works with any CRM (customer resource mangement) application, starting with Microsoft Outlook, and allows the system to respond to inbound calls by displaying the caller's number and the time the call came in.
The 3CX server integrates a fax server that works within a unified communications system and allows users to receive faxes as PDFs (portable document format). Users may also send faxes from their existing fax machines (via an ATA [analog terminal adapter]) or may use any third-party T.38-compatible FoIP servers.
