Fribse,

I think your confusion might be from the purpose of the bind_meta_app
application. The *1 or *2, etc. must be dialed after the call has been
established. In other words, bind_meta_app sits there on an existing call,
listening for *1 or *2 (etc.) and if the person on the appropriate call leg
dials it then the application in bind_meta_app gets executed. Example:

<action application="bind_meta_app" data="2 b s
record_session::$${recordings_
dir}/${caller_id_number}.${strftime(%Y-%m-%d-%H-%M-%S)}.wav"/>

The "2 b s" part of that means: Listen for *2 on the b leg and execute the
app on the s leg. So, the b leg could dial *2 and it would initiate call
recording.

Let's take a step back... are you sure you need bind_meta_app? What exactly
is your use case here? In general terms, what are you trying to accomplish
with your dialplan extension?
