I haven’t hosted my own matrix server yet. is it safe to join an instance? I don’t really know how private that would be. the question is when I signup/login would I be giving out my IP? is the metadata private? sorry for asking this, I’m just a bit paranoid
How is XMPP compared with SIP+SIMPLE in that?
Could you explain a bit better what you mean? SIMPLE might be somewhat comparable purely as a protocol, but for all practical purposes is isn’t comparable to XMPP as there are no good clients and no federated network.
There is federated network and good client. Linphone is an example. Jitsi (not Jitsi Meet) is other.
You can send messages to any SIP account using SIMPLE.
Weeeelll, technically. But there is no where near the same ecosystem as for XMPP. Also I don’t think there is e2ee for SIMPLE.
There is, it is called LIME.
Every business here use SIP-Phones (calls only though), mostly with propietary implementations but is something very extended at business and institutions level.
Yes I am aware that there are a lot of SIP phones, but are you seriously comparing that to XMPP? That is like saying WhatsApp is the same as snail-mail :p
Jejejejejeje.
BTW, LIME is specific from Linphone though.

I make the comparison because they don’t add modifications to the protocol itself. These closed networks use to be compatible with any SIP public infraestructure in comparison what people do with XMPP which even being connected, there could be a lot of incompatible things.
I consider SIP and SIMPLE simplicity a feature in comparison with other protocols.
BTW, SIP can be used P2P as well as SIMPLE. If I remember use to be mostly that with STUN help and a SIP Proxy Server for registering users and notifications.
XMPP does calls as well: https://blog.wirelessmoves.com/2020/05/xmpp-voice-and-video-calls-with-conversations-a-dream-come-true.html
You could also combine an XMPP server you manage with something like Asterisk to then allow your XMPP clients to do SIP calls through that, though that is a bit involved.
The XMPP calls are set in Jingle XEPs. AFAIK, there are big stability issues even with the XEPs for STUN/TURN discovery.
Your experience may vary, but on my personal XMPP server with it’s own STUN/TURN server using conversations.im - calls pretty much Just Work (edit: I’ve only tried a call with a siskin client outside of conversations and that worked too).
