<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Add HANGUPCAUSE as a drop-in replacement for SIP_CAUSE that does not incur the overhead of the MASTER_CHANNEL dialplan function. This feature uses control frames to pass the data and creates a mechanism by which any channel driver can report cause information. This implementation includes only SIP, but implementations for other channel drivers will be available in the next month.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Verified that this functions identically to SIP_CAUSE in single-channel dials, forked dials, and forked dials behind a local dial.
Sample dialplan:
[foo]
exten => s,1,Dial(SIP/bar)
exten => h,1,noop()
exten => h,n,set(HANGUPCAUSE_STRING=${HASHKEYS(HANGUPCAUSE)})
; start loop
exten => h,n(begin),noop()
; check exit condition (no more array to check)
exten => h,n,gotoif($[${LEN(${HANGUPCAUSE_STRING})} = 0]?exit)
; pull the next item
exten => h,n,set(ARRAY(item)=${HANGUPCAUSE_STRING})
exten => h,n,set(HANGUPCAUSE_STRING=${HANGUPCAUSE_STRING:${LEN(${item})}})
; display the channel ID and cause code
exten => h,n,noop(got channel ID ${item} with pvt cause ${HASH(HANGUPCAUSE,${item})})
; check exit condition (no more array to check)
exten => h,n,gotoif($[${LEN(${HANGUPCAUSE_STRING})} = 0]?exit)
; we still have entries to process, so strip the leading comma
exten => h,n,set(HANGUPCAUSE_STRING=${HANGUPCAUSE_STRING:1})
; go back to the beginning of the loop
exten => h,n,goto(begin)
exten => h,n(exit),noop(All HANGUPCAUSE entries processed)</pre>
