Hi 
I am trying to execute code every X min in active calls and I cant seem to find any way to do this. I basically have a function  that checks if the user has balance and permission to carry on the call and the callback should trigger it every X mins. 

The  call_control module doesnt work for me since
A. It doesn't trigger a function it just ends the callback
B. it uses an external application to calculate it 

any advice is appreciated
