In the first iteration of this SDK, 1:1 voice and video calls are supported with more advanced functionality including Messaging, simple Video Conferencing, and advanced Web Conferencing with screen share features (and much more) fast on the way. Calling SIP (Session Initiation Protocol) endpoints is supported out of the box. Making and receiving calls from a Web Browser to the legacy phone network just works. Making a call to another Web Browser endpoint has never been easier. Our Web Browser library allows developers to take full advantage of the SignalWire network and the endpoints that are contained therein.
