What is VoIP and how can it benefit a business?


Since its launch in 1995, Voice over Internet Protocol (VoIP) has radically changed the way we communicate. This technology allows users to make and receive calls through an IP instead of traditional telephony. Through VoIP, companies obtain the flexibility they need in their multiple work environments.

According to a 2021 report of Global Market Insights, VoIP is estimated to grow at a Gross Revenue of 15% from 2021 to 2027 with a USD 95 Billion value projection. This estimated growth is not surprising, considering all the benefits it offers to businesses, such as cost-efficiency and increasing productivity.

Let’s dive into the types of VoIP and all the benefits businesses see from adopting it.

Types of VoIP

There are two main types of Voice over Internal Protocol: SIP Trunk and Cloud PBX.

SIP Trunk

SIP Trunking is the process of connecting a phone system to traditional networks and other systems. A SIP is essential to enable Microsoft Teams Direct Routing.

Cloud PBX

Cloud PBX is a virtual phone system that provides a secure and reliable business phone system through the internet. So, instead of hosting software on a server the way SIP Trunk does, Cloud PBX hosts all software and data in the cloud.
