Hi. it's possible to get a var used in extensions.conf? or are there any way to make something like?

Yes, use
var x = GetVariable(var_name)
It will return variables from the dialplan.

Hi skrusty... Thanks for answerd to me..

Ok, I'll try it... One thing.. Do you know if it's possible use your library with windows xp?
I'm using with windows 7, but for now, in windows xp, I'm using Asterisk.NET library...
It's possible?

You may need to download the source, and compile against .NET 3.5, as I am unsure if the current target (4) is compatible with Windows XP.

Hi... ok, I thought that you use .NET 4.5 (not compatible with XP)...

One question.. I wanted to use the var to differentiate between normal incoming calls (SIP/10 for example), and queue incoming calls (Local/10), you know?

Do you know if there are any way, any event to differentiate it?

I thought that use it:

exten => s,1,Set(MyVar=1)
exten => s,n,Queue(example)
exten => s,n,HangUp()

I could differentiate, but when I consult (Getvariable), always I have 1....

Can you think any way to do this?

Thanks a lot!!!!1

I just compiled the source against .NET 2.0 today, only had to remove some using's in a couple of files, no other issues.

Frankly I don't understand why it's announced that this project is .NET 3.5 or 4.5. Especially for a library, it's nice to keep the .NET version as low as possible, as it makes it impossible to include into projects if the framework version is higher than the projects.

Thanks phox,

I do understand your point and it's under consideration at the moment. It's the state it was in when I inherited it. assuming it causes no issues (i don't think it will) I am to do this soon.

Ok, thanks for all.... Finally I fix it using New_state_event and dialevent..

Thanks for all!!

I created the thread with the similar question. I'm still having difficulties with the following piece of code:
var x = GetVariable(var_name)
what context it should be used in?

For example, the code below:
 private void dialButton_Click(object sender, EventArgs e)

            var x = GetVariable("${EXTEN}");

produces the following error:

The name 'GetVariable' does not exist in the current context.

GetVarialbe is a method for AGIScript, not AMI (Asterisk Manager Interface).

GetVariable returns variables that are in the current scope of a call, like 'DIAL_STATUS' etc.

If you want to get a Variable from the AMI, you need to call the GetVar Action.

When a variable is set, there's an event you can listen to in AMI called 'VarSetEvent'.

Hope this helps.

Thank you, Skrusty!

Would you be so kind and give an example of the code? I'm trying to implement that simple functionality which I described in the other thread but can not figure out how to use C# with both framework and AGI.
