VoiceBlender v0.5.0 is out — headlined by WhatsApp calling support and configurable speech detection.
What’s New
WhatsApp Business Calling
This release introduces support for WhatsApp Business calling, allowing the platform to integrate directly with one of the world’s most widely used communication channels. VoiceBlender supports inbound calling (User-initiated) as well as outbound (Business-Initiated) WhatsApp calls.
SIP-TLS and SRTP-DTLS
VoiceBlender now supports SIP over TLS and SRTP with DTLS key exchange, enabling encrypted signalling and media for secure voice communications. This is essential for deployments that require end-to-end encryption and compliance with security policies.
Configurable Speech Detection
Speech detection is now fully configurable, allowing you to tune sensitivity, timeouts, and behaviour to match your specific use case — whether that’s an AI agent conversation, IVR input, or barge-in detection.
Call Direction in Ringing Events
The ringing event now distinguishes between inbound and outbound calls, making it easier for your application to apply different logic depending on call direction without tracking extra state.
Bug Fixes & Improvements
- Fixed AMD and deaf event handling.
- Improved OpenAPI specification generation.
