Telephony · your own PBX

An AI receptionist on the PBX you already run.

Your numbers, your carrier and your extensions stay as they are. The PBX sends a call to SIPmind, the AI answers it, and when a person is needed it hands the call back to your PBX — to an extension, a queue or a mobile.

How a call goes

  1. The call reaches your PBX as always

    Your carrier's incoming calls go to the [sipmind-inbound] context. It streams the call's audio to SIPmind over AudioSocket — a TCP stream to sipmind.net:9092.

  2. The AI answers

    Prices, hours, addresses, booking — from your business description and knowledge base. It sees this customer's earlier conversations on any channel: yesterday's call, last night's WhatsApp.

  3. When a person is needed, the call goes back to your PBX

    To an extension such as 602, a queue such as q-sales, or a colleague's mobile — through a PBX management (AMI) user the install bundle creates. From the hand-over on, no minutes are counted.

  4. After the call

    The dashboard has the recording, the transcript, a short summary (what the caller wanted, what was decided, what to do next) and the customer's card in the CRM.

Where the audio goes, and what stays with you

The audio goes to our server in Germany. The same setup runs in production from Europe, Russia and Central Asia. For large volumes, a server in your region.
No AI keys on your server. Only Asterisk runs there — which some data-residency rules require.
Your staff call customers from the browser and the iPhone app, through your own PBX and your own number.
Status on the page. After installing, the page checks every few seconds and turns green within a minute of your first test call.

Questions before you connect

Do I have to change my carrier or my numbers?
No. Your numbers, your carrier trunk, your extensions and queues stay as they are. The PBX only sends a call to SIPmind and takes it back when a person is needed.
Which PBXs work?
Asterisk, by yourself with the install bundle from the dashboard (we run versions 18, 20 and 22 in production). FreePBX runs on Asterisk. 3CX, Cisco and other SIP PBXs are connected by us, as the Connect your existing PBX service, from $800. With no PBX at all, a SIP trunk from any carrier works.
What happens when the AI cannot answer?
It hands the call back to your PBX: to an extension, a queue or a colleague's mobile. Outside your hours it takes the caller's details and creates a callback task.
What does it cost?
Calls start on Office + Calls: $249 a month with 1,000 minutes of AI conversation. Minutes count only while the AI is on the line; a call handed to your staff stops the meter. Connecting it yourself costs nothing.
Where does the call audio go?
Your Asterisk streams the audio to our server in Germany (sipmind.net:9092). The same setup runs in production from Europe, Russia and Central Asia. For large volumes a server in your region can be arranged.
