Roll-Call, p2p audio calls

Roll-Call allows free and reliable audio calls for everyone simply with a web browser.

Based on p2p, Roll-Call is an easy to deploy solution to enable audio calls. Create either your own private room or join the party and chat with the world by entering an already created room.

Simply invite friends and family by sharing a direct link, records your chats or even share an audio file (“Hey, Listen to this”).

On top of being simple to use, Roll-Call is quite simple to install as well.
