Hey Luca -

Unfortunately, there is not a simple or easy configuration setting
that tells Asterisk to proxy the REFER request through. Generally,
Asterisk doesn't like proxying anything.

There may still be another way to handle this issue, depending on the
setup. Can you provide a bit more information about the channels on
the PBX/Adhearsion server, who sends the REFER request, and what
happens explicitly in the scenario?
