gsm returns IDLE status in some cases

[GoogleCodeExporter]

Hello guys. 
I've been working on an interfacing system of GSM Shield SM5100-B with Arduino 
UNO Rev 3. and a keypad and an LCD. 

when I used the example to send an SMS from the Arduino statically it worked 
fine and I received the sms. also, I succeeded making a call. 

the code I used to make the Call is attached called callCode.

what happened, not changing anything in the hardware configuration, I just 
uploaded the code that assembles all the parts in the system. this code is 
attached called finalCode. I faced the Message saying 
"SIM900 doesn't answer. Check power and serial pins in GSM.cpp status=IDLE"

Note: I've supplied the circuit with a 5 V and 2 A power source attached on the 
GSM shield to get the connectivity to the mobile operator network. 

I am using Arduino 1.0.3 IDE and the updated library of GSM Shield.

Any Help !
