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'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'm using in my dialplan:</div>
<div><br></div><div><div> <extension name="test_conference"></div><div> <condition field="destination_number" expression="^test_conference$"></div><div> <action application="playback" data="wait.wav" /></div>
<div><div> <action application="set" data="effective_caller_id_number=5555555555"/></div></div><div> <action application="export" data="nolocal:absolute_codec_string=G729"/></div>
<div> <action application="flush_dtmf"/></div><div> <action application="queue_dtmf" data="2234"/></div><div> <!-- <action application="export" data="nolocal:execute_on_answer=send_dtmf 2234" />--></div>
<div> <action application="bridge" data="sofia/internal/${bridge_number}@${trunk_ip}" /></div><div> <action application="hangup" /></div><div> </condition></div>
<div> </extension></div></div><div><br></div><div>Thanks,</div><div>Mark</div>
