Is it possible to make an outgoing call with the "ATD" command with the firmware version RUT9XX_R_00.06.08.6?
I think that in this version of the software it is not possible to make calls by AT commands, only some basic AT commands are allowed. Can someone tell me for sure?
I have tested it by updating to firmware RUT9_R_00.07.01.4 and it works. But this version gives other problems and I need to go back to the previous firmware.
