<div>The call props up and then things just go wrong. I have talked with the support guys at NetGen and they have requested I work start with the asterisk dev group so we can figure out what is causing this issue and why asterisk is dumping. They are willing to fix anything from their end but we have not been able to figure out what in their rtp stream is triggering this. Their ATA's seem to work out side of the confbridge without issues so far. Any ideas are appreciated. The asterisk dump is by far my biggest concern. </div>

<div>Below is the first part of the dump Backtrack. I have attached a copy of the complete Backtrack. I need to know what more would be needed to get to the bottom of this issue. As it stands now the NetGen Smart ATA will cause asterisk 13 to crash if placed into a confbridge. <a href="http://www.netgencommunications.com/" target="_blank">http://www.<wbr>netgencommunications.com/</a></div>
