[asterisk-users] Macro and Arguments

[bilal ghayyad]

Dear James;

Thanks a lot for your kindly help and reply.

Here is the question: what is the CONSOLE variable
that is related to the channel? What it means and to
what it indicates this variable?

So when we say that Console/dsp, what does that mean?

Because console term is related to the console used
with the asterisk command that we connect to it using:

/usr/sbin/asterisk -r

So what is the diffrenece between this and the console
variable related to the channel?

Regards
Bilal

Correct.

Using ${CONSOLE} relies on magic - it looks for a
channel variable, and
 when
one is not found, it falls back to the global var.  If
CONSOLE happened
 to
be defined on the channel, it would be returned
instead of the global
 var.

Using the GLOBAL dialplan function lets you get at
global variables
 whether
or not direct access to them is occluded by a
like-named local or
 channel
variable.
