Capabilities
A full voice workforce,
not a phone tree.
Inbound, answered instantly
Every call picked up on the first ring, around the clock. BOB greets, understands intent, screens, books and transfers — with live barge-in so callers can interrupt naturally, just like talking to a person.
Outbound at scale
Campaigns, reminders, follow-ups and collections — dialed, spoken and logged autonomously, with webhooks firing after every call.
Knows your business
Agents answer from your knowledge base and live systems — pre-call CRM lookups, calendar free/busy, in-call HTTP tools. No made-up answers.
Any voice, any moment
30+ voices across seven TTS engines — from BOB's native voices to ElevenLabs and xAI clones. Swap per agent, per line or per call.
Acts, not just talks
Mid-conversation tool calling: transfers with AI briefings, voicemail routing, emailed transcripts, bookings — executed while the caller is still speaking.
Carrier-grade under the hood
Not a chatbot bolted onto a phone number. BOB runs on Asterisk-grade telephony — ARI, AudioSocket, native μ-law — fully managed by us. Port your number or buy one, and you're live. You pay for minutes, never for infrastructure.

One second of audio,
four stages of intelligence.
01
The line connects
A call hits your Asterisk or FreePBX box and the dialplan hands it to BOB over ARI — AudioSocket streaming, μ-law native, zero middleware. Outbound works the same way in reverse.
asterisk → stasis(bob-ai)
02
BOB listens
Streaming speech-to-text transcribes the caller in real time — Whisper, Deepgram, Vosk or fully local engines. Barge-in stays live, so the caller can interrupt at any word.

BOB thinks
The LLM reasons over your knowledge base, the pre-call CRM lookup and the live conversation. It decides what to say — and whether to act: transfer, book, escalate.
llm + knowledge base + tools
04
BOB speaks & acts
Streaming TTS overlaps generation with playback, so responses land in under two seconds. Tool calls fire mid-sentence: transfers with AI briefings, emailed transcripts, webhooks.
