I am unable to press an option when calling to automated phone system. based on research i need to lengthen my DTMF tone to more than 100ms.

mentioned i need to change 80.02.01. The setting at default was 60ms for him and he changed it to 120ms.

However there is no 80-02 option on my nec topaz. not in menu on master phone nor in programming manual.

thanks in advance
 
I believe it is only accessible using programming through the phone and not with the
PCPro program.
