[asterisk-users] Routing premature media to the calling channel

I want to have the early media to pass from the provider down to the soft
phone because it contains important information about the call, like "Your
call cannot go through, please try your call again " ... The provider is
giving this info via early media, just after the 183 SESSION PROGRESS.
