A team phone system,
where you already work
Calls, voicemails, and texts, all in the channels your team already uses. Pay per number, not per teammate.
No PBX. No IT project. Up and running in minutes.
Works in Slack
Calls and texts come straight into your Slack workspace. Your team responds like any other message.
Real phone numbers,
real desk phones
Get a local number instantly. Route calls to SIP desk phones, Slack, or both. Customers get a professional experience; your team gets flexibility.
It Just Works
No dedicated IT person required. Hotliner is designed so that anyone can set it up, manage it, and hand it off.
All without touching a single config file or line of code.
Built for Teams Like Yours
Whether you run a business, an event, or are trying to do something else that just needs a number: your team deserves a real phone line.
Hotliner was built around two simple ideas: customers should always be able to reach you, and your team should be able to respond, without chaos.
Small Businesses & Organizations
Get a dedicated business number that any team member can respond to, right from Slack or a desk phone. Set business hours, route calls to the right person, and never miss a customer again, without anyone giving out their personal number.
Solo Professionals and Individuals
Get a dedicated second number for calls and texts. Use it for work, give it to clients, or replace your landline entirely, and manage everything from the device you already have. When you’re off the clock, you’re off the clock.

Hotliner costs a fraction of what our landline used to, all while making it easier for us to access our calls when away from home.
