This is all going to depend on your gateway or device that turns the DTMF back into tones . /b On Jan 25, 2011, at 12:27 PM, pipiwei03 wrote:

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 ________
