<div>Thank you we will get 13.18.4 on the test box ASAP, and thank you for the wiki link so we can pull together additional information to resolve this issue.

<div><span style="font-family:Arial,Helvetica,sans-serif;font-size:12px">We are having an issue with asterisk 13.17.1 dumping when a call from a NetGen Smart ATA drops into a confbridge</span></div>
<div><span style="font-family:Arial,Helvetica,sans-serif;font-size:12px">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. </span></div>

<div>There's not a whole lot of info in this backtrace for us to really know what's going on but can you try with 13.18.4? There have been recent crash fixes that may help.</div>
<div> </div>
<div>If 13.18.4 doesn't help, recompiling with debugging turned on, re-creating the issue, then following the wiki instructions to get a backtrace will help us figure out what's up.</div>
