[Freeswitch-users] DTMF recognition and nbound calls

I had the same problem #2 using an analog line and a Xorcom astribank.  I also found that the analog line inbound caller could hangup before any internal analog extensions had answered, and FS wouldn't see the hangup properly and keep ringing the internal analog extensions.

I ran out of fiddling time, so never resolved this but would really like to see it working.

  For problem #1 you probably need to use the DTMF detection application. The symptoms your describing match and your code is missing this.

  Try adding:
  <action application="start_dtmf" data="true"/>

  Problem #2, does this occur on an analog line?

  Dear All,


  I have setup my inbound extension (in the public.xml) diaplan to transfer to extension 5000 à the demo IVR

  The recordings come through nicely. From an internal call the demo fine including DTMF recognition but with inbound calls from external source.ie pstn line



  Two problems occur.

  1.       There is no DTMF recognition

  2.       If I hangup during the playback the system still plays out the whole IVR


  Here is my code for the extension.


  Hopefully someone can help me out

  <extension name="public_did">

        <condition field="destination_number" expression="^(0283472006)$">

              <action application="set" data="call_timeout=60"/>

              <action application="set" data="group_confirm_file=C:/Program Files/FreeSWITCH/sounds/en/us/callie/voicemail/8000/vm-press.wav"/>

              <action application="set" data="group_confirm_key=4"/>


      <action application="set" data="RECORD_TITLE=Recording ${destination_number} ${caller_id_number} ${strftime(%Y-%m-%d %H:%M)}"/>

      <action application="set" data="RECORD_COPYRIGHT=(c) 2008 Diagnostic Devices, Inc."/>

      <action application="set" data="RECORD_SOFTWARE=FreeSwitch"/>

      <action application="set" data="RECORD_ARTIST=Ian Curtis"/>

      <action application="set" data="RECORD_COMMENT=Love will tear us apart"/>

      <action application="set" data="RECORD_DATE=${strftime(%Y-%m-%d %H:%M)}"/>

      <action application="set" data="RECORD_STEREO=false"/>

       <action application="set" data="playback_terminators=#*"/>

      <action application="record_session" data="C:/Program Files/FreeSWITCH/recordings/${strftime(%Y-%m-%d-%H-%M-%S)}_${destination_number}_${caller_id_number}.wav"/>

      <action application="set" data="ringback=${us-ring}"/>


   <action application="transfer" data="5000 XML default"/> 


           <!--    <action application="bridge" data="user/1207@$${domain}"/> -->
