AI phone — how it works

Updated May 22, 2026

Yaplet's AI phone lets you buy real phone numbers that an AI voice agent answers automatically — in 17 languages, with 30 voices, around the clock. Every call ends up as a transcript in your inbox alongside your chats and emails, so nothing falls through the cracks.

How a call works

When someone dials your Yaplet number, here is what happens in order:

  1. Telnyx connects the call. Yaplet provisions all phone numbers through Telnyx, a carrier-grade telephony platform. Telnyx bridges the inbound call to the Yaplet realtime server.
  2. The voice agent answers. Within roughly 400 milliseconds, the agent plays its pre-generated greeting in your chosen voice and language.
  3. Gemini Live drives the conversation. The agent listens, understands speech in the caller's language, looks up answers from your knowledge base, and speaks back — all in real time.
  4. The call ends up in your inbox. Once the caller hangs up (or the agent ends the call after inactivity), a full transcript and optional recording appear as a conversation thread in your Yaplet inbox.

What powers the voice agent

A voice agent does not have its own knowledge base. It borrows the knowledge, persona, and tools from a Vex AI chatbot you have already configured. That means the same articles, FAQ snippets, and custom tools that power your chat bot also power your phone agent — you update one place and both channels improve.
