It says SIP supports instant messaging. Never knew that. I wonder why it is not a popular protocol for all these "instant messengers" out there (especially since it also support P2P)? How does it compare to Matrix?
- Arathorn 3y agoSIP’s instant messaging support and capabilities are basically the same as SMS. You can also negotiate MSRP over it, which adds group chat, which is what RCS does (the thing Google Messages speaks), but stuff like scrollback and e2e encryption is missing. It also doesn’t put an emphasis on extensibility, unlike XMPP & Matrix.
- tinus_hn 3y agoBecause it’s only one to one messaging which is a solved problem. The instant messengers are about group chat and public messaging.
- fulafel 3y agoProtocol popularity is like programming language popularity. It's not enough to be technically competent (though I don't know if SIP is). You need marketing, big enough mindshare/uptake for network effects to kick in, cultural background match (telco world in the case of SIP), a "killer app", etc.
