[Freeswitch-users] DTMF Issue - Unexpected digits are receiving

[Chandramouli P]

Hello,

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?

Thank you.

Best Regards,
Chandramouli.
