Every urgent call answered. Every job dispatched.
Cortecx answers your calls out of hours, at peak times and when every line is busy, then texts the job to your on-call drivers in real time. It works alongside your phone system, so there is nothing to rip out.
When nobody answers, customers call the next company.
In urgent trades the caller has a broken shutter, a blocked drain or a site that cannot operate. They are not going to leave a voicemail and wait.

Invoca platform data. SourceThese are published industry figures from UK and US studies, mostly from call-technology vendors. They are not Cortecx customer results. Real case studies will be added here as soon as we have them. Missed calls also cost you beyond the job itself: a caller who cannot reach you remembers it, and so do the people they tell.
What could missed calls be costing you?

- Cortecx managed service: a tailored quote, priced as a small fraction of the revenue it protects.
- Without hiring: no extra headcount, no night shifts, no rota.
This is a simple calculation (calls × unanswered share × conversion × job value), not a prediction or a guarantee. Your own call logs will give a far better number, and we are happy to help you work it out.
From a ringing phone to a driver on the road, in one flow.
Cortecx uses ElevenLabs voice technology and advanced AI models tuned for low latency and natural conversation, so callers talk to something that responds like a person, without the awkward pauses.
Calls are forwarded
Forward your out-of-hours line, or overflow when your team is busy. That is the entire setup on your side.
The AI answers
It picks up straight away in a natural voice and keeps the caller calm while it gathers what your team needs.
The job is captured
Caller details, site address, what has gone wrong and how urgent it is, all recorded in a clear format.
Drivers are alerted
On-call drivers get a text. The first to reply accepts, admin is told, and everyone else is stood down.
Nights, weekends and bank holidays covered, without a night shift.
Emergencies do not keep office hours. Cortecx picks up the moment your office closes, so a shutter stuck open at 11pm or a flooded yard on Sunday gets handled instead of sent to voicemail.
- Answers instantly, every time
- Captures the details your on-call team needs
- Starts dispatch immediately, not at 8am
Ten calls at once is no different to one.
A burst of calls after a storm, a power cut or a morning rush would swamp a small team. Cortecx handles missed and overflow calls at the same time, so nobody hears an engaged tone or waits in a queue.
- Many callers handled simultaneously
- No hold music, no ringing out
- Your team stays free to do the work
EXAMPLE ONLY, NOT REAL CALLS
A clear text, one reply to accept, and everyone is in the loop.
When a call comes in, our system logic texts the job to your on-call drivers in a short, structured format that reads at a glance on the road, with a direct link to navigate to site.
The first driver to text back accepts the job instantly. Admin gets a confirmation, and every other on-call driver is told the job has been taken.
- Plain, scannable message format
- One tap to navigate to site
- Reply to accept, confirmed to admin immediately
- Other drivers notified automatically
- SITE
- Unit 4, Example Trading Estate
- ISSUE
- Foul water backing up, site closed
- CALLER
- S. Patel, site manager

EXAMPLE MESSAGE, FICTIONAL DETAILS
Insurance for the moments your team cannot pick up.
Cortecx is completely separate from your main line and your CRM. It works through call forwarding, so there is nothing to integrate, migrate or break. Calls you already answer carry on exactly as they do now.
Think of it as cover for out-of-hours and peak periods: a safety net that improves your customer experience and makes your business more resilient, while protecting the revenue that leaks away when you are unavailable.
- No changes to your main line or CRM
- Switch it off by removing the forward
- Better first impression for every caller
Separate from your CRM and main line. Connected only by call forwarding.
A managed service, quoted to your call volume.
We set up, run and monitor Cortecx for you, tuned to your trade, your on-call rota and your call patterns. There is nothing to build or maintain on your side.
Pricing is kept to a small fraction of the revenue it protects. Tell us your rough call volume and we will show you the comparison in plain numbers.

Do I have to change my phone system or CRM?
No. Cortecx is separate from both. You forward your out-of-hours or overflow calls to us, and that is all. If you ever want to stop, remove the forward.
Will callers know they are speaking to an AI?
The voice is built on ElevenLabs technology and tuned for low latency and natural conversation, so it sounds fluid rather than robotic. We recommend being open with callers, and we can set the greeting to suit how you want to handle that.
How do drivers accept a job?
They get a short text with the site, the issue, the caller and a navigation link. They reply to accept. The first reply wins, admin is notified, and the other on-call drivers are told the job is taken.
What happens if the call needs a human?
Call handling is set up around your business, including what counts as urgent. Tell us how you want unusual calls treated during the demo and we will build that in.
