Teams switched. Here's why they stayed.
Sales, support, and ops teams came from a PBX, Google Voice, or a pile of apps.
“We took our first call 10 minutes after signing up. Now the whole team shares one number.”


We set up a new number the same day, then moved our old one over a week later. Nobody noticed a drop.

We used to miss everything after 6. Now after-hours calls go to the right person.

We replaced our old PBX in a day. Same number, less hassle, about $400 a month less.

Calls, texts, and contacts finally live in one place. I deleted three apps the first week.

The shared inbox means we don't reply twice to the same person. Our response times actually dropped.

Google Voice was fine when it was just me. Calio is the first thing that actually works for a team.
Uptime. The line stays up when customers call.
