Choose your planTwilio carries the call; you still bring the model
Here is how Twilio and Frequency differ.
Twilio ConversationRelay turns a phone call into text for your app and speaks your replies back, with Google, Deepgram, Amazon and ElevenLabs doing the listening and the speaking. You bring the language model and host the WebSocket. We sell the whole call: our own speech recognition, model and voice, on our GPUs in India, priced in rupees with the line inside on pay as you go.
Twilio is the pipe a lot of the world’s calls run through, and ConversationRelay is its AI leg. It listens with Google or Deepgram, speaks with Google, Amazon or ElevenLabs, and sends the caller’s words to a WebSocket you host. Your server answers with text, from whichever language model you pay for. If you already live in TwiML, that is a tidy way to add an agent.
It is also three things to run and three bills to read. The AI leg, the call leg and the model each have their own price, in dollars. And the India guideline is strict about numbers: outbound calls to India can only be made from international (non-Indian) numbers, so the customer sees a foreign number ring.
We sell the whole call. The speech recognition, the model and the voice are ours. The model is the open Gemma 4 26B, on our own GPUs in India, where every call runs. On pay as you go the phone line is in the price, and the agent calls from a +91 number.
