AI phone answering built for healthcare reception, and ready for any business that answers a phone. It books, captures enquiries and routes calls in the systems you already use.
- Dental practice, new private patient. Prime Assist applies the practice’s written rule on deposits and books a new patient exam for Tuesday at 09:15 in Dentally. It texts the caller a secure link for the £25 deposit, which they pay on their own phone during the call. Once the deposit is paid, it confirms the booking by text and saves the transcript.
- GP surgery, a caller who has run out of their insulin. That matches an urgent trigger the surgery agreed in writing, so Prime Assist gives no clinical advice and puts the call straight through to Dr Patel, who joins with the transcript.
- Heating engineer, no hot water. Prime Assist raises a boiler job in HubSpot, books an engineer’s visit for Thursday at 08:00 in Google Calendar, texts the caller the job reference and saves the transcript.

Answer the two questions
Your unanswered calls a week appear here.
The first half hour can be worse than this. The model spreads the hour’s calls at random; if yours bunch as the lines open at 8am, more callers wait, and for longer.
With Prime Assist
10 in 10 answered
Every call answered at once, at any hour.
Routine requests are handled on the call and written into your systems. Anything urgent goes to a named person on your team, with the transcript.
Calculated with the Erlang C formula, the standard way to estimate phone queues. It assumes callers wait rather than hang up, and does not estimate staff time saved or what callers do next.
What they are worth
Answer step 1 first, then these two.
It does not estimate how many of those callers we would win back: that depends on your calls, which is what the demo is for.
Answer all three to see your busiest hour, with and without Prime Assist.
Busiest hour, today
Busiest hour, with Prime Assist
No one waits
Calculated with the Erlang C formula, the standard way to estimate phone queues. It assumes callers wait rather than hang up and that calls arrive at random through the hour: if yours bunch at the start of the hour, more callers wait than this shows. It does not estimate staff time saved, or what callers do when they cannot get through.

How this compares across England
A quarter of calls to GP practices arrive between 8am and 10am on working weekdays (25.0%, our calculation).
Of the calls answered between 8am and 10am, almost a quarter waited more than five minutes (23.5%).
On working weekdays between 8am and 10am, about 1 in 9 calls ended with the caller asking for a call back (11.1%), about twice the rate later in the day (our calculation).

How this works and where the figures come from
It multiplies your figures and nothing else: calls on a typical weekday, times 5 weekdays, times the share that go unanswered. A month is 52 weeks divided by 12, and a year is 52 weeks. Weekends are left out, and so are repeat visits, referrals and reviews. If you put a value on it, the unanswered calls are multiplied by the share you judge were someone wanting to book, and by your value.
For GP practices only, the starting points come from public data, and you can change each one: 27.2 calls for every 1,000 registered patients each working day (September 2025 to August 2026), 10.4% of calls ending while the caller was waiting, including voicemail (August 2026), and 4.4 calls an hour for every 1,000 patients between 8am and 10am on a Monday (August 2026). Source: NHS England Digital, Cloud Based Telephony Data in General Practice, official statistics in development covering 86% of practices in England; the first and last figures are our calculation. Contains information from NHS England, licensed under the current version of the Open Government Licence. Every public figure we use is listed with its date and source on our facts page.
The queue uses the Erlang C formula: from the calls in an hour, the people answering and the minutes a call takes, it gives the share of callers who find every line busy. It assumes callers wait rather than hang up, and that calls arrive at random through the hour, so a rush in the first minutes shows fewer waits than really happen.
