# How to set your alert hours so business calls ring only when you're working

Alert hours keep your phone quiet when you're off. Outside your hours, business calls don't ring you and texts and voicemails arrive without a sound, while teammates who are working still get them. This guide shows you how to set your weekly hours, give a line its own hours, set a teammate's hours as an admin, and change your hours from the phone app.

## Questions and answers

### What happens to calls outside my alert hours?

They don't ring your browser, phone app, or desk phone. They still ring teammates who are inside their hours. If nobody on the line is available, the caller goes to voicemail.

### Do I still get texts and voicemails after hours?

Yes, they still arrive in the app and on the website. You just aren't alerted with a sound or notification until your hours start.

### How are alert hours different from business hours?

Business hours are set by an admin for a whole line and send every caller to voicemail when the business is closed. Alert hours are yours alone and decide when you are alerted. Both apply. See Business hours.

### Can I work different hours on different lines?

Yes. Under By line, choose Custom hours for this line and set that line's own days and times, or Alert me at any hour for a line you always cover.

### Can an admin change my alert hours?

Yes. Admins can set any teammate's alert hours from Team, for example to cover a shift.
