Voximplant now supports VoIP Push Notifications for calls to iOS SDK.

Video calls that go via Voximplant servers (not P2P ones) are billed per megabyte of video traffic.

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.

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.

Voximplant now lets developers build full-cascade voice AI pipelines in VoxEngine without sacrificing turn-taking quality.

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.

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