The problem
Is your contact center
drowning in calls?
Call volumes climb, wait times stretch, and the only lever left is hiring. It's expensive, slow, and it burns out your best agents.
Overwhelmed agents
High call volumes drive burnout, attrition and endless retraining cycles.
Frustrated customers
Long holds and repeat questions erode loyalty with every single call.
Rising costs
Headcount becomes the only lever — and it doesn't scale with demand.
Measured in production
Numbers your customers actually feel.

How it works
AI that works like your best agent — instantly.
Four steps between the ring and a resolved request.
Instant call routing
Your AI greets callers in under a second. No hold, no queue, no frustration.
Smart intent detection
Natural language understanding covers 100+ needs — billing, support, returns and more.
Automated resolution
Handles 60–80% of routine calls end to end: refunds, hours, order tracking, appointments.
Seamless human handoff
Escalates complex issues to an agent with the full transcript and context attached.
Build your own
Your agent, in four steps.
No scripts, no developers. Tell it about your business and it's ready to take calls in minutes.
Add your website
Optional — drop in your URL and the agent pulls company details, services and FAQs from it.
Describe your agent
Write in plain language who it is and what it handles: billing, bookings, returns, sales — up to 300 characters.
Pick a language
Choose the language your callers speak. The agent greets, listens and answers in it natively.
Generate & go live
Hit Generate agent, sign in, and test it on a real call. Fine-tune the flow anytime — no release needed.

Outbound campaigns
Let your agent make the calls,
on your schedule.
Your agent calls first
Reminders, follow-ups, surveys and re-engagement. The same agent that answers your inbound calls reaches out to your customers.
Scheduled, not scattered
Choose the days and the hours to call. Your agent reaches customers at a good time, and if someone does not pick up, it tries again another day.
Bring your contacts
Upload the customers you want to reach, like people who may be interested in a new offer or are due a reminder. Your agent calls each one for you, and nobody on your team dials a number.

Four hops from your PBX to your API.
No rip-and-replace. Your PBX keeps doing its job — we sit next to it over SIP and reach your systems through a flow you can see and edit.
01 · TELEPHONY
Your PBX → SIP Connector
Avaya — or whatever phone system you run — trunks into our SIP connector over standard SIP. Nothing on your side gets replaced.
02 · AUDIO
AudioSocket — live, one-to-one
The connector streams raw call audio in both directions over a direct, one-to-one link — the reason the agent answers in under a second instead of after a beep.
03 · LOGIC
The flow you designed
Audio hits the conversation flow built in the OpenBrain app. Prompts, branches, guardrails and escalation rules live there — editable without a release.
04 · ACTIONS
Your API, via MCP
The flow calls your systems through MCP tools and REST — checking a balance, moving an appointment, opening a ticket while the caller is still on the line.
THE JOURNEY
Connect your PBX through our SIP connector in a few minutes — and start your agent now.

Questions, answered.
The things technical teams ask us most, before a pilot.
No. Your Avaya or existing phone central trunks into our Asterisk over standard SIP. Your numbers, routing and agent desktops stay exactly as they are — the AI simply becomes one more destination calls can reach.
Through our custom SIP connector, which streams the live audio to and from the agent over AudioSocket. That direct audio path is what keeps the response under a second, with no menus or beeps in between.
Yes — the conversation logic is a flow you design in the OpenBrain app. Prompts, branches, guardrails and escalation rules are edited there and take effect without a software release.
The flow calls your APIs through MCP tools and REST endpoints, so it can check a balance, reschedule an appointment or open a ticket while the caller is still on the line.
Yes. The supervision interface lists every conversation in progress, and a supervisor can stop the AI mid-call and redirect the caller to an Avaya phone, or place an outbound call to their own Avaya extension directly from the interface.
Every call is logged with its full transcript and the path it took through the flow. Supervisors leave comments on specific turns, and those notes become the change list for the next iteration of the flow — the agent gets better from real traffic, not guesswork.
English, Macedonian, Serbian and Croatian are live today, and we can train models for any additional language you need. A single agent can switch language mid-call based on the caller.
EU cloud by default, with on-premise deployment available. Recordings and transcripts support redaction of sensitive fields and full audit logging under GDPR.
Typically three to six weeks: one week of discovery and intent mapping, a shadow-mode pilot on real traffic, then a gradual switch of call volume to the agent.
