3CX: software-based IP PBX Phone System.
3CX Phone System for Windows is a software-based IP PBX that replaces traditional proprietary hardware PBX / PABX. 3CX’s IP PBX has been developed specifically for Microsoft Windows and is based on the SIP standard – making it easier to manage and allowing you to use any SIP phone (software or hardware). A software-based IP PBX / PABX offers numerous benefits:

• No need for separate phone wiring – phones use computer network
• Easier to install & manage via web-based configuration interface
• A software-based IP PBX is far less expensive than a hardware-based PBX / PABX
• Employees can move offices without requiring any changes in the wiring or IP PBX configuration
• Choose from the many SIP based hardware phones instead of getting locked in with one vendor
• Receive & Make calls via the standard PSTN using VOIP Gateways
• Save on call costs with 'out of the box' configurations for popular SIP / VOIP providers.

VOIP Client

The 3CX VOIP Client is a small Windows application that allows you to make and receive calls via your desktop phone or using a headset connected directly to your computer. You can see the extension numbers of other users and whether they are available to take calls. Important is that you can use the 3CX VOIP client without having to use the head-set: you can continue to use your desk-based phone if you prefer.The 3CX VOIP client ships with all editions of 3CX Phone System, including the Free edition. However, in the Small Business, Pro and Enterprise editions, the 3CX VOIP client allows you to see the presence of other users on the phone system. In the FREE edition, other extensions appear greyed out.

Overview


A complete 3CX Phone System for Windows consists of the server software, soft phones or SIP hardware phones, and a VOIP Gateway to connect your existing phone lines. A VOIP provider can be used to leverage low cost calls across your user network. The system can use the existing computer wiring (and share the network point with the computer) and can be installed on an existing, non-dedicated Windows server (no need for Linux!) or run as a virtual machine. Say goodbye to expensive, proprietary, phone system expansion modules and costly phone bills!

Web based console: Configure and Monitor from anywhere



The web-based interface makes 3CX Phone System configuration and management a breeze. No need to learn an obscure, archaic phone system interface or pay for the phone system supplier to make configuration changes. You can monitor phone system status, including which extensions and PSTN lines are busy, and more, from a web browser.

Keep using your existing phone lines with a VOIP Gateway


With 3CX Phone System you can continue to make and receive calls on your existing phone lines using a VoIP Gateway. 3CX includes out of the box configurations for leading VoIP Gateways and Sangoma cards. Analog and BRI gateways start at as little as 300 €!

Use VOIP providers to lower your phone bills



Save on costs by making international / long distance calls via a VOIP provider. Create network-wide least-cost rules that route calls based on destination. 3CX provides tested 'out of the box' configurations for many popular VOIP providers.

Managing extensions on 3CX Phone System



Scale to more extensions simply by adding SIP phones and configure user preferences with a few mouse clicks. Phones can be moved around the office without the need for any configuration or patching – saving valuable administrator time!

Managing lines and DID numbers with 3CX Phone System



With 3CX it is easy to manage your phone lines and DID numbers. For example, to route a particular line or DID number to a different extension, click on the line in the management console and make the relevant changes.

3CX Assistant



3CX Assistant offers extension users an easy way to transfer, divert, launch or park calls - via “drag and drop” rather then via a cryptic phone interface. In addition 3CX Assistant offers unified communications features such as extension status (presence) of other users and Call Queue information. 3CX Assistant works in tandem with any IP phone (including 3CX VoIP phone) or even analog phones.

With 3CX users can easily see the presence of other users and avoid unnecessarily making or transferring calls. Presence is displayed in any standards-based SIP client, including 3CX VOIP Client and SIP hardware phones (BLF). Deliver mobility by allowing users to make and receive calls from anywhere - even from home. Unify voice mail and faxes with email by having them all delivered to the users’ inbox.

My-phone user portal: Self-service and save administrator’s time!



With the My-phone user portal feature in 3CX Phone System, users can easily configure their extension preferences. Forward calls to voice mail or to another telephone extension or external number - even a mobile phone number - when the phone is not answered or busy. The My-phone portal is accessed via a browser and is so simple that you don’t need the IT Manager to do it for you!

Use Outlook/CRM contacts as your phone book



3CX Phone System has full integration with Outlook, Salesforce.com and other CRM systems. You can initiate phone calls directly from Microsoft Outlook or Salesforce.com without having to enter the phone number. The call will be setup automatically and logged. Upon receiving an inbound call, the contact record will automatically be opened based on the Caller ID. Call duration and missed calls are logged as well, saving personnel valuable time.

All network users can send and receive faxes with 3CX


3CX Phone System includes a fax server feature that allows faxes to be received via email as PDF files. Faxes can be sent via a regular fax machine, using a compatible T38 ATA and the T38 feature in your gateway. It is also possible to use inexpensive third party software to send out faxes.


Eliminate branch office phone bills with 3CX bridges


With 3CX, remote/branch offices can be easily connected so that all inter-office calls are set-up as internal calls and therefore FREE. You can also setup bridges with customers or partners that use 3CX or other SIP PBXs and eliminate phone charges. Watch business communication improve!

Provision phones automatically


3CX Phone System can automatically configure popular SIP hardware phones with the appropriate extension settings. Advanced phone features such as a central company phone book, MWI (Message Waiting Indicator), BLF (Busy Lamp Field – to monitor status of other extensions) and Intercom/Paging are automatically configured and updated.

Call conferencing: Host your own conference calls


3CX allows you to easily setup conference calls that include employees from local and remote offices, as well as, external callers. Leverage 3CX bridge infrastructure to make free conference calls. Easy ad hoc guarantees flexibility – no need for complicated, costly and unreliable conference call services.

Enterprise features: Call Queuing, IVR, Intercom/Paging



3CX Phone System includes enterprise level features as standard. Set-up auto attendants / digital receptionists and call forwarding rules based on Caller ID, time and type of call. Queue calls and distribute to agents as they become available. Page groups of users to broadcast a message or call a single user via intercom. 3CX also integrates a complete voice mail system.
