Hello,
I using GSM modem connected with C# application and I am trying to establish program which will control connected GSM modem. I am sending AT commands to the modem and up to now I can read status, network and modem information, send SMS, read all SMS messages... I can call modem and to register incoming call. But the problem is when I am trying to make outgoing call
AT command is very simple:
ATD"Phone_Number";
after that I receive answer:
OK
But phone is not ringing. After about 30 seconds the message is
NO CARRIER
Any suggestion?
