I found this page which mentions that the MSI can register Jitsi as a
protocol handler for sip: and xmpp: URIs:
Is that functionality in Jitsi itself or only in the MSI?
Are there system properties or any other means for non-MSI users to tell
Jitsi they want it to automatically register as a protocol handler?
If so, which platforms does it work on?
I came across various guides that describe how to manually register
Jitsi as a handler for URIs and I'm aware of how to do that, what I'm
asking about is whether Jitsi can automatically do this.
