Summary:                    Dialplan variables not set upon blind xfer
Description: 
I'm having a very odd issue where upon executing a blind transfer, the CDR
dialplan variables are not set for the transferred leg of the call.

A calls B (leg is A -> B)
A blind transfers B to C (making the leg now B -> C)

When the B -> C leg of the call ends, the CDR variables in the dialplan,
particularly billsec are unset. This only occurs in the dialplan, the
generated CDRs are fine. This may be related to the h exten code being
moved recently. When I revert to 1.6.0.1, the problem is solved. I can not
compile 1.6.0.2 on my machine, but 1.6.0.3-rc1 is when the problem first
surfaced. For now, I can use 1.6.0.1.

We're playing back a greeting upon reaching a voicemail message. Here is
my dialplan code:

[default]
exten => s,1,Dial(SIP/provider/15555555555,30,T)
; user hits http://bugs.digium.com/view.php?id=1 to transfer to greeting context
so they don't need to wait
for greeting to play back
exten => 1,1,Goto(operator-greeting,s,1)

[operator-greeting]
exten => s,1,Answer
exten => s,n,WaitForSilence(2500,1,25)
exten => s,n,Playback(usermessage)
exten => s,n,Hangup

exten => h,1,NoOp(${CDR(billsec)}) ; is always 0 in 1.6.0.3-rc1 :(.
Correctly defined in 1.6.0.1

Since there are a few ways to do a blind xfer via a sip phone, it can get
pretty important as to which is failing, if not both. Your comment in your
dialplan
code might lead me to believe that the xfer is done via
http://bugs.digium.com/view.php?id=1 (one touch
feature (#)to exten 1)... just need to make sure.
