What’s The Difference Between WebRTC and VoIP?

Reading Time: 4 minutes

If you’re scratching your head wondering about the technical difference between WebRTC and VoIP, you’ve come to the right place. This is one of our most frequently-asked questions.

First, let’s define WebRTC and VOIP

Voice over Internet Protocol (VoIP) is the process of transmitting bundled voice data over an IP network. VoIP was created to help businesses bypass the publicly switched telephone network (PSTN) when sending and receiving voice calls. VoIP, it should be noted, now falls under the umbrella of “communications over Internet protocol”(CoIP). This can include voice, video, text and other types of data.

Web Real-Time Communication (WebRTC) is an open source standard that enables browsers and mobile applications to transmit data in real time using simple application programming interfaces (APIs) and communications protocols.

Here’s the Difference 

The big difference between the two technologies exists in their underlying infrastructure. WebRTC takes place almost entirely within the browser, except for when the browser has to request resources from backend servers to establish a peer to peer connection or work around a firewall or network address translator (NAT).

VoIP, on the other hand, takes place over the enterprise network. It requires a connection like WiFi, 3G, LTE or broadband to operate. And it also requires a healthy and optimised system of routers, switches, servers and cables. 

So, how do VoIP and WebRTC relate to one another?

Think of WebRTC as a derivative of VoIP. A business may use WebRTC for embedded real-time communication in its website or mobile applications. This is commonly used for customer support purposes. WebRTC and VoIP also share the same transport standards. It’s possible to use WebRTC with a VoIP endpoint. However, you would first need to convert the signalling protocol into a language the VoIP endpoint can understand. To do this, you would need to put a gateway between the media and signalling path.

Keep in mind that VoIP is just one of the many different things you can do with WebRTC. So, while businesses primarily use VoIP for two-way or multi-party conferencing, they use WebRTC for:

  • Add video to endpoints (like ATMs and retail kiosks)
  • Collaborate in real-time
  • Build contextual applications
  • Share screens
  • Share data

Another similarity is how the development and management of both technologies can be outsourced to a third party service provider. You can build your own platforms. But why on earth would you do that, when you can purchase a high quality, fully-managed platform?
