I think at this point it's worth thinking about why we need text chats and voice/video calls integrated with each other like what #XMPP (try to), #Matrix, and #Discord do
Why not just go back to #IRC or something like #AIM for text, and something like #Skype for calls like the old days :sagume_think:
File exchange in #XMPP nowadays is either HTTP upload (covered by #OMEMO) or #jingle file transfer, which should be e2e encrypted, too, but I'm not sure about it.
Are you familiar with our #SiskinIM ? Visit https://siskin.im/ to learn more. This app is #opensource (https://github.com/tigase/siskin-im/) and serves as the ultimate #XMPP Client for iOS. It offers advanced security, spam protection, push notifications, and voice/video calls. It accommodates multiple XMPP accounts and remains compatible with any XMPP server.
Ich stiege eher von iOS auf #Mobian oder eine einigermaßen freie Android-Variante um als von #Jabber auf ein anderes Chatsystem 🙂
Gegen Matrix ist im Prinzip nichts zu sagen. Es ist frei und federiert wie #XMPP, hat aber eine Finanzierung in ganz anderer Größenordnung. Ich habe an @Monal mal etwas Geld gespendet, aber da fehlten wohl ein paar Nullen 😞
Recommendations, please, for making an #XMPP audio/video call work between:
a user on iOS and a user on Android
a user on iOS and a user on Linux
Messaging works fine, as does a/v between Linux and Android, but I have yet to find a combination which works for audio / video with an iOS device in the mix.
