Hello all,
I am interfacing sim900 modem with PIC micro-controller. When I make a call from sim900 & reject it at other end I don't get any response before the timeout period set by ATS7(which is by default 60 sec). After time out it gives response as NO ANSWER. I need to get it as soon as the call is rejected from other end. Which settings are required for this?
 

at + moring (status of originated call)
Read AT commands doc for details
