Voximplant, a communications cloud platform built specifically for mobile and web app developers, today announced the beta release of its Web SDK 4.0. The newly available SDK, currently in beta, allows developers to more easily embed voice and video communication into any web application. This release includes an array of valuable enhancements that improve call quality, unlock new call features for users, and empower developers with new capabilities to customize voice and video communication within their apps.

The Web SDK release arrives as Voximplant’s growth continues. Founded in 2013, the real-time communication technology company has been sustaining 100% year-over-year sales increases. This doubling in the size of Voximplant’s business has driven a rapid expansion of the company’s capacity to facilitate new clients and support an increased call load. Voximplant now sees tens of millions of calls completed through its service every month. By releasing its Web SDK 4.0 beta, Voximplant is refining the service’s quality and introducing new features to further fuel its continued growth well into the future.

Key features of Voximplant’s Web SDK 4.0 include:

  • Support for audio calls in Microsoft Edge. With Microsoft recently updating the browser’s web and audio support, Voximplant is one of the first companies to make its platform compatible with Edge. With Web SDK 4.0, web apps are empowered to handle incoming and outgoing voice calls from within the Edge web browser. Video calls in Edge will be functional as soon as VP9 or h.264 codec support is added to the browser.

  • Video can be enabled during an existing audio call. Now developers can create web apps that offer a Skype-like "enable video" option during active audio calls. Video can be enabled or disabled at any time during the call.

  • Both local and remote audio and video streams can be modified by applying filters. Developers can now modify video and audio streams in realtime. Possible applications of this feature include using video and audio filters to add watermarks, hide or alter faces, mask voices, etc.

  • h.264 video codec can be set as "high priority.” The "h.264" video codec is known for its valuable speed in modern hardware, especially in mobile devices. Developers can now force this codec to provide better video quality with less CPU usage.

Additional enhancements include:

  • Reduced latency of audio and video calls.

  • Improved syncing between audio and video tracks.

  • Calls within the Chrome browser now maintain better performance – even with poor network conditions.

  • Peer-to-peer connections can now be enabled in scenarios using JavaScript in the cloud.

  • Audio and video codec priorities can be manually configured.

  • Full support for WebRTC to offer users the best in voice and video quality.

Voximplant also supports asynchronous initialization. Web SDK 4.0 drops support for Flash, which can still be used with legacy systems via 3.x versions of the SDK. Complete documentation for Voximplant’s Web SDK 4.0 beta can be found at https://voximplant.com/docs/references/websdk4/.

“Voximplant differentiates itself by the ease with which our service can be implemented, and by the thorough support we show our developers,” said Alexey Aylarov, CEO, Voximplant. “With our Web SDK 4.0, we’re continuing along this same path that has guided our success so far. We’ve introduced quality improvements, adapted to the newest browser and codec needs, and made it simpler than ever for developers to add audio and video communication to their web apps.”

“Voximplant has become an essential technology for our business, providing our customers with incoming and outgoing calls that are flawlessly integrated into the web interface of our CRM,” said Sergey Rizhikov, CEO, Bitrix24. “Our developers were able to get Voximplant up and running with ease and have found maintaining it to be simple. We look forward to continuing our partnership with Voximplant and making use of all that its new tools have to offer.”
