Hello. In my IVR, It recognized double DTMF values. I need to keep only one DTMF value. ( I mean, If user press 1 and 3 in same time, My asterisk recognize it as 13. But I need to get only one value, If user press 1 and 3 in same time, I need to get only 1st presses number.) How do it
You would need to show the dialplan and console output, to show exactly what you are doing and how you are using Asterisk.
As far as anything at the other end of the line from the phone is concerned, those are two consecutive key presses. If you are using WaitExten or Background, you are going to have to train your users better. If you are using Read, you will need to limit the number of digits you process.
Note that it is likely that the phone scans the key board, so if certain combinations of keys are pressed sufficiently close together, they may be read in a different order, than pressed, by the phone. This means that even if you could disable key rollover on the phone, it might still produce unexpected results. Key rollover is to the ability to press a sequence of keys with down times for the keys overlapping, and still have them interpreted as a sequence. (Keyboards without rollover support are rare, and tend to return a completely wrong key-press when this happens. Standard computer keyboards have rollover.)

Lot doesn’t match dialplan. However, it doesn’t change my original response, that you really need to fix this at the phone.
