Hello. I am sending outbound dtmf over g729 using rfc2833. Generally it works perfectly. The only issue is that, when 2 subsequent digits are the same, the receiver detects them as a single digit. For instance, if I send 1234, it is detected as expected as 1234. However, if I change that to 2234, it is detected as 234.<div>
<br></div><div>I have played with rtp-digit-delay and dtmf-duration extensively to no avail. I&#39;ve also tried both queue_dtmf and execute_on_answer=send_dtmf. Anyone have any ideas? Any help much appreciated. Here is the extension that I&#39;m using in my dialplan:</div>
<div><br></div><div><div>  &lt;extension name=&quot;test_conference&quot;&gt;</div><div>    &lt;condition field=&quot;destination_number&quot; expression=&quot;^test_conference$&quot;&gt;</div><div>      &lt;action application=&quot;playback&quot; data=&quot;wait.wav&quot; /&gt;</div>
<div><div>      &lt;action application=&quot;set&quot; data=&quot;effective_caller_id_number=5555555555&quot;/&gt;</div></div><div>      &lt;action application=&quot;export&quot; data=&quot;nolocal:absolute_codec_string=G729&quot;/&gt;</div>
<div>      &lt;action application=&quot;flush_dtmf&quot;/&gt;</div><div>      &lt;action application=&quot;queue_dtmf&quot; data=&quot;2234&quot;/&gt;</div><div>      &lt;!-- &lt;action application=&quot;export&quot; data=&quot;nolocal:execute_on_answer=send_dtmf 2234&quot; /&gt;--&gt;</div>
<div>      &lt;action application=&quot;bridge&quot; data=&quot;sofia/internal/${bridge_number}@${trunk_ip}&quot; /&gt;</div><div>      &lt;action application=&quot;hangup&quot; /&gt;</div><div>    &lt;/condition&gt;</div>
<div>  &lt;/extension&gt;</div></div><div><br></div><div>Thanks,</div><div>Mark</div>
