You mean with a softphone you can't select a single (or several) video
among those available, can you ?
Even with DTMF sequence and some features.conf magic, a user cannot ask to
receive a specific video stream ?
(forgive me if my question seems naive or irrelevant but I didn't dare to
try or install anything yet)

Do you mean Asterisk receives and send SIP messages with embeded JSON
Is there a specific name for such behaviour (something that could help to
check if a SIP library or client supports this) ?
