Calling from a Linux Browser, Step by Step
A few quick steps and your Linux workstation is placing calls at low per minute rates.
Pick a Supported Browser
Chrome, Chromium, Firefox, Brave, and Edge all work. Keep the browser current so WebRTC stays stable.
Grant Microphone Access
Say yes when the browser asks to use your microphone. No prompt? Review your PulseAudio or PipeWire settings along with the browser site permissions.
Log In and Dial
Sign in to Intercalling, key in the number, and press call. We link your browser to the public phone network so any mobile or landline is reachable.
Fixing Audio on Linux
No sound? Open your system sound settings and check which input device is selected, make sure PipeWire or PulseAudio is running, and confirm the browser can reach the microphone. For browser quirks, clear permissions and reload the page.
Sorting Out Linux Voice Problems

Latency
