Hi guys,

I have the following in my dialplan:

      <condition field="${<some field>}" expression="<some expression>">
        <action application="answer"/>
        <action application="set" data="api_hangup_hook=curl <some URL>"/>
        <action application="playback" data="tone_stream://v=0;%(1000,0,600)" />
        <action application="conference" data="$1@default"/>
      </condition>

Notice the line in bold.  In most cases the tone plays fine but in some cases it is shorter than 1 second and in a few cases it does not play at all.  Has anyone run into this?  Is there a way to make the occasional media delay after answer go away?
