DTMF Issue - Unexpected digits are receiving
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.
From what i know, "A" is a multifrequency tone, 697hz+1633hz. Maybe the client is actually sending that.

Hello David, Thanks for your reply and I understand. But, As I explained, we tried to regenerate the issue by pressing different keys on dial pad. But, FreeSwitch is receiving the digits as usual every time. So, which key was pressed by the user on dial pad to send "A"? Any assumptions? Thank you. Best regards, Chandramouli.

I guess that depends where the dtmf is coming from, is it your client? Is the client actually capable of sending that? You need traces. On Mon, Oct 22, 2018, 09:43 Chandramouli P <mouli123@gmail.com> wrote:

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. *Please find the here: *https://pastebin.com/3NBU1xyu Thank you. Best regards, Chandramouli.

Hi, I encountered the same issue in the past and have noticed that it was the mobile voicemail beep tone that was sometimes converted to 'A' dtmf on the isdn gateway. Maybe your case is similar? Best Regards, -- Vallimamod Abdullah SIP Solutions vma@sip.solutions linkedin.com/in/vallimamod .

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?

Hi Chandramouli, This is DTMF association to symbols: 569 * 570 * Tones: 571 * 1209 Hz | 1336 Hz | 1477 Hz | 1633 Hz 572 * 697 Hz '1' '2' '3' 'A' 573 * 770 Hz '4' '5' '6' 'B' 574 * 852 Hz '7' '8' '9' 'C' 575 * 941 Hz '*' '0' '#' 'D' If the device has different keypad from above then you need to find out which key it has mapped to DTMF comprised from 697 Hz/1633 Hz frequencies. cheers, Piotr
Hello Piotr, Thanks for your reply. But, my issue is how to regenerate this issue? That is the main problem as I explained. Thank you.

Hello Branden,
Thank you for your reply. As you said, I do understand about A-D DTMF digits. But, my problem is to regenerate the issue i.e. ("A"). Which key (s), I have to press to send "A" as DTMF digit? I am sure that the end user is used regular mobile phone dialer only, and not softphone.
Thank you.
Best Regards, Chandramouli.

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?

Hello Abdullah,
Thank you for your reply. By following your hint, I tried to regenerate the issue. I tried by getting voice mail beep, other beeps like receiving SMS, WhatsApp messages etc. But, unable to simulate.
Thank you.
Best regards,

Hi,
I encountered the same issue in the past and have noticed that it was the mobile voicemail beep tone that was sometimes converted to 'A' dtmf on the isdn gateway.
Maybe your case is similar?

Hello David,
Thanks for your reply and I understand. But, As I explained, we tried to regenerate the issue by pressing different keys on dial pad. But, FreeSwitch is receiving the digits as usual every time. So, which key was pressed by the user on dial pad to send "A"? Any assumptions?
Thank you.
Best regards,
Chandramouli.

From what i know, "A" is a multifrequency tone, 697hz+1633hz. Maybe the client is actually sending that.

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.
