How to manage business hours, breaks and holidays on your phone system
Business hours on your phone system decide what happens to every call when you are open, at lunch, closed for a holiday or shut for something unexpected. This guide shows you how to set up opening hours and holidays, what callers should hear after hours, and the mistakes worth avoiding.
Why phone system business hours matter
Managing business hours on a phone system means deciding in advance where a call goes based on the day and time. During opening hours it reaches your team, a queue or a menu; after hours the caller hears a message and the call takes a different route. Public holidays, company shutdowns and one-off closures are exceptions to that weekly rule.
It sounds like a technical detail, yet it is one of the first things callers notice. A phone ringing out at 1:15 pm because everyone is at lunch, or a cheerful “we’re open” greeting on Christmas Day, makes a business look disorganised. A clear message telling people when you reopen and what they can do in the meantime turns a dead-end call into a handled contact.
With an old on-premise system these changes often meant calling an engineer or remembering to divert the line every evening. With a cloud phone system you write the hours once in a web portal and the system applies them to every call on its own. If you are weighing the two approaches, see cloud vs on-premise phone systems.
Weekly schedule: time slots, lunch breaks and late shifts
Everything starts with the weekly schedule. For each day you set one or more time slots when you are open; a day with no slots is closed. A lunch break is not a special case, it is simply the gap between two slots, such as 9:00–13:00 and 14:30–18:00.
Before entering anything, write the real hours down for each team, because they rarely match the hours on your website. Support may start earlier, accounts may finish early on Fridays, and an on-call service may run through the evening.
| Example | Slots to set | Note |
|---|---|---|
| Professional office | Mon–Fri 9:00–13:00 and 14:30–18:00 | Saturday and Sunday have no slots, so they are closed |
| Shop open Saturday morning | Mon–Fri 9:00–19:00, Sat 9:00–12:30 | A single slot on weekdays |
| Extended support | Mon–Sat 8:00–20:00 | Different from the sales team’s hours |
| Overnight on-call | Every day 22:00–02:00 | The slot runs past midnight |
Public holidays, shutdowns and bridge days
Exceptions are the days when the weekly schedule does not apply. An exception replaces the hours for that date: you can be closed all day or open with different slots, for example mornings only on Christmas Eve.
Holidays that fall on the same date every year are set once as recurring exceptions. Holidays that move, such as Easter and many bank holidays tied to a weekday, need a one-off exception for each year. A simple routine:
- Add fixed-date holidays once, set to repeat every year.
- At the start of each year, add the moving holidays for that year only.
- Add the company shutdown weeks, such as the summer break or the days between Christmas and New Year.
- Add bridge days and local holidays that apply only to your office.
- Add reduced-hours days with their own slots instead of closing completely.
What happens after hours: your routing options
Closing the phone after hours does not have to mean hanging up. The out-of-hours message comes first; then the call moves to a destination you choose. The right choice depends on why people usually call at that time.
The most common options, with their trade-offs:
| After-hours destination | When it makes sense | Watch out for |
|---|---|---|
| Message, then hang up | Few calls after hours, nothing urgent | Callers must try again, so say clearly when you reopen |
| Recorded audio file | You want a professional voice, for example during a shutdown | Update the file when the dates change |
| Callback request | You want to call people back as soon as you reopen | Callbacks must only run during opening hours |
| Transfer to an on-call mobile | There are genuine emergencies, such as faults | The on-call rota needs to be clear |
| AI voice agent | Many questions are repetitive: hours, address, bookings | It needs clear instructions on what it can and cannot do |
How to write a good out-of-hours message
Keep the after-hours message short and specific. Callers want to know three things: that they reached the right place, when to try again and whether there is an alternative. Skip long introductions and filler; every extra second is time spent waiting for nothing.
A good message covers, in this order:
- your business name, so the caller knows they dialled correctly;
- that you are closed right now, and why if it helps (holiday, shutdown);
- your opening hours or the date you reopen, said plainly;
- what they can do now: leave their number for a callback, use another channel, or call an emergency line;
- a short goodbye.
Unexpected closures and emergencies: the manual switch
No calendar covers everything: an all-hands meeting, a network outage, a snow day, the on-call engineer starting early. For these moments you need a manual control that changes where calls go right away, without editing the schedule.
A switch like this has two positions: on, calls go one way; off, they go the other. You place it in the call flow, for example as the number’s destination or as the after-hours destination, and each call follows whatever state it is in at that moment.
In Robottino this is the On/Off switch. Each switch has a phone code: from any company phone you dial star and the code, hear the current state and press 1 to flip it. Whoever needs to close the lines in a hurry does not have to log in to the portal.
- Emergency closure: with the switch on, every call goes to a dedicated message.
- On-call cover: a switch used as the after-hours destination decides whether calls go to the on-call mobile or to the closed message.
- Training session: the switch sends calls to a callback request for an hour instead of the queue.
Setting up hours and holidays step by step
Here is a practical sequence that works with most cloud phone systems. The names follow Robottino, but the logic is the same anywhere.
Collect the real hours
For each team, write down days, slots, lunch breaks and shifts. Ask the people who answer the phone, not only whoever wrote the hours on the website.
Create the weekly schedule
Name it, switch on the open days and set the slots. Add a second slot on days with a lunch break.
Add the exceptions
Enter fixed-date holidays as yearly exceptions, then moving holidays, bridge days, shutdowns and reduced-hours days for the current year only.
Write the after-hours message
Short, with your hours or reopening date and an alternative. Listen to it before saving.
Choose the after-hours destination
Hang up, an audio file, a callback request, a transfer to an on-call phone or an AI voice agent, depending on who calls at that time.
Attach the schedule
Link it to the phone numbers, menus and queues it should control. Make sure your account’s time zone is correct.
Test it
Place a test call inside and outside the hours and check the route. Repeat the test after every significant change.
Common mistakes to avoid
Most problems with phone system hours come from small oversights rather than technical limits. These are the ones you see most often:
- Forgetting moving holidays: Easter, bridge days and company shutdowns need adding every year.
- One schedule for every team, when support and sales keep different hours.
- An after-hours message that never says when you reopen, so callers keep trying at random.
- Leaving callbacks without a schedule, so they go out at night or at weekends.
- Never testing the route: an empty or wrong after-hours destination drops calls with no explanation.
- The wrong time zone on the account, which shifts every slot by an hour or more.
Frequently asked questions
How do I set a lunch break on my phone system?
Split the day into two time slots, such as 9:00–13:00 and 14:30–18:00. In the gap between them the phone system treats calls as after hours: the caller hears the closed message and goes to the after-hours destination.
How do I handle holidays that change date every year?
Add moving holidays such as Easter as one-off exceptions for that year only. The easiest habit is to enter them each January together with shutdowns and bridge days, while fixed-date holidays are set once to repeat every year.
What should an out-of-hours phone message say?
Your business name, that you are closed, your hours or reopening date and what the caller can do meanwhile, such as requesting a callback. Keep it short, because people call for information, not a speech.
Can I close the phone lines suddenly without changing the schedule?
Yes, with a manual switch. In Robottino the On/Off switch changes where calls go with one click in the portal or by dialling star and its code from a company phone, while your schedule stays as it is.
Can I forward after-hours calls to a mobile?
Yes. Choose a transfer to the on-call mobile as the after-hours destination. Keep in mind that calls to an external number have a cost, and that whoever answers needs a clear rota.
