This is some code for call queue monitor, as mentioned here: http://www.freepbx.org/forums/viewtopic.php?t=2612
This is the first iteration and it's currently rather basic, although it does work. It used the AMI to read the call queue information and then uses a couple of regex's to work out the number of calls answered, the number of calls abandoned and the name and number of people waiting in the queue.
After a predetermined amount of time, the name and number will be highlighted in pink, to show it's getting urgent to answer that call, and after a little longer, it will turn red.
The code uses Prototype for the ajax updates because I'm familiar with it. It's complete overkill for this function, but it works.
The attached file includes everything needed. Extract to a new directory in the webroot and open it in a browser.
There's no license on this code - do what you like with it :)
