That's only true when Asterisk tells the other endpoint that it is
allowed to use voice activity detection and silence suppression, which
at this point it does not do. In spite of that, there are many endpoints
that do it anyway, which then causes strange problems on calls,
including calls getting dropped if an RTP timeout is in use.
