<p class="MsoNormal">I've got an issue where when I call a number that just plays early media back to me.<o:p></o:p></p>

<div>
<p class="MsoNormal">Instead of hearing the full sequence of tones I hear a short ringing then part of the sequence. What seems odd is that I can see the telephone-event/8000 being passed up the chain but when it gets to Asterisk, it is never sent back to the
phone. Instead I just see the usual RTP flows.<o:p></o:p></p>
