How to read user input during sound file playing?

I used Background() and it work fine , i did two extensions as bellow :

exten => 1,1,Playback(${Sound_Path})

exten => 2,1,Playback(${Sound_Path2})

But when i pressed (1) or (2) , i need more than one press to go to the exten No. 1 or No. 2???

what the problem ?

Echo of the outgoing audio is jamming the DTMF tone. It is normal to silence any outgoing audio after the first digit.

Note that the UK had to change its dial tone when it introduced DTMF, as the original dialtone was rich in harmonics and particularly effective at jamming DTMF.

That’s mean some user inputs are ignored :question:

Thank you for your reply :smile:
