[Freeswitch-users] How to make the heard DTMF tone more longer

[pipiwei03]

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 at 5000"
  or send_dtmf "12345678 at 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
