Can not call GPRS Shield

[szotyi]

Hello!

I am not able to call my GPRS shield. It just hangs up. If I type AT then try again, it says the caller is not available at the moment.
I can make a call with it, a can send and receive message. But I can not call it. Why is that?
(Yesterday if I called the shield the monitor printed out “RING”). But now nothing.

#include <SoftwareSerial.h>
 
SoftwareSerial mySerial(7, 8);
 
void setup()
{
  mySerial.begin(19200);               // the GPRS baud rate   
  Serial.begin(19200);                 // the GPRS baud rate   
  delay(500);
}
 
void loop()
{
  if (mySerial.available())
    Serial.write(mySerial.read());
  if (Serial.available())
    mySerial.write(Serial.read());  
 
}

Thanks

OK I solved it by reseting with sending the command “AT&F”
