[Imported] Help on AT Commands

This is a re-posting from the obsoleted (October 2018) "Schneider Electric Telemetry & SCADA" forum.


Just wanted to ask about AT commands. Is there a way to get the details about the last call made? like call duration and such. And if the call has ended. The modem does not send out response that the call has ended.


Here's a link to a basic AT command set reference

From that you will not see what you are after. So the answer is no, the standard widely supported AT command set will not give you this.

Now... like with all good standards, no manufacturer follows this precisely, so almost every device manufacturer will have their own proprietary AT commands also.. sometimes these are adopted by more people and they become their own standard of extensions.
Here's a version for GSM

If you advise what particular model of modem you're using, then someone might have more of an idea if that manufacturer has an AT command to access the call list.
