A real off-hours boundary.
Set hours per day of the week. Mark holidays for the year. The auto-attendant, hunt groups, IVR, and per-user routing all respect the schedule automatically — in-hours rings the right destination; out-of-hours routes to a custom voicemail or after-hours number. No manual switching required.
Working hours on Kelir.
Working-hours routing is the layer that makes every other call-handling feature time-aware. Auto-attendant plays a different greeting in-hours vs out-of-hours. Hunt groups only ring during business hours; outside that window, calls route to voicemail or an after-hours destination. IVR menus can branch to different routing per option per time-of-day. Per-user direct lines can ring or go straight to voicemail based on whether it's working time.
On Kelir, working hours configure at three levels: per user (each individual sets their own work schedule and the system respects it on their direct line), per department (Sales 9–6 weekdays, Support 8–8 weekdays plus Saturday morning, Finance 9–5 weekdays only), and company-wide (the default for the auto-attendant and main-number routing). Per-user and per-department settings override the company-wide default where they're set.
Configuration uses per-day schedules — different hours Monday vs Saturday are normal, not exceptional. Holiday overrides mark dates on the calendar (Memorial Day, Thanksgiving, Christmas Eve, Christmas Day, the long weekend in November, your local civic holidays), each routing to a holiday greeting and behavior automatically. Set the year's holidays once in late October; the system handles the rest of the year unattended.
RingCentral, Dialpad, 8x8, Vonage Business, and Nextiva all ship comparable working-hours functionality. Functionally similar; differences sit in plan availability (Kelir Solo includes working hours at $24.99/seat where competitors typically gate it behind a mid-tier plan), in surface (configurable from the Kelir mobile app, not just the web admin), and in what happens at the cellular line when the schedule says "don't ring" — the line just doesn't ring.
Setup walkthrough.
Configured from Mobile app. The setup below assumes a working Kelir account and an active eSIM.
- 1
Open the Kelir mobile app and tap Settings → Working hours.
- 2
Set per-day hours: Monday 9–6, Tuesday 9–6, … Saturday 10–2, Sunday closed. Tap any day to edit independently.
- 3
Pick the in-hours behavior — typically just "ring my line". Override per user if needed (Sales rings the sales hunt group, etc.).
- 4
Pick the out-of-hours behavior: route to voicemail with a custom greeting, forward to an external number (an answering service, a personal cell, a paging service), or play a busy tone.
- 5
Configure the holiday calendar — tap Holidays, mark dates for the year, pick the holiday-specific behavior (typically a holiday-closed greeting and route-to-voicemail).
- 6
On Team plans, configure per-department hours from app.kelir.io — each department has its own schedule that overrides the company default.
- 7
Save. The next inbound call respects the new schedule.
Where working hours earns its keep.
Solo professional with evening boundary
Hours: Mon–Fri 9–6 ET. After-hours rings to a voicemail with greeting ("You've reached Sarah Chen — I return calls Monday morning"). Real boundary, the line goes silent at 6.
Clinic with split provider hours
Practice main: 9–5 weekdays. Provider A (Mon/Wed/Fri 8–4): individual hours. Provider B (Tue/Thu 10–6, Sat 9–1): individual hours. Each provider's direct line respects their own schedule. Practice main routes to the on-call hunt group on weekend.
Contractor with after-hours emergency line
Crew dispatch: 7–6 weekdays plus Saturday 8–12. After-hours, calls route to an emergency-only number (an answering service that pages out for true emergencies). Holidays route to the same emergency line plus a holiday greeting.
Holiday week setup in late October
Mark: Wed before Thanksgiving (early-close 1pm), Thanksgiving (closed), Friday after (closed), Saturday-Sunday (closed), Monday (resume normal). Five clicks; runs automatically through the holiday week.
Time-of-day branching in the IVR
IVR option "Press 1 for sales": in-hours routes to sales hunt group; after-hours routes to sales-team voicemail with a greeting that promises a Monday-morning callback. Same digit, different behavior, controlled by working hours.
The same feature.A real cellular line.
Working-hours routing is table-stakes UCaaS. The differences sit in plan availability, configuration surface, and what happens to the line itself outside hours.
- Working hours are included on Kelir Solo single-seat ($24.99/mo); softphone competitors typically gate it behind their business mid-tier plan ($25–35/seat).
- Configurable from the mobile app — change the snow-day greeting from your phone the morning of, no laptop required.
- Per-user, per-department, and company-wide schedules layer cleanly. Per-user override beats per-department, which beats company-wide default.
- Out-of-hours, the cellular eSIM line just doesn't ring — there's no app to mute, no Wi-Fi-routing setting to flip, no "available status" to manage in a softphone UI.
- Holiday calendar handles dates years in advance. Set Memorial Day 2027 in October 2026 and don't think about it again.
- Schedule changes take effect on the next inbound call, not at the next "sync" or "refresh".
Common questions
Yes — and they should. On Solo, you set your own hours and they apply to your line. On Team plans, each user sets their hours from the mobile app; admins can override or set defaults from app.kelir.io. Hours layer cleanly: per-user beats per-department beats company-wide.
It doesn't ring. The Kelir routing platform evaluates the schedule before ringing the eSIM. Outside hours, the call routes to whatever you configured — voicemail with a custom greeting, forward to an external number, or "call back during business hours" prompt. The cellular line itself stays active (so you can still call out, and personal-SIM calls continue normally), but inbound calls to the Kelir line don't ring.
Holidays are dates marked on the calendar that override the regular schedule. Each holiday can have its own behavior — typically a holiday-closed greeting plus route to voicemail. Mark the year's holidays in late October; the system runs them automatically as they come up.
Yes. Per-day schedules are the default — Monday 9–6, Tuesday 9–6, Wednesday 8–7, Saturday 10–2, Sunday closed are all routine configurations. Edit any day independently from the mobile app.
The active call continues normally. Working hours only affect new inbound calls — the schedule check happens at the routing-platform level when a new call arrives. An ongoing call is ongoing.
Yes. Add the day as a one-time holiday with a specific behavior (or an early close), runs once, then reverts to the regular schedule. Doesn't require modifying the recurring weekly hours.
