3CX Phone System is an open standard Windows-based IP PBX that provides superior features and flexibility at a far lower cost and replaces traditional PBX hardware phones. It supports popular SIP phones, VoIP providers and traditional PSTN lines. 3CX Phone System's web-based management console makes it easy to configure, eliminating the need for expensive maintenance.

3CX Phone System includes a client (available for Windows, iPhone and Android) that makes call control, conferencing and other unified communications features a breeze. Users can manage their extension and their calls with just a few mouse clicks and avoid using a cryptic phone interface. What's more, you can log in to 3CX from any computer or smartphone to see the status and presence of other users from your office and any bridged offices around the world.

3CX Phone System includes an iPhone and Android client that allows you to make and receive office calls on your iPhone or Android smartphone from anywhere. Save on telecommunications costs by making internal office calls free of charge, and keep your mobile number confidential by using the office caller ID. Never miss that all important call by answering calls made to your office extension from anywhere.

3CX Phone System is available in several editions based on the number of simultaneous calls (internal & external) your company makes. Upgrades are activated instantly with a license key - there's no need to reinstall 3CX Phone System. A detailed feature comparison table can be found here.

Unlimited Lines

Callers never get a busy signal, and each phone number can point to as many or as few phones as you want. Our phones are location independent, so someone dialing your main number can make a phone ring at both your office and another location at the same time. Also, everyone in your company can use the same outbound Caller ID, or each person can have their own direct number. Traditional phone lines will eventually be remembered as a thing of the past. Auto Attendants

Auto Attendants

For an initial greeting, missed calls or maybe after hours, an auto-attendant can answer calls for you. In fact, callers can be directed however you wish. They can be provided with transfer options, emergency instructions, or sent to a designated voicemail. Callers will never hit a dead end.

Mobile Office

When a call comes in to your work number, you can have it sent anywhere you like – to your cell, to your home line, or even to a colleague. Not only can you seamlessly take calls on your mobile phone, but just by pressing # you can transfer the call back to someone in your office, or even another number.

Call Recording

24/7 call recording for no additional cost. Full time and system-wide recordings are useful for monitoring service quality, preserving important discussions, and can even be used to protect the company from legal liability. (And if you’d prefer not to record calls, this feature can be disabled.)

Visual Voicemail

Access your voicemail online, on our mobile app, or through your email inbox. You can listen to messages; forward them, delete them, and manage everything in one spot. Voicemail doesn’t have to be aggravating, and with Spectrum, it isn’t.

Web Portal

Listen to voicemails, review recordings and look at call logs, set up call forwarding, and manage your speed dials from our online interface. If making programming changes isn’t your thing. You can call or e-mail our outstanding support staff and we will do any system administration for you, free of charge.

Orionox offers a wide range of software to make your job easier and get more done at work. From CRM business management tools to call center software integrated into your VoIP solution, Orionox has you covered.
