<p class="MsoNormal">A is a valid DTMF digit so I wouldn’t worry about it too much and just handle A-D in your valid TT fields. I see around a million calls a day and see a few hundred A-D DTMF. It’s rare, but some really old phones still have the A-D DTMF
on them, and softphones have the ability to send them as well, maybe your user is using a softphone on their end?<u></u><u></u></p>

<p class="MsoNormal">We developed an application (FreeSwitch) that receives pressed digit by the end user on mobile phone dialer through DTMF and some action will be performed. Everything is working fine till now. But, we noticed one issue recently. From the
FreeSwitch log, we came to know that FreeSwitch is received the letter i.e. "A" from DTMF, instead of digit. We tried to regenerate this issue. But, when we are trying to regenerate, FreeSwitch is receiving the digit from DTMF as usual. I would like to know
How FreeSwitch is received the letter i.e. "A", instead of digit. Which key was pressed by the end user on mobile phone dialer?<u></u><u></u></p>
