Blind transfer support for SIP phones
Blind transfer is when a person who transfers the call won't talk with the person to whom he transfers it.

We are happy to announce the high quality speech recognition for both audio call records transcription and real-time recognition scenarios.

The new version of Web SDK will help us to accelerate the development process and includes a lot of new features and improvements.

Now developers can use Promise in their VoxEngine scenarios and we also added Net.httpRequestAsync and Net.sendMailAsync functions.

Your mp3 or ogg files played on VoxEngine scenario level with call.startPlayback or using Player will be played on the Web or Mobile SDK side in HD quality (48KHz), or on SIP side if it does support wideband audio codecs (Speex or Opus).

In HD mode audio is being mixed at 48KHz, all audio sources with lower sample rate will be resampled to 48KHz.

We chose 48 KHz as the base sample rate for HD audio recorder, since WebRTC/Opus can offer this quality, audio from endpoints with lower sample rate will be re-sampled.

Full Featured Instant Messaging

If a call is made in non-P2P mode then its media stream goes via our media servers and we can record it if required.

We've started with audio, then we've added video calls and now it's time to let our developers use instant messaging and presence - two very important features of UC stack.

The new version of our mobile SDK uses WebRTC engine for audio/video processing and supports all features available for WebSDK.

Victor Pascual from Quobis invited us to participate in WebRTC meetup that took place on March 4th in Barcelona, we accepted the invitation and I'm really happy that we did.

OpenAI has recently announced GA version of their Realtime API that Voximplant now fully supports

In this digest, we will bring you the latest updates to Voximplant Kit. We have added support for outbound WhatsApp messages, Mobile chats, support for ElevenLabs neural voices, and new automated campaign settings.

Check out the latest useful Voximplant Kit updates — we developed chat analytics, improved call history, added new tools for supervisors, expanded scenario capabilities, and updated the softphone. Below is a brief overview of the essential enhancements.

Voximplant now includes a native Cartesia module for streaming, low-latency text-to-speech (TTS). You can use a single VoxEngine API to synthesize speech in real time, connect it to any call (PSTN, SIP, WebRTC, WhatsApp) and control playback from a Large Language Model (LLM) or other source, all inside VoxEngine.

Connect any Voximplant call to ElevenLabs Conversational AI agents

New integrations for Voice AI have arrived: Google's Gemini 2.0 Flash model, featuring seamless voice-to-voice conversation capabilities and ElevenLabs low-latency streaming speech synthesis are now available for Voximplant developers

The new integration enables instant connection of any Voximplant call to an Ultravox agent, delivering seamless voice-to-voice conversations.

Voximplant now includes a native Deepgram module that connects any Voximplant call to Deepgram’s Voice Agent API for real-time, speech‑to‑speech conversations. You can stream audio from phone numbers, SIP trunks, WhatsApp, or WebRTC into Deepgram’s unified agent environment—combining STT, LLM reasoning, and TTS—and play responses via Voximplant’s serverless runtime with minimal latency.
