Adapted from Asterisk variables - voip-info. A variable name may be any alphanumeric string beginning with a letter. If you define a channel variable with the same name as a global variable and remember: user-defined variable names are not case sensitivereferences to that variable name will return the value of the channel variable.

Shared function sounds to solve the problem, however i am not sure if it could pose any possible variable mixing when there are concurrent calls.
Say incoming call1 and call2 happen at the same time. Call1 gets a shared variable "op" assigned to channel1 and i end up using this for channel2 as well. Apparently Shared didn't work. This doesn't work since the Shared value is retrieved against the current channel and I don't have a way of carrying the channel1 details right across to channel2 - so that i can end up using SHARED operator,channel1 for both setting and getting!
Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. Guess what? My question is this: how is this channel variable already set before the dialplan starts executing? It turns out that there's a way to set global variables in Asterisk, and when you go to request a variable for a channel, the global value will be shown if the variable has not been set otherwise on the channel.

The G option in Dial is one of those fun options that sends the two channels involved in the Dial operation to different places. That is, I'd expect the called party to start executing at calledContext,s,2 and the calling party to start executing at calledContext,s,1.
But that's ancillary to your issue.

As soon as one of the requested channels answers, the originating channel will be answered, if it has not already been answered.
These two channels will then be active in a bridged call. All other channels that were requested will then be hung up. Unless there is a timeout specified, the Dial application will wait indefinitely until one of the called channels answers, the user hangs up, or if all of the called channels are busy or unavailable.
Dialplan execution will continue if no requested channels can be called, or if the timeout expires. This application will report normal termination if the originating channel hangs up, or if the call is bridged and either of the parties in the bridge ends the call.

Execute via Gosub the routine x for the called channel before connecting to the calling channel. The subroutine is executed on the called channel after it is answered but before it is put into a bridge with the calling channel. The 'connecting' phrase there refers to the act of bridging the called channel with the calling channel. Evaluate Confluence today.

Of course you can use it and for other purposes. When you have installed and working Asterisk PBX you will need some user to test this application. If you do not have any registered in iax. If you are not going to user Idefisk Softphone and iax. So, we have registered the users anatoliyuser1 and user2. We now have a user that can use the context [test] from extensions. So now we need some dial plan application in [test] in extensions. Here is the application in extensions. If you see unknown so far applications for you have a look at the following tutorials: Answer.
Here is what you will see in CLI. The channel there is answered and again the variables are dumped and the channel is closed.

That does not seem to work at all, when getting the value from within the dial plan, it is empty. First, the global variable must not be declared in the dial plan under the [globals] section. And, it seems you cannot set a global variable from within an AGI script.
However, you can set a channel variable local to the current channel. So to set a global variable from an AGI script, you first set the value to a channel variable and when you return from the script into the dial plan, you retrieve the value of the channel variable and assign it to a global variable. Basically, it seems you can only assign global variables from within the dial plan, not from within an AGI script. Asterisk wiki info about AGI says different things about global variables Global variables are not passed to the AGI script in this manner.
You must get them using the "get variable" AGI command Does not work with some variables that are generated by modules Learn more. Asterisk AGI: How to get or set the value of a global variable? Ask Question. Asked 8 years, 6 months ago.Asterisk Tutorial 58 - Asterisk AMI Originate Dial [english]
