I want to develop the Call Barge Feature for Asterisk.
The meaning of the barge that I need is :
When there is a call exist , let's say between the local extension and some other point ... I know the number of one of the extensions and I want to enter into the conversation. So from my extension I'll press the feature key and the extension number, then some kind of conference will be created , and the conversation will be between three extensions then ...
Good example for it : Child , talking to friend too long ... I want to call him for the launch , I'm entering to the call and telling to both of the sides to talk later... Or I'm telling to the child to go for launch , he is disconnecting , but I'm stay on the line with his friend.
