Web browser communication made easy

Real-time communications over the web enriches the experience of customer-facing services and opens up a wide range of new and innovative use cases related to connected devices. For example, doorbells, elevators, surveillance cameras, drones and similar can connect to users over a web-browser.

WebRTC gateway as a function helps you to incorporate web based real-time communications, such as voice and video, into your solution.

WebRTC Gateway from iotcomms.io

WebRTC offers real-time voice and video communications from any device that supports a standard web browser – computers, tablets and phones. Our WebRTC gateway bridges the web and traditional telecom worlds and enables WebRTC functionality from legacy communications infrastructure as well as peer-to-peer WebRTC.

With our function we allow devices, applications and platforms that support the SIP protocol to communicate via webpages or apps. The gateway can be utilized to modernize existing solutions or to speed up the development of new and innovative products and services.

Serverless gateway function

The iotcomms.io platform is built in a modern way utilizing the power of public cloud infrastructure. Our serverless WebRTC gateway function provides you with WebRTC without the need of any local software, hardware or servers. We take care of it all from our cloud platform.

Enables WebRTC from legacy communication infrastructure
as well as peer-to-peer WebRTC

Cloud-based solution that
automatically scales
to meet your capacity needs

No need to worry about
software, hardware, licenses, server
management or availability



Direct your modern WebRTC communications application towards the WebRTC gateway function and we do the bridging back to the legacy SIP device, application or platform.


Our gateway takes care of the rest of complexity seamlessly! It automatically scales to meet your capacity needs and takes care about availability and server management.


The WebRTC application will look like an ordinary SIP endpoint. Our function will proxy SIP Register and Invite Requests and bridge the differences required by the WebRTC enabled browsers.

Example scenarios

Below are three different scenarios to exemplify how the WebRTC gateway from iotcomms.io can be implemented in existing or new solutions.

Connect WebRTC supported devices to your legacy application or platform
Enable voice and video communication between WebRTC supported devices
Enable voice and video communication from IOT devices to WebRTC supported devices

Painless integration

The WebRTC gateway as a function hooks in with existing backend communications applications and ordinary phone systems and trunk services. It enables easy integration using SIP over WebSockets – all that need to be done is to add a route header pointing back to the legacy system. The gateway can also connect WebRTC to WebRTC supported devices.
