Call Manager For Niteflirt

I'm a phone sex operator, and would like a call manager made for Niteflirt, so when I'm on a call with one persona, it would turn off all my accounts, then when the call is finished, set them all back to available. At Niteflirt, I have 11 personas, and am using a free call manager that is just for that company, but the guy that made it is unreliable and if it goes down, I'll be in a mess, as the company doesn't have a built in one like other sites do. And his runs on the computer, only works when the computer is on and the window of it is up, I want a script to run on my hosting that works 24/7 so I don't miss calls that are sent to one persona when I'm on a call with another. Please read the things in the attached file for a more through description.
