How to know whether a call is made or not using AT Command terminal output

Question

I am using SIM908 (it includes a GPS and GSM modem in one module) to call someone. I issued the ATD command along with the phone number to call. Sometimes it will call, and in sometimes it wont.

I will get a "NO CARRIER" reply when the other end cuts the call after conversation or the device is not reachable/switched off.

I will get "BUSY" reply when the other end cuts the call while ringing.

My problem is, I want to distinguish whether the call is actually made or not. Since I am getting "NO CARRIER" for both, I can't use that as an indicator.

Anybody have an efficient way to detect whether the call is actually made or not.

Thanks in advance...

In my experience with AT, there's no way to do that 'in runtime'. But you can check the 'response' RING from the console.
