Roll Call is a completely free🎉 voice chat service with podcast quality recording.
This page answers common questions and explains how to use all the "hidden" features in Roll Call.
You can click the start link on the front page, or just clickto start a new call.
You can invite other people to the call simply by sharing the URL with anyone you'd like to have join. You can also modify the URL's room paramater to create something more permanent that you and your friend can continue to return to.
You're probably used to hearing short delays and clipping as the audio adjusts to bandwidth conditions when using online calling tools. When you record a call on Roll Call it does not record the audio you're hearing, which is optimized for latency.
Roll Call records every participant locally and sends that audio to the person who intiated the recording. You'll notice when you initiate a recording that each the element for each participant shows the status of their recording. That includes the data transfered in real time.
Browsers are limited in the formats and bitrates they can record. But the largest loss in quality during recording comes from the tradeoffs of maintaining a realtime call, which we avoid.
Roll Call uses WebRTC, a peer-to-peer realtime standard for browsers. This means that the infrastructure for the calls is minimal and only used for signaling. The bulk of what would normally cost money, like hosting fees, are unnecessary since it's peer-to-peer, so this project remains free and entirely Open Source.
However, you can support the development of this project on Patreon. This helps sustain the project and prioritize it over other open source work.
