Chat using SIP/XMPP
Hello, I currently have three Jami clients (latest nightly version on Ubuntu 18.04), and they are all connected to the same SIP exchange (specifically: FreePBX 15 based on Asterisk 16). I'm using Jami as a SIP client in order to do video-conference calls between the three clients, and everything works well so far.
However, I noted that the clients are not able to send text messages between them, so my question is: does Jami support chat via SIP and XMPP? If yes, how can I configure it on Jami?
NOTE: I've already enabled chat/XMPP support on FreePBX for all three users (following this guide).
NOTE 2: in case Jami does support XMPP, the problem could be a misconfiguration of FreePBX (in particular, the XMPP domain, that is currently blank). I have little knowledge of XMPP on FreePBX, so maybe some of you know how to configure FreePBX in order to enable chat support in Jami.
Thanks very much.
