After-hours emergency dispatch: how a live answering service gets the right person on a 2 a.m. call

Published October 26, 2026 by Special Interest Answering Service (SIAS), Joliet, Illinois. Call volumes are from SIAS's own switch records, July 1 to October 18, 2026. The workflow describes how SIAS dispatch accounts are built; other services differ in the details, so use this as a checklist of questions.

"Emergency dispatch" is the part of an answering service that matters most and is explained least. A service that only takes messages is a voicemail with manners. A dispatch service decides, on the call, whether the problem can wait until morning, and if it cannot, finds a human on your side and connects them. This guide lays out the pieces of a working dispatch setup, what a business has to decide before the first call, how operators work the on-call list, and what it costs, with numbers from about 248,000 SIAS call records.

When the calls come in

Across every SIAS account, about 40% of operator-handled calls arrive outside Monday to Friday, 8 a.m. to 5 p.m. That breaks down as roughly 24% on weekday mornings before 8, evenings and nights, and 16% on Saturdays and Sundays. Weekday evenings from 5 to 10 p.m. alone account for about 16% of the week's calls. The busiest single stretch of the week is Monday from 7 to 9 a.m., when the weekend's problems reach the phone at once: Monday call volume in those hours runs 15 to 25% above the Tuesday-to-Friday average.

Shares are computed from the average handled calls per hour and per weekday in the SIAS call export, July 1 to October 18, 2026, all accounts combined. Dispatch-heavy accounts (contractors, property managers, medical practices) skew further toward nights and weekends than this all-account average.

The five pieces of a dispatch setup

1. The definition of an emergency

Operators do not decide what counts as urgent; you do, in writing, by trade. The definition is the single most important line in the account because it decides who gets woken up. Typical definitions SIAS accounts use:

• HVAC: no heat when the outside temperature is below a threshold you set, no cooling for a customer with a medical need or a commercial account, a gas smell (which the script routes to the gas utility or 911 first, then to you), water from the unit.
• Plumbing: active leak that cannot be shut off, sewer backup, no water to the building, water heater failure for a multi-unit building; a slow drain waits.
• Property management: no heat, no water, flooding, fire or smoke (911 first), lockout, broken exterior door or window, elevator entrapment (911 or the elevator company per your instructions); a dripping faucet waits.
• Medical and dental: whatever the practice defines, usually a patient reporting specific symptoms, a post-procedure complication, a pharmacy or hospital calling, or anything the caller insists is urgent; billing questions and appointment requests wait.
• Law firms and real estate: usually no life-safety emergencies, but "reach me now" rules for new-client intake, a closing in progress, or a named existing client.

2. The on-call schedule

Who is on call tonight, this weekend, next week. Some businesses send a monthly rotation; some change it by calling in on Friday afternoon; some have one person forever. Operators work from the current version of the account, so a change takes effect as soon as it is entered. At SIAS there is no fee for schedule changes, and they can be phoned or written in at any hour.

3. The escalation order and contact methods

For each on-call person: which number to call, whether to text or page first, how long to wait for a response, and who is next. A common HVAC pattern is: text the on-call tech with the job details, wait ten minutes, call the tech, then call the service manager, then the owner. A common medical pattern is: page the provider on call, wait a set number of minutes for a callback, page again, then call the backup provider.

4. The information to collect

The script tells the operator what to ask so the on-call person can act without calling back for basics. For a contractor: name, callback number, service address, what is happening, when it started, equipment type if known, gate codes or access instructions, whether the caller is an existing customer. For a property manager: property and unit, tenant name and number, the problem, whether anyone is in danger, whether the tenant has shut off water or power. For a practice: patient name, callback number, a short statement of the problem in the caller's words, the provider the patient sees, and nothing more than the practice needs (the minimum-necessary idea from HIPAA applies to the script itself).

5. The fallback

What the operator does if nobody on the list answers: keep cycling the list, try a last-resort number, tell the caller the next-business-day plan, or, for life-safety situations, direct the caller to 911. A dispatch setup without a written fallback is where the worst failures happen, because the operator is left guessing at 3 a.m.

What happens on the call

1. The call forwards from your line to the service (always, after hours only, or only when busy or unanswered; carrier codes are on SIAS's How to forward page).
2. A live operator answers in your company name, 24 hours a day, including holidays. At SIAS the operators are US-based and bilingual in English and Spanish.
3. The operator asks the script's questions and checks the caller's problem against your definition of an emergency.
4. If it is not an emergency, the operator takes a message and delivers it by text, email or fax, or through a secure app, for the morning.
5. If it is an emergency, the operator works the on-call list in your order: text or page with the details, call, wait the set interval, move to the next person. Or, if you prefer, the operator patches the caller straight through to the on-call person while the caller is still on the line.
6. When someone on your side has the job, the operator closes the loop: the caller is told who is coming or calling back, and the dispatch is logged with the time and the person reached.
7. If nobody answers, the fallback instructions run.

What dispatch costs on a per-minute plan

Dispatch calls use more operator time than a plain message because the operator makes outbound calls, pages and texts on your behalf. At SIAS, billed time includes the conversation with the caller, setting up a patch, the outbound calls to your on-call list, and sending the messages and pages. Not billed: ring time, time in your greeting, and the talk time after a caller is patched through to your tech, which can be the longest part of an emergency call. Across all accounts the average handled call used 82 to 90 seconds of operator time in 2026; a full dispatch with two or three outbound attempts runs longer, so a company with many emergencies should expect to land at the lower end of the 65-to-75-calls-per-100-minutes range, or a plan up.

SIAS plans run from $159 every 4 weeks for 100 operator minutes ($0.99 per extra minute) to $960 for 1,200 minutes, with no setup fee, no contract, and plan changes effective the next cycle at no fee, so seasonal companies can move up for the winter and back down in spring.

Setup checklist: what to send the service

• Your emergency definition, by call type, in one or two sentences each.
• The on-call rotation for the next period and how you will send changes.
• For each on-call person: name, mobile, preferred first contact (text, page, call), wait time before escalating.
• The escalation order and the last-resort number.
• The fallback if nobody answers, including any 911 or utility instructions.
• The questions to ask callers, and anything the operator should never say (pricing, arrival times, medical advice).
• Where messages go for non-emergencies (text, email, fax, secure app) and who gets copies.
• Your forwarding plan: all calls, after hours only, or busy and no-answer only.
• A test: forward the line, call it yourself after hours, and walk through an emergency and a non-emergency.

Four mistakes that cause missed emergencies

1. A vague definition. "Call me if it's important" leaves the decision to a stranger. Name the situations.
2. A stale rotation. The tech who left in August is still first on the list in November. Put schedule changes on a calendar.
3. One number per person. Phones die and go to voicemail. Give a text and a call path and a second person.
4. No fallback. Decide now what happens when nobody picks up, so the caller is never told "someone will call you back" with nobody assigned.
