Dear all:

I try to send DTMF tone. 

 I use two method in lua 

1.queue_dtm after bridge 

2. send_dtmf in a session

these two methods are working and call my phone successfully

But, I got a problem is...

After bridge, I hear soon DTMF tones. 

The heard DTMF tones are so short. It is very strange to feel as broken.

Even though I set and increase the tone_duration as below:

      queue_dtmf "12345678@5000" 

  or send_dtmf "12345678@5000"

The heard DTMF tones also very short, but the duration between inter-digit become longer...

Somebody tell me how to make "heard DTMF tone" longer...or silent the dial tone and sent DTMF tones.

Thanks a lot for your support.

Best regards,

Joy
