Answering service for physician practices

Medical answering service with an AI agent

At 5 pm the practice closes, and the answering service decides what each patient hears. Asyntai takes those calls on your number with AI. It gives the on-call physician number that your rule names, tells callers with an emergency to dial 911, and turns refill and appointment requests into callback requests with a number the patient confirmed.

Four after-hours jobs a medical answering service must get right

The agent opens each call by telling the caller it is an AI assistant and speaking your greeting. From there, your AI Instructions decide which of these four paths the call takes.

The on-call physician, by rule

Your AI Instructions name the on-call physician number and the kinds of concern that should get it. A patient whose problem cannot wait for office hours hears that number and dials it. When the call schedule changes, change the number in the rule; from the next call on, patients hear the new one.

“It's Sunday, and my daughter's fever has not come down since last night.”

Emergencies sent to 911

A second rule lists what your physicians treat as an emergency on the phone. For those calls the agent tells the caller to hang up and dial 911, in the words your physicians approved, and adds nothing of its own about the symptoms.

“My wife fainted and now she is very confused.”

Refills held for the morning team

An evening refill call becomes a callback request. The agent asks for the patient's name and a number, says the digits back and waits for a yes, then emails the request. The medication and the pharmacy are in the transcript, in the patient's own words.

“My inhaler is nearly empty and the pharmacy says it needs a new prescription.”

Overflow while the desk is full

In the daytime, calls that ring out at the desk can go on to the agent. It answers office questions from your website, and a patient who asks for a person is put through to the line's transfer number during your Escalate to Human hours.

“Are you open on the Friday after Thanksgiving?”
Your call instructions

The instructions you would give an answering service, written once

A medical answering service runs on instructions: who is on call, what counts as an emergency, what to do with a refill. With Asyntai those instructions sit in your AI Instructions, next to your website and the documents you upload.

  • Your practice websiteOffice hours, holiday closures, locations and parking, the new patient page and the physicians you list. Asyntai reads it page by page.
  • Policies as documentsThe after-hours policy, the refill policy, the holiday schedule for the year. Upload a PDF file or paste the text.
  • Routing rules your physicians approveThe on-call number and when to give it, the emergency list with the 911 instruction, and how to answer a pharmacy or a hospital that calls.

The morning after

What waits for your staff when the practice opens

An answering service is judged by the morning. With Asyntai the night's calls are already sorted: the questions are answered, the urgent callers had a number to dial, and the requests sit in the escalation email with numbers that were checked.

  • Requests in the escalation emailRefill and appointment requests arrive as callback requests, each with the patient's name and a confirmed number.
  • The night in writingEvery call is a conversation in your dashboard with the full transcript, including the calls that ended with an answer.
  • Daytime cover with a way back to youDuring your hours, a caller who wants a person goes to the transfer number. No answer in 20 seconds, and the agent takes a callback request.

Setup

Send the after-hours line to the AI answering service

The number the agent picks up lives in your own Twilio account, which bills you for it and for the call minutes. Patients keep dialing the practice number; your phone provider forwards the calls you choose.

  1. Create an Asyntai account with your practice website. Upload the after-hours policy and the holiday schedule. The pages are read in a few minutes.
  2. Write the on-call rule and the emergency rule in your AI Instructions, with your physicians. Then write the greeting on the Voice Agent page and call the agent for free from your browser, as a patient at 9 pm.
  3. Connect Twilio on the Phone Calls page with your Account SID and Auth Token, and import the number that will take the forwarded calls.
  4. Set the transfer number and your hours under Escalation, then ask your phone provider to forward calls after closing, or when nobody answers. Ring the line yourself to hear it.

FAQ

Medical answering service: what practice managers ask

For physician practices and clinics that compare an AI answering service with the one they pay for now.

Can an AI answering service cover a medical practice after hours?

Yes. Forward the practice line to a number in your Twilio account when the office closes. The agent says it is an AI assistant, gives your greeting, answers office questions from your website and documents, and follows your rules for the on-call physician, emergencies and refills.

How does a patient reach the on-call physician at night?

Your AI Instructions hold the on-call number and the cases that should get it. A patient with a concern that cannot wait hears the number and calls it. If your physicians rotate, update the number in the rule on changeover day. A shared on-call phone means the rule can stay as it is.

What does the agent say when a caller describes an emergency?

What your emergency rule says, for example: hang up and call 911 now. Your physicians choose the list of symptoms and the wording. The agent repeats that instruction and gives no opinion of its own about the symptoms.

Do refill requests reach us with enough detail to act on?

Each refill request arrives at your escalation email with the patient's name and a callback number that the agent repeated digit by digit and the patient confirmed. The medication, the dose the patient mentioned and the pharmacy are in the call transcript in your dashboard.

Can patients make an appointment through the answering service?

Appointment requests arrive as callback requests, with the reason for the visit and the times the patient asked for in the transcript. Your schedulers book the slot in your own scheduling system and call the patient back on the confirmed number.

Can we use it for daytime overflow only?

