XMPP
Secure voice, video, chat and attachments (XMPP)
You have a federated chat account using XMPP protocol. You can make voice and video calls, send text messages and attachments to anybody with an XMPP account. Tens of thousands of XMPP servers run around the world, and you can communicate with anyone who has an account on any server (like email). You can also create group chats.
You will see a tile called Movim within Ravergram.club portal. You can use this for chats, calls, and even social media. You may want to install client software on your devices to have more features for XMPP such as notifications. Get an app here. Your friends can get a free account here.
Your account is yourusername@ravergram.club and password is what you set in the main portal page.
If you have an Android compatible device, you can tie your phone number to the account to be used for regular calls and SMS. Checkout https://jmp.chat/. I pay $5/month per phone number and $5/month for my data SIM card. This is a cheap and secure phone service.
Limitations
- Group calls are not possible. You can create a group call in Nextcloud Talk and send people the link for that.
- I do not recommend using End to end encryption with XMPP. It is possible but will encrypt on a single client. The client is the software you installed on your device such as Conversations or Gajim. You will not be able to see those encrypted messages from another client. Communications are always encrypted to and from the server, and I do not look at anything stored on the server.
