TODO

A lot! For example, implementing direct chat (in normal calls, outside conferences) in VERTO.

In SIP.js, print in the chat textarea the message sent during "normal" calls (sending, receiving, and displaying of the received message is already working).

Polishing and homogenize it all

Adding button, menus, and commands to manage conferences layouts, moderator duties, screen sharing, and the like.

Have a more robust management of call failures, and a robust clean it up when things go awry.
