AI Voice Agent for Sinch
AI-answered calls alongside your Sinch voice deployment.
Forward the calls you want AI-answered from your Sinch numbers to PyAI and get a production voice agent without a rebuild. When you want it closer to the metal, the same agent is one OpenAI-compatible API away.
Two ways in. Pick per call type.
Path 1: Forward calls to PyAI
Keep everything exactly where it is. PyAI provisions a number (or takes your SIP trunk), you point your calls at it, and a PyAI agent answers with your greeting, your knowledge, and your tools. Your platform keeps billing you for lines; the AI layer lives at PyAI.
- 1.In the PyAI console, provision a number (Phone) or bring your own SIP trunk.
- 2.Build the agent: pick a voice, write the greeting, connect your knowledge and tools, then call it yourself to test.
- 3.Set the forward on your side using the hint below, aimed at the PyAI number.
- 4.Place one real call. The agent answers; the recap and QA land in PyAI and any tools you connected.
On Sinch: Sinch Customer Portal: set forwarding on the number or divert at your SIP trunk to PyAI.
Path 2: Integrate via API
Keep Sinch for messaging and transport; put the voice intelligence on PyAI.
- One key for the full voice stack: hearing, speaking, and complete Omni voice agents.
- Managed numbers and SIP trunking for the calls you move fully to PyAI.
- AMD for outbound campaigns, per-answered-call billing.
Which path when
Start with forwarding
You want AI answering real calls this week without touching your Sinch setup. One number forward is the whole change.
Add the API when ready
You want the AI leg inside your own call flows, or deeper call-data integration, on OpenAI-compatible endpoints.
Move fully later
When the forward path proves itself, moving whole flows onto PyAI numbers is a graduation, not a rebuild.
FAQ
Do I have to leave Sinch to use PyAI?
No. Most teams start with call forwarding: Sinch keeps the lines and the bill, and PyAI answers the calls you point at it. If and when it makes sense, you can also build directly on PyAI's APIs or import completed calls.
What does the AI voice agent actually do on a call?
It answers in your voice and greeting, holds a real conversation at human pace, uses your knowledge base and tools, and can transfer to a human, collect details, or end the call politely. Afterward you get the recap and, with Trace, a compliance scorecard.
Is call import from Sinch available?
There is no native Sinch importer today, and you do not need one to start: forwarding sends the calls you want AI-answered to PyAI. Importer candidates are prioritized by customer demand, so ask.
What does this cost?
You pay PyAI for the calling and call intelligence you run (per-minute calling, Recap or AMD usage); integrations carry no extra fee. Your existing platform bills you as usual for the lines you keep.
