Summary:                    SIP hairpin invokes Local within app_dial to produce
a crash.
Description: 
We are getting crashes in app_voicemail on a fairly regular basis.  I'm
still working on steps to re-produce, but I thought I would post the
backtraces here in case someone could glean anything from them.  I will
update if I can figure out the steps to re-produce.

Corydon76, qwell-

I have another example / bt of the last reported crash that points to
chan_sip.  Should I open this in a totally separate bug instead of this
one?  I realize that this may not be directly related to the original issue
reported here, and that these updates may be misplaced.  Let me know if I
should open a separate bug and I am happy to do so.  Just as before, this
again happened during an inbound call to a large ring group with 25-30 sip
peers being dialed simultaneously.

This is 1.4.11.

Here are the last messages:

I'm uploading the bt as well.
