[Asterisk-Users] Matching variables in extensions.conf

[Adam James Dale]

Hi All,

Just wondering, is it possible to set a variable and have it matched as 
below?
I have verified the variable as being set correctly in a previous macro, but 
I doesnt
match when I dial it. :( If  I replace the {$CP} with the number it is 
matched.

exten => ${CP},3,Dial(SIP/${GP}${CP},${RING-TIME})
