Abstracts speech-to-text, text-to-speech and LLM calls so you can swap vendors such as different STT, TTS and language model providers without rewriting your call flow.
Handles inbound and outbound phone calls with number provisioning, call creation, recording retrieval and CDR-style usage endpoints exposed through a documented REST API.
Register webhooks and self-contained actions so an agent can look things up, transfer a caller, or trigger work in your backend mid-conversation.
Supports streaming or turn-based conversation modes, endpointing and emotion tracking, plus browser and meeting-based interfaces beyond pure telephony.
