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

[Chandramouli P]

Hello David,

We developed a simple audio conferencing application with the help of
FreeSwitch module. Simply, an end user (Host) can call a PSTN number from
their mobile phone and group of people can join in the conference call as
usual. With respect to this scenario, once the call is bridged, the host
can press "0" to mute all other participants in the conference. Here users
or host use regular mobile phone dialer only. In this scenario, host
pressed something on mobile phone dialer instead of "0", and FreeSwitch
received the pressed input by the host as "A". I hope you understand. We
have gone through the log and didn't find any useful hint to know which key
(s) is pressed by the host.

Thank you.

Best regards,
Chandramouli.
