[Freeswitch-users] problem with "play_and_get_digits" command (DTMF delay time)

[Manish Talwar]

Hi,


I have found one small problem with "play_and_get_digits" command. We have a IVR application and I am trying to get  either "16 digit" card number or "0" for move to customer support from the user.  Please find my dialplan as follows:

It is working fine as expected if user input 16 digit number continuously without any delay.  After getting full 16 digit number it will match the "bind_digit_action" and move to other dialplan.


But my problem is if a user enter card number slowly then its trying to match already inputed DTMF values with matching binding and received next inputed value as different DTMF values. As a example, if I tried to input 55 and then wait for 1-2 seconds then Freeswitch tried to match 55 with binding.

I don't want fresswtich tried to match the binding if there is any pause time while inputed the number as user can type slowly.


I want to reset this binding delay time so that user can type slowly and we will get full 16 digits number for matching inputed value in certain time interval.


Please suggest me how can I resolve this problem and increase the DTMF delay time.


Thanks,


Regards,
