Description: | The extensions_additional.conf file (sent via email, as it contains confidential information) causes asterisk to crash when read.
There are syntax errors in it (matches don't start with _, starting at line 6861), and when they were fixed, asterisk stopped crashing. However, when they were removed AGAIN, asterisk STILL wasn't crashing. At this point we managed to dig up a COPY of the exact file that was causing the crash, and confirmed that it crashes on another machine. | ||

If not at startup, do a "dialplan reload" a few times. The missing leading '_' in the pattern, the length of the pattern, and the length of the label are all factors.