Yes. Your phone provider decides which calls go to the Twilio number: all calls, calls after a set time, calls nobody answers, or calls that meet a busy line. During your Escalate to Human hours, anyone who asks for a person goes through to your transfer number, such as the nurse line.

Can a pharmacy or a hospital reach a person?

During your Escalate to Human hours, yes: the agent says it is putting the caller through and transfers the call. The receiving phone shows the caller's own number. Outside those hours, a rule can give a pharmacy or hospital the on-call number, or the agent takes a callback request.

How do we set the plan price against a per-minute service?

Take the last invoice from your current service and note the minutes or calls on it. Standard costs $139 a month and includes 200 voice minutes; Pro costs $449 and includes 1,500. The number and the minutes on the Twilio side are billed by Twilio. Every answer the agent speaks also uses one AI reply.

What do we need before we switch from our current service?

Asyntai Standard or Pro, plus a Twilio account (not a trial) that holds at least one number able to take voice calls. Before you buy a number, Twilio can ask you to verify the business. Keep the old service running while you test the agent in the browser, and move the forwarding only when the answers are right.

Choosing a medical answering service: AI or a traditional service

A physician practice needs someone on the phone after the doors close. Patients wake up with a fever, run out of a medication on a Saturday, or come home from a procedure with a question that cannot wait until Monday. For years the usual answer has been a traditional medical answering service: operators who pick up in the practice's name, follow a script and pass messages on. An AI answering service does the same job with a voice agent. This page compares the two from the point of view of a practice manager, and shows how Asyntai handles each kind of call.

Start with what an answering service is for: getting each caller to the right next step. That means the on-call physician for a concern that cannot wait, 911 for an emergency, and a request in the morning queue for everything else. With Asyntai, each of those steps is a rule you write in plain English in the AI Instructions. One rule names the on-call physician number and the kinds of concern that get it. Another lists what your physicians treat as an emergency on the phone, and tells the caller to hang up and dial 911. The agent repeats the wording you chose and adds nothing about symptoms.

The on-call rule is where the practice keeps control. If your physicians share one on-call phone, the rule rarely changes. If each physician carries their own number for their week, edit the rule when the rotation turns over, and the next caller hears the new number. The patient dials it themselves, so the physician on call sees the patient's own number on the screen. Instructions take effect on the next call, so a schedule change on Friday afternoon applies to the first call on Friday evening.

Refill and appointment requests are typical night calls for a medical answering service, and they do not need a person at 10 pm. They need to reach the right person at 8 am with the right details. When a patient asks for a refill, Asyntai writes a callback request: it collects the patient's name and the number to ring back, repeats each digit of that number, and waits until the patient says it is right. The request goes to your escalation email. The transcript in the dashboard keeps the rest: which medication, which pharmacy, how many tablets are left. Appointment requests follow the same path, and your schedulers book the visit in the system they already use.

The second job of an answering service is overflow during the day. At a busy internal medicine practice the desk staff check patients in, take payments and field calls from pharmacies and specialists. You can forward the calls nobody picks up, or the calls that meet a busy line, to the Twilio number. The agent answers office questions from your website and documents: hours, the holiday schedule, parking, which entrance leads to the lab. During the hours you set under Escalate to Human, a caller who asks for a person is put through to the transfer number of the line, such as the nurse line. A transfer that rings for 20 seconds with no answer, or hits a busy line, brings the caller back to the agent. It apologizes and writes up a callback request.

When you compare costs, look at how each side bills. A traditional medical answering service is usually billed by the minute or per call. Asyntai is a monthly plan. Standard costs $139 a month ($125 a month with annual billing) and includes 200 voice minutes and 2 calls at the same time. Pro costs $449 a month ($404 with annual billing) and includes 1,500 voice minutes and 5 calls at the same time. Each answer the agent gives also counts as one AI reply on the plan, and Twilio bills the number and the call minutes on your own account. When every line is in use, the next caller hears that the lines are busy and is asked to call again in a few minutes.

Then look at the questions an answering service is asked that are not about health at all. Is the office open on the Friday after Thanksgiving? Which location has the lab? Does the practice take new patients? A traditional service answers what its script covers. Asyntai answers from your website, read page by page, and from the documents you upload, such as the holiday schedule. It does not invent a policy or a price. When a question is not covered, the agent offers a callback request. If a page on your website changes, update the document, or have Asyntai read the changed page again.

A practice that wants a receptionist for the busy daytime desk, with the morning rush and the lab questions, can read about an AI receptionist for a medical office. For hospice teams, whose night calls come from families at the bedside, the hospice answering service page covers the on-call nurse case. Other industries are on the answering service overview.

Switching does not have to happen in one night. Add your website, upload the after-hours policy, and write the on-call rule and the emergency rule with your physicians. Make free test calls in the browser and play the hard callers: the parent with a sick child on a Sunday, the patient who reads a phone number too fast, the caller who wants a diagnosis. Read the transcripts and sharpen the rules. Then connect Twilio, import the number and forward the weekend first. When the practice is happy with what it reads on Monday mornings, extend the forwarding to weeknights and daytime overflow.
