@karl @gustavo22soares Basta seguir as referências após a lista de sugestões em https://jmp.chat/suggested_servers.html sobre "compliance suite test", ele testa pela #XEP agrupadora https://xmpp.org/extensions/xep-0387.html (mais atual: https://xmpp.org/extensions/xep-0423.html ) que serve como recomendação aos fornecedores de serviço sobre quais #XEP ativar. A XEP não aborda conferência ou chamadas de áudio e vídeo, neste caso o projeto Conversations pode esclarecer o que é necessário.
@strypey Offline text messaging works if one interacts through servers and clients that support the most recent compliance suites (2018: XEP-0387, https://jmp.chat/suggested_servers.html ), and optionally XEP-0077 In-Band Registration ( https://xmpp.org/extensions/xep-0077.html ) to ease users registration without requiring a web browser. To see a short list with such providers, see https://jmp.chat/suggested_servers.html (last paragraph links to more details. Also comment or share this: https://libreplanet.org/wiki/XMPP
@strypey Thanks to the grouping XEP mentioned in https://xmpp.org/extensions/xep-0387.html , the server list on https://jmp.chat/suggested_servers.html, and the compliance testers (either referenced in the last link or superior ones), people at least know which service providers are complying with XEP-0387. #XMPP
