A first it seemed like the variable was set until Answer() was called but it 
is not the case. More testing revealed the vars gets cleared when Asterisk 
bridges the channel and chosen extension set in the call spool file.

A matching segment of the dialplan:

exten => s, 2,NoOp(id = ${id})
exten => s, 3,Answer()
exten => s, 4,NoOp(id = ${id})
exten => s, 5,Wait(1)
exten => s, 6,NoOp(id = ${id})
