Oh, there is a way to do what you want in 1.4, although it is non-obvious, due
to the insane amount of escaping that needs to be done:
exten => 8122,1,NoOp(${SET(string=one|two|three|four)})
exten => 8122,n,NoOp(${CUT(string,\\|,2)})
-- Executing [EMAIL PROTECTED]:1] NoOp("SIP/vidphone-0824ba08",
"one|two|three|
four") in new stack
-- Executing [EMAIL PROTECTED]:2] NoOp("SIP/vidphone-0824ba08", "two") in
new
stack
Note that this insane escaping has been corrected in 1.6.0.
