Asterisk cmd NoOp

Synopsis:

No operation

Description:

NoOp()

No-operation; Does nothing.
...
Well not quite.

It can be used as a printf, or echo for the console, if your verbose level is set to 3 or higher. For example, Zap channels do not print the callerid information on incoming calls. But this works:


exten => s,1,Answer
exten => s,2,NoOp(${CALLERID})


This works with any variable, so NoOp(${any_var_name}) will print the value of the named variable on the console when that step in the extension is reached. For debugging this can be quite useful.

Note that this is a side effect of the verbosity level being 3 or higher, not a function of the application itself. The application NoOp does nothing.

If you would like output at other verbosity levels (for example, 0), you are encouraged to use the Verbose command.
