[asterisk-users] Notification when queue member's phone rings

[Mitch Claborn]

Short question: how to get control or notification (gosub, macro, AGI) 
when a queue member's phone starts ringing due to an incoming call from 
the queue.

Backround:  Our phone operators serve both an asterisk call queue and a 
queue for web chat support.  I have a gosub on the queue that calls to 
our app server to mark the operator unavailable for web chat as soon as 
they answer an incoming queue call.  Similarly, when a web chat is 
connected, it uses AMI to tell asterisk to take the operator out of the 
phone queue.

The other day, one operator got a web chat that came in while her phone 
was ringing with a queue call, so that neither "remove from queue" 
operation was effective in time.  If I could get notification when the 
phone starts ringing I can reduce the window of opportunity for that by 
several seconds.

It's only happened once in 2 years that I know of, so may not be worth 
worrying about.
