Summary:                    [patch] New option setvarout which sets channel
variable for outbound channels to a peer
Description: 
The setvar option in sip.conf sets channel variables for inbound channels
(calls from a peer to *), but not for outbound channels (calls to a peer).
This patch adds support for a new option "setvarout" which adds that
capability.

Usecase:
The automon feature writes the recording to a file which contains the
channel name. It is currently not possible to reliably parse the name of
the peer from the channel. Setting the channel variable
TOUCH_MONITOR_PREFIX before executing the Dial(...,10,wW) app does not
work, because you cannot discriminate whether the caller or the callee hit
the record button. Using setvarout it is possible to have a easily parsable
automon file, by setting the TOUCH_MONITOR_PREFIX to the name of the peer
for inbound and outbound channels.

OK, so here is a suggestion from Russell that I think might work.

Use the M() flag to Dial() to set two different values as that will be
executed on the called channel and not the calling channel. Perhaps
something like this:



exten => _X.,1,Set(TOUCH_MONITOR_PREFIX=caller)
exten => _X.,n,Dial(SIP/callee,,M(setMonitorPrefixCallee^callee)

[macro-setMonitorPrefixCallee]
exten => s,1,Set(TOUCH_MONITOR_PREFIX=${ARG1})




Does that work?
