I am looking for help on a case where the ATA is actually hearing duplicated tones from the
connected analog phone.
The analog phone connected to the PAP2T dials 12345 but the PAP2T is then calling 1122334455...
What can be causing the ATA to hear duplicated tones and how can that be workarounded?
I tried increasing the FXS input gain but this did not solved the issue....
