Summary:                    Call from '' to extension '7104' rejected because
extension not found
Description: 
I've had a few of these errors:

[Feb  8 16:35:33] NOTICE[2170]: chan_sip.c:13879 handle_request_invite:
Call from '' to extension '202' rejected because extension not found.
[Feb  8 16:35:49] NOTICE[2170]: chan_sip.c:13879 handle_request_invite:
Call from '' to extension '7104' rejected because extension not found.

And shortly there after, it crashes. I'll enclose my crash report with
DONT_OPTIMIZE. The dead thread is http://bugs.digium.com/view.php?id=11
-1246659664 LWP 18653

Thread 11 (process 18653):
0  0xffffe410 in __kernel_vsyscall ()
No symbol table info available.
1  0xb7fc556e in __lll_mutex_lock_wait () from

I've traced all of the channels that were in the main channels list, and
all of them seemed normal. One (http://bugs.digium.com/view.php?id=1) was making
an outgoing call, and
waiting on the lock that thread 11 had before it crashed.

My boss dialed 202 and he noted that it died right after that. Is this
really the cause of the crash? If so, what's going on? I do have a dial
plan rule for _2XX and 7104, so it appears to have lost it's context.

I guess I answered my own question. This patch does not fix all of the
problems:
