We are happy to announce that video calls that use H.264 video codec can now be recorded. Recorded video calls that use H.264 will be stored as mp4 files (calls with video in VP8 format are stored as webm files). There are few ways to enable H.264 in your video calls: - Use H264first Config param (Web SDK) - Use H264first flag in CallSettings (Web SDK) - Mobile SDKs are being updated to let developers enable H264 in video calls According to the following research from Chris Koehncke using H.264 instead of VP8 can save up to 50% in terms of power consumption https://www.chriskranky.com/webrtc-impacts-on-battery-life/ , in addition to that mp4/avc is widely used and supported by most players in both online and offline worlds. See the example of video recording below (Firefox->Voximplant, no post-processing) https://vimeo.com/215691569 P.S. Feel free to ping us if you have any problems with video call recording
Grok Voice Agent API now available in Voximplant
Voximplant now includes a native Grok module that connects any Voximplant call to xAI’s Grok Voice Agent API for real-time, speech-to-speech conversations. With a single VoxEngine scenario, you can interact via audio with Grok over phone numbers, SIP trunks and infrastructure, WhatsApp Business, or WebRTC into Grok — all without building custom media gateways or WebSocket streaming infrastructure.
