How VoIP Phones Work

In the past, phones were wired to an on-premise PBX (Private Branch Exchange). This bulky machine would handle all routing and ensure each call reached its proper destination. VoIP phone features far exceed those available on old PBX systems. Since VoIP phones process telephone calls via the Internet, or the cloud, the technology employs existing computer network cabling or WIFI to access telephone networks. No additional copper wiring is needed to use your VoIP business phone service. Your phone number can stay the same as before, so there is no expense in changing it.

How VoIP Phones Work

Because of this, making a VoIP phone call is simple. Just pick up the handset and dial a number. The technology is designed to make it simple, not more complicated.

This same idea applies to receiving a VoIP phone call. It’s the same as any other

So whichever telephone device your company chooses, you can connect it to the VoIP phone system simply and easily. Just plug the phones in and have your tech team configure the system in a way that best suits your particular needs. If you use a VoIP phone system like nextrings, we will happily help you configure everything for free.

Phone Setup

Instead of the 6-pin RJ-11 phone connectors VoIP phones plug into 8-pin RJ-45 jacks. These RJ numbers are not droid names, but are actually the connectors your computer uses to connect to the internet.

Both the RJ-11 and RJ-45 look very similar. To the average person these connectors would simply be called ‘phone jacks’ or ‘ethernet cables’. But in reality they serve two different purposes.

The RJ-11 is designed to connect analog phones, while the RJ-45 is designed to connect networks. To learn more about the difference between analog and VoIP read our blog post VoIP vs PSTN.

Most VoIP phones need only a network connection or router. Some newer models might not need cables at all and can connect to your network simply through WiFi.
