[Freeswitch-users] queue_dtmf and send_dtmf merging digits

[Mark Dillon]

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.

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:

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

Thanks,
Mark
