I´m trying to make work the SPA232D as a call transfer.
The telephone line works correctly but through a GSM simulator does not work ...
I would like to know what affects the detection of the line. I´ve tried everything and I did not make it work.
I´ve tested with different GSM simulators, with different SIM cards (free PIN code, no answering machine ...). Changing the regional configuration in the SPA232D web interface to Spain, updating the firmware to version 1.4.0 ... and nothing.
I attack a Back Up of the configuration.
