Oggetto: Re: [Freeswitch-dev] FreeSWITCH Core Dump

I added some protection in the core that will keep this from happening,
but there is something definitely not right here.  I assume this is only
on a call that has no match in the dialplan, correct?  Can you post a
FreeSWITCH(tm) debug trace of this call as well?
