VoIP vs SIP explained and what is the difference

VoIP and SIP are two terms widely used in business telecom. Technical terms can be overwhelming when you are looking new telecom equipment for your business. To help you we will explain the meaning of the terms VoIP and SIP and highlight any differences.

What is VoIP

VoIP stands for Voice over Internet Protocol however sometimes also used as Voice over IP. VoIP uses a technique to convert audio into digital channels. The telephone exchange is connected to the company’s local network (LAN) and receives a fixed IP address. Then the VoIP devices are connected to the computer network (LAN) with a PoE (Power over Ethernet) switch. VoIP therefore works wirelessly, so you can call anyone in the world. You can even make calls to traditional network telephones for a small fee.

What is SIP?

SIP stands for Session IP or Session Internet Protocol. SIP enables you to use devices that are connected to the company’s computer network. Unlike VoIP a SIP telephone exchange can be connected in two ways. You can either use the Internet or via a Backbone. You can compare Backbone with the Internet. It is managed by one entity. Most users, in the IP telephony field, use SIP. Simply put, SIP is responsible for initiating, maintaining and terminating calls made over the Internet. The vast majority of VoIP devices use it, including most IP phones. However, there are a few VoIP software clients that do not use SIP. Skype, for example, uses their own system.
