Receive URL before Answer

Hello

I’ve got a problem. I have to forward a Url to Agents via IAX2.

I integrated this with Queue(1000,${Url})
everything works fine. The IAX Client recieves to Url when he answers the call. I’m looking for a method which allowes the Url receiving befor the call is answered. I need this feature to pop up cusomer information, so need that before the call is answered because it’s much more faster that way
