What is a browser dialer?
A browser dialer is a phone keypad that runs inside a web page. It uses WebRTC, a standard built into modern browsers, to carry your voice over the internet to a calling network that connects to ordinary phone numbers.
For your team, that means a headset and a laptop are all they need. New starters can make calls as soon as they can sign in, and people working from home use exactly the same phone system as those in the office.
