Omnistack

A different approach to voice AI

Omnistack is how we build and run voice systems across multiple voice stacks and technologies. It lets us choose the right platform for each agent, and lets you scale specialised agents across the business without the operational burden of managing them.

Built on VAPI, Retell AI, AWS, OpenAI, Anthropic, Deepgram, ElevenLabs, Twilio, Google Cloud, Assembly AI, Groq, PlayHT, Azure, Vonage, Whisper, Fireworks.

How we work

Great customer experiences don’t happen by accident.

They are the result of well-designed systems that guide conversations naturally toward the right outcome. We design, operate, and refine voice systems built for reliability, scale, and continuous improvement.

01

Design comes first

Before anything gets built we decide how a call should move: what the agent asks, when it hands off, and what counts as a finished conversation.
02

Then it gets built to last

Your agents run on infrastructure we operate, so the ten-thousandth call is handled the same way the first one was.
03

Someone has to keep it running

We watch quality, uptime and every integration daily, and correct drift long before it reaches a customer.
04

And keep making it better

Real calls tell us what to sharpen. We listen back, adjust the logic, and the system gets more accurate every month.

Fully managed

Everything underneath your call agents is ours to run.

You get a working phone system. We keep the platforms, integrations, monitoring and improvements behind it running, so nobody on your side ends up owning AI operations by accident.

01

Platform operations

The voice platforms, telephony and APIs behind your agents are ours to run, patch and keep online.

02

Quality monitoring

We track answer rates, conversation quality and provider health, and get paged before you would notice.

03

Systems integration

Agents write straight into the calendar, CRM, dispatch board or ticket queue your team already lives in.

04

Continuous tuning

Every week of live calls gives us something to sharpen, so accuracy climbs instead of drifting.

05

Capacity on demand

A hundred callers at once is the same as one. Concurrency expands with demand and costs nothing idle.

06

Compliance posture

Deployed on infrastructure aligned to SOC 2, HIPAA and PCI controls, scoped to whatever your sector demands.

Who we work with

We have built voice systems for more than 150 businesses across 20-plus industries. Most of them are places where a phone ringing out is money walking away.

FAQ

Common questions

How quickly can we go live?
Most businesses are live within a week, sometimes sooner. We handle everything from call routing to conversation design during onboarding.
Do callers know it is an AI?
Our voice agents are trained to sound natural, warm, and professional, and they disclose it honestly when asked. Most callers simply notice that the phone was answered right away.
Do we have to change our phone number?
No. We integrate with your existing phone system through simple call forwarding. Your number stays the same.
What is included?
All engagements include 24/7 availability, appointment booking, lead capture, SMS and email notifications, and CRM integration. We also manage the build, hosting, and maintenance. No hidden fees.
What happens when a caller needs a person?
You decide what gets escalated. The agent transfers the call live and passes the full conversation context, so the caller does not repeat themselves.
How is this different from an IVR?
An IVR makes callers press numbers to navigate a menu. Our agents hold a real conversation, understand what the caller wants, and take action in your systems.
What does it cost?
Pricing depends on call volume, the number of agents, and integration complexity. We size it on a short call. There is no payment until after onboarding.
What systems do you integrate with?
Calendars, CRMs, helpdesks, practice management, dispatch, contact centre platforms, and billing systems. If it has an API, it is usually in scope.
