A warm transfer in healthcare is a live handoff: the patient stays on the line while the call moves to the right staff member, who gets the reason for the call before saying hello. It beats voicemail because the patient's need gets handled now, instead of starting a callback loop with a number they may not answer.
Takeaways
Four ways to hand off a call
Warm transfer, cold transfer, voicemail, or a callback task. Each fits a different moment.
Voicemail pushes the work onto a callback
And most people don't answer unknown numbers.
A good AI handoff carries context
Staff should know who's calling and why before they pick up.
When no one is free, the fallback should be a finished task, not a voicemail someone has to transcribe.
Four ways to hand off a call
When an AI or a front-desk person can't fully resolve a call, it has to go somewhere. Here are the options, in plain terms.
Warm transfer
The patient stays on the line. The call goes to a specific person or department, along with the reason for the call. The patient doesn't repeat themselves.
Cold transfer
The call is passed to another line with no context. The patient may land in a queue or a phone tree and has to start over.
Voicemail
The patient leaves a message. Someone listens later, figures out what is needed, and calls back.
Callback task
The call ends, but a written task captures who called, why, the best number, and the best time. Staff call back already knowing the issue.
See the glossary for warm transfer and IVR. IVR, or interactive voice response, is the "press 1 for scheduling" phone tree most practices run.
Warm transfer is best when someone is available and the patient needs a person now. A callback task is the next best thing. Cold transfers and voicemail are where patients get lost.
Why voicemail loses patients
Voicemail feels free, but it moves the work to later and adds a step.
First, the callback. Someone has to listen, write down the details, look up the patient, and call back. When they do, the patient may not pick up. Hiya's State of the Call 2026 survey of more than 12,000 consumers across six countries found that "86% of unknown calls go unanswered." It's a global survey, not a healthcare study. Still, a practice line the patient hasn't saved is an unknown number.
Second, the patient's need doesn't wait. A patient who called to reschedule and never got called back may simply not show up. No-shows are already a large problem. A 2020 study in BMC Health Services Research by Ruggeri and colleagues, citing earlier research, notes no-shows reach as many as 23.5% of appointments in North America and can be as high as 45% at federally qualified health centers. Voicemail doesn't cause no-shows on its own. But a call that ends without a resolution is one more patient who may drift.
Third, the details get lost. "Hi, it's Maria, call me back about my mom's appointment" doesn't say which Maria, which appointment, or which location.
How Rivvi hands calls to staff
Rivvi is a HIPAA-compliant AI workspace. On the Team plan it answers inbound calls, places outbound calls, and runs texts and a website chat widget. When a call needs a person, Rivvi has three moves.
- 1
Warm-transfer live, with context
Rivvi keeps the patient on the line and transfers the call to the right person, passing along who is calling and why. The patient does not start over.
- 2
Navigate the phone tree
If your practice routes calls through an IVR, Rivvi can work through it to reach the right department, such as scheduling, billing or the nurse line, instead of dumping the call at the main menu.
- 3
Create a finished task
If no one can take the call, Rivvi creates a follow-up task with the details: the patient, the reason, the callback number and what they asked for. Outcomes are recorded in Rivvi and pushed to a connected CRM such as HubSpot, Salesforce or Zoho.
What a good handoff sounds like
Here's a refill call that needs a nurse. The patient tells the AI her blood pressure pill makes her dizzy and she stopped taking it last week.
A cold transfer drops her at the main menu. A voicemail asks her to explain it all again to a machine. A warm transfer sounds different. The AI tells her it's connecting her to the nurse line and stays with her while it does. The nurse picks up already knowing her name, the medication, the symptom, and when she stopped. The nurse opens with the problem, not with "how can I help you?" The patient doesn't start over.
If the nurse line is busy, the fallback is a task with the same details and a time window for the callback. The patient is told when to expect the call. The nurse calls back prepared.
That's the standard to hold any handoff to, AI or human: the next person should never have to ask "what is this about?"
What Rivvi doesn't do: when your schedule lives in the EHR, Rivvi doesn't book into it or write to the chart. Scheduling goes to the person who books, live or by task. No EHR integration is needed to set this up.
| Feature | Voicemail | Warm transfer or task |
|---|---|---|
| Patient waits | Until someone calls back | Connected now, or told when to expect a call |
| Context for staff | Whatever the patient said in the message | Name, reason and details captured on the call |
| Callback needed | Always | Only when no one was free |
| Record of the outcome | Depends who listened | Recorded in Rivvi |

Office hours vs after hours
The right handoff depends on who's in the building. Set rules for both.
During office hours:
- Transfer live for anything a person needs to handle now: scheduling in the EHR, billing questions, clinical questions.
- Route by reason. Refill questions go to the nurse line or pharmacy, billing goes to billing, everything else to the front desk.
- If the target line doesn't pick up within a set time, fall back to a task rather than a voicemail box.
After hours:
- Don't transfer to an empty office. Create a task for the morning with everything staff need.
- Tell the patient plainly what happens next and when they'll hear back.
- For anything urgent, follow your practice's existing after-hours instructions, such as the on-call line, and tell patients to call 911 in an emergency. The AI should never be the last stop for an urgent clinical issue.
What to configure before you go live
Make these decisions once, write them down, and set up your line to match. Most of them are things the front desk already knows but has never written down.
- Transfer targets. List each department and the number or phone-tree path that reaches it.
- Routing reasons. Map common call reasons to departments: scheduling, refills, billing, records, referrals.
- Office hours by location. Multi-site groups often have different hours per clinic.
- Fallback timing. How long to wait for a pickup before creating a task instead.
- Task destination. Where tasks land, and who owns them each morning.
- Escalation words. Phrases that should always go to a person right away, such as chest pain or "I want to talk to someone."
- Languages. Rivvi handles Spanish and 30 more languages. Decide which staff take transfers for non-English calls.
After the first week, review the tasks and transfers. Look for calls that went to the wrong department, tasks that sat too long, and reasons that came up often but have no routing rule. Fix those, then review again a month later.
Watch one number in particular: how many tasks are created during office hours. A high count means transfers aren't getting picked up, and patients are waiting on callbacks that could have been live conversations. Look at the transfer targets and the fallback timing first.
Example: Good Years Family Medicine
Good Years Family Medicine is a multi-clinic primary care group. It went from pasting its website URL into Rivvi to a live inbound phone line and website chat widget in about two minutes. From there, the work was the list above: which clinic handles what, where transfers go, and what happens after hours.
That's the right order. Get the line live, then tune the handoffs to how your practice actually works. See how inbound works on the inbound calls page.
