[asterisk-users] Variable using AMI

["Juan E. Rodríguez"]

Well, I do not understand very well what you are trying to do, but I'll 
give you some advice:

If you want a variable only for the AGI you call, you just have to 
declare that variable on the AGI.
If you would like to make visible that variable as long as the call is 
active and for each call, even if the name is the same, you have to set 
a channel variable with the Set(variable=value) command.
If you would like to have a variable shared between two or more 
channels, use the SHARED() funcion(Asterisk 1.6, back ported to 1.4)
If you want a variable to be accessed from all the channels, you could 
use a global variable.
