It works for me (using CVS HEAD, but I'm sure it's worked in the past for
me on Stable too). I think there must be some other reason it's not working
for you.

Just done a little test for it, as follows...

My extensions.conf:

[vartest]
exten => _X.,1,SetVar(FRED=hello)
exten => _X.,2,NoOp(FRED=${FRED})
exten => _X.,3,Playback(demo-congrats)
exten => _X.,4,Hangup

exten => h,1,NoOp(FRED=${FRED})

Console output:

    -- Executing Goto("SIP/2002-238e", "vartest|8200|1") in new stack
    -- Goto (vartest,8200,1)
    -- Executing SetVar("SIP/2002-238e", "FRED=hello") in new stack
    -- Executing NoOp("SIP/2002-238e", "FRED=hello") in new stack
    -- Executing Playback("SIP/2002-238e", "demo-congrats") in new stack
    -- Playing 'demo-congrats' (language 'en')
  == Spawn extension (vartest, 8200, 3) exited non-zero on 'SIP/2002-238e'
    -- Executing NoOp("SIP/2002-238e", "FRED=hello") in new stack

    -- Executing Goto("SIP/2002-9d08", "vartest|8200|1") in new stack
    -- Goto (vartest,8200,1)
    -- Executing SetVar("SIP/2002-9d08", "FRED=hello") in new stack
    -- Executing NoOp("SIP/2002-9d08", "FRED=hello") in new stack
    -- Executing Playback("SIP/2002-9d08", "demo-congrats") in new stack
    -- Playing 'demo-congrats' (language 'en')
    -- Executing Hangup("SIP/2002-9d08", "") in new stack
  == Spawn extension (vartest, 8200, 4) exited non-zero on 'SIP/2002-9d08'
    -- Executing NoOp("SIP/2002-9d08", "FRED=hello") in new stack

On the first call, I hung up during the announcement. On the second,
I let the system hang up on me. The h extension showed the variable
value in both cases.
