Summary:                    [patch] Codec negotiation fails on IAX calls from
1.8.1.1 to 1.8.1.1
Description: 
In the example below, an originating 1.8.1.1 system with the ONLY change in
iax.conf being changing one line from bandwidth=low to bandwidth=high is
not able to connect to a terminating 1.8.1.1 system with the only CODEC
change relevant to a guest user being (a) the change of bandwidth=low to
bandwidth=high and (b) codecpriority=caller inserted.

An originating 1.6.1.6 system with a configuration identical to the
failing originating 1.8.1.1 system is able to connect to the same
terminating 1.8.1.1 system, no problem.

Not so fast.  That's only if it's undef in compat.h, and it won't be
because of things which are included before the #ifndef in compat.h

x.c:
#include "include/asterisk/autoconfig.h"
#include "include/asterisk/compat.h"
main() {printf("Big=%d BYTE_ORDER=%d\n",BIG_ENDIAN,BYTE_ORDER);}
