Can I set different call routing rules for after hours and weekends?


About the Author
Yes. With a modern VoIP system, you can set up time-based call routing rules that automatically send calls to different destinations depending on the day and time they arrive. That might be a mobile, voicemail, an on-call team, or a custom message. The rules run on a schedule you set once in your online portal, then they work in the background continuously.
What Is Time-Based Call Routing?
Time-based routing, also known as schedule-based routing, is a standard feature in cloud VoIP systems. It lets you define exactly how incoming calls are managed depending on the day and time they arrive. Think of it as a set of automated rules your phone system follows. Typical examples:
- Monday to Friday, 9am to 5pm, calls ring to your head office team.
- After 5pm on weekdays, calls redirect to a mobile or voicemail.
- Saturday and Sunday, callers hear a custom out-of-hours message with an option to leave a voicemail.
- Bank holidays, calls route to an emergency contact or a recorded message.
All of this is configured in your online management portal. No engineer visit, no complex hardware.
Why Does Call Routing Matter for UK Businesses?
Missed calls are expensive. Callers who reach voicemail outside office hours often do not leave a message. They call a competitor instead. With after-hours routing in place, every caller gets a professional, informative experience rather than a dead ring or an abrupt end to the call.

For businesses in sectors like healthcare, legal, property and trade services, after-hours call handling is especially critical. A potential new client calling at 6pm on a Friday should not be met with silence.
How Do I Set Up After-Hours and Weekend Routing?
Most cloud VoIP providers offer an online portal where you can configure everything. The standard pieces are:
Business hours schedules, where you define core working hours for each day. You can set different hours for weekdays versus weekends, or create separate schedules for different departments.
Custom voicemail and greetings, so callers hear a professional after-hours message telling them your opening times and what to do next. Update these instantly from the portal whenever they need to change.
Redirect to mobile, using a mobile or desktop app so your team can take calls anywhere. Out-of-hours calls can ring directly to a manager's mobile using the same business number. For more on this, see our mobile VoIP guide.
Auto Attendant (IVR), which works together with time-based routing. Out of hours, callers can hear a menu such as "Press 1 to leave a voicemail, Press 2 for our emergency line".
Holiday routing, where you pre-set call rules for Easter, Christmas or any bank holiday in advance, with no last-minute changes needed.
How Do I Handle Weekend Calls Without Weekend Staff?
Many SMEs operate with reduced or no staff at weekends. With weekend-specific routing, you can:
- Send all Saturday and Sunday calls straight to voicemail.
- Route weekend calls to a dedicated on-call number.
- Use an AI receptionist to answer and qualify calls if your provider offers one.
- Play a tailored weekend message with alternative contact details.
- The flexibility is entirely in your hands, and any changes take effect immediately.
What Does Good After-Hours Routing Look Like in Practice?
A busy estate agency might set up the following:
- Monday to Friday, 9am to 6pm, calls ring to the sales team queue.
- Monday to Friday, 6pm to 9pm, calls redirect to the duty manager's mobile app.
- Saturday, 9am to 4pm, calls ring to a Saturday duty team.
- Sunday and after 4pm Saturday, calls go to voicemail with transcripts emailed to the team.
The result is no missed enquiries, no frustrated callers, and a team that is not disturbed unnecessarily out of hours.
What Should I Check Before Choosing a Provider?
Look for a provider whose portal lets you self-manage these rules without raising a support ticket. Most cloud VoIP systems include time-based routing as standard, but the depth of control varies. The key things to check:
- Can you set different schedules per department or extension?
- Can you create routing rules for bank holidays in advance?
- Can you record and update voicemail greetings yourself?
- Is there an Auto Attendant included, or is it an add-on?
- Can your team take calls on mobile when calls are diverted?
