Summary:                    [patch] Reason header support
Description: 
Cisco GWs use this header, however it is only a rfc draft.

draft-jesske-sipping-etsi-ngn-reason-03.txt

just set:
use_q850_reason=yes 
in sip peer/user configuration and chan_sip.c will insert
Reason: Q.850;cause=17
header.
If the peer send Reason header will be used instead of
hangup_sip2cause().

This looks good.  There are a few whitespace issues that need to be cleaned
up.  Also I found a potential bug.  In the handle_response() function, if
'cause=' is not included in the reason header, strstr will return NULL, and
asterisk should crash on the call to atoi.  A header in the format "Reason:
Q.850;" should cause a crash.
