Bridge voice & video communication between WebRTC and SIP

Use our WebRTC Gateway as a Service for WebRTC to SIP or SIP to WebRTC communication.

Bridge voice & video communication between WebRTC and SIP with iotcomms.io WebRTC Gateway as a Service


What is WebRTC Gateway as a Service?

Simplify communication between browser-based applications and SIP devices with iotcomms.io WebRTC Gateway as a Service

The iotcomms.io serverless WebRTC Gateway as a Service provides the functionality required to enable voice & video communication between WebRTC and SIP devices.

With our gateway, WebRTC clients can be integrated to a PBX or contact center that does not natively support WebRTC. The WebRTC gateway ensures that the communication between the application in the web browser and the PBX/contact center is securely established using public or private SIP trunks.

The WebRTC-enabled device is, just like any other SIP device, registered and configured using the iotcomms.io SIP Server functionality.


How does WebRTC Gateway as a Service work?

The WebRTC gateway works as an interworking function between a mix of SIP and WebRTC devices, which significantly simplifies the communication between browser-based applications to SIP devices. Calling between devices with different protocols have never been easier!

Voice calls between WebRTC clients and external numbers are set up using public SIP trunks. Voice or video calls to an external application such as a PBX or contact center are set up using a private SIP trunk.

Connect to external applications or make external voice calls with private or public SIP trunks

Create and manage user accounts using standard RESTful API calls or accessing the customer web portal. Upon authentication and registration of the accounts, sessions can be set-up end-to-end. Our SIP server functionality will take care of your connectivity in a reliable and secure way. Additional APIs can be used to monitor the status and activity of the WebRTC clients and SIP devices as well as retrieve logs and statistics.

A device monitoring API is provided to listen for SIP registration and dialog state change callback events. The monitoring API can be used to develop applications showing if a device is on-line or in a call.

Connect to external applications (PBX, Contact Center, Customer Support Center etc.) using private SIP trunks, and make external voice calls using public SIP trunks. The service automatically handles NAT traversal.

Traffic is encrypted and authenticated using well-proven encryption technologies. Devices that encrypt signaling using SIP/TLS or SIP/Secure websocket and media encryption using DTLS/SDES-SRTP are extra well protected.

For devices not supporting this an IPSEC VPN connection is used. All data is stored encrypted in our systems.

Benefits of the WebRTC Gateway

Everything runs in the cloud​

No need to setup, run or maintain a SIP infrastructure. Just configure the SIP user accounts using our simple API, configure your devices and start deploying your service.

Add WebRTC to existing system​

Add WebRTC users to your non-WebRTC supported voice system – enable Contact Centers, PBXs or similar to use WebRTC functionality.

Out-of-the-box security​

No need to worry about eavesdropping or manipulation of SIP or media traffic since all traffic is encrypted and authenticated using well-proven encryption technologies. All data is stored encrypted in our systems.

Broad range of codecs and protocols supported

Support for the following codecs: D G.711, OPUS, VP8, H.264. Support for the following protocols: SIP, WebSocket, RTP, SRTP, DTLS, IC.

Avoid codec mismatching ​

Automatic transcoding of codecs between your WebRTC client/SIP device and your trunk provider.

Pay only for what you use

The web portal provides an overview of service usage, and as for all other functionality the data is accessible using APIs. Our microservice-based design enables you to pay only for what you use.
