Richard Mudgett commented on ASTERISK-27094:
--------------------------------------------

The backtraces in the new file [^core-asterisk-running-2018-05-16T10-28-36-0400.rar] still don't have any useful symbolic information.  You can tell if you actually look at the core-asterisk-running-2018-05-16T10-28-36-0400-thread1.txt or core-asterisk-running-2018-05-16T10-28-36-0400-full.txt file as you will see "No symbol table info available." all over those files.  The output of the CLI "core show locks" command is also missing useful symbol information.  It is only giving public function names and hex offsets.  To be useful the output needs to give function names and line numbers.

It appears that you are *selectively* installing files with debugging information.  A few loadable modules like app_dial and chan_sip have debugging information but the asterisk executable does not have debugging information.  I stated nearly a year ago that this is *not* a channel driver (i.e., chan_sip) specific deadlock and that it is in the bridging core code.  The bridging core code is in the asterisk executable itself.

FYI: The {{.rar}} archive format is *very* inconvenient to deal with.  I not only have to explicitly download the file but I had to locate a utility that understood the format.  {{.zip}} would be much better as JIRA knows about that format and I don't have to download the file to look at it.

> All calling via SIP PSTN carrier.
> progressinband = yes
> directmedia =  yes
> prematuremedia  =  no
> Incoming call A is answered with progress
> Then bridged with progress to external call B
> Call is processed with audio OK
> But no further SIP processing in console and all SIP further signalling dies including OPTIONS packets.
