can anyone tell is there any framework like call management system in php or how can i build call management system in php?
Outbound call centre? Tracking outbound calls? Auto dialling outbound calls? What features do you need? I doubt you'll find one available for free but there is always something to buy.
Here are a few free call management websites you can check out..don't know if they offer exactly what you need though: telwise.co.uk and switchboardfree.co.uk
