We need Programme for telecom. -- 8

I need to make a campaign per month. Customer will subscribe by sms keyword and long code (automatically generate by the system for billing). After subscription, the system must plan three automatic calls(choose random recording voices and play it) ) in the month. I need also a billing management in the system.
