Frequently Asked Questions

What is Voice over IP (VoIP)?

Voice over IP, or VoIP, is short for Voice over Internet Protocol and refers to the transmission of voice traffic over an Internet connection. In traditional telephony, also known as PSTN (Public Switched Telephone Network), users call landlines and mobile numbers over physical telephone lines, cable systems, and networks. However, IP telephony is much more versatile and also provides the ability to transmit voice, data and video to various devices such as smartphones, laptops, tablets and IP phones at a much lower cost.

What is a 3CX Phone System?

A 3CX phone system is a PBX, which stands for Private Branch Exchange. This is a private telephone network used within a company. The users of the PBX telephone system can communicate internally (within their company) and externally (with the outside world) through various communication channels such as Voice over IP, ISDN or analog. With a 3CX, you can also have more phones than physical phone lines (PTSN) and make free calls between users. In addition, it offers features such as call forwarding, voicemail, call recording, interactive voice menus (IVRs), and call queuing.

Time and technology have changed the telephony landscape for consumers in recent years, with the Open Standards based IP 3CX as the standard bearer. Now you can make calls using the Internet Protocol technology. 3CX telephone systems are available as hosted or virtual (cloud) solutions and as on-premise solutions on your own hardware.
