Lebogang Masenya commented on ASTERISK-19711:
---------------------------------------------

I have Recently encountered a similar issue on my asterisk 1.8.25.0. 

We had to do some experimentation with some of the calls being seen as Spiraling calls of which the issue was resoled by setting padentic=yes, in sip.conf.

I see a similar error

"Found duplicate exten. Had %s found %s\n" on one of the extensions trying to register, and Asterisk keep segfaulting

Currently the only solution is to revert to setting "padentic=no" and the crashes stop immediately.

Please find attached a couple of backtraces that were produced form the crashes.

> Reproducaebility is pretty random but it does happen often when doing lots of:
> dialplan add extension xxx   from the console
> The crash will get triggered especially when the extension already exists.
