I think passing the variable "on the command line" is more flexible than a 
fixed variable, particularly the much more limiting ${EXTEN}.

My preference is to use the "getopt_long" function to parse the command 
line passed to the AGI. I find

 	exten = _x.,n,agi(dial,--customer-id=112)

to be more "obvious" than

 	exten = _x.,n,agi(dial,${EXTEN})

or

 	exten = 112,n,agi(dial)

This becomes even more obvious when you pass multiple variables:

 	exten = _x.,n,agi(dial\
 		,--announce=winter-specials\
 		,--customer-id=112\
 		,--caller-id=ACME Widgets Inc\
 		,--verbose\
 		,--record\
 		)

(line split for readability)

rather than

 	exten = _x.,n,agi(dial,112,,,winter-specials,ACME Widgets,v,,r)

or

 	exten = 112,n,agi(dial)

Particularly since getopt_long does not care about the order of the 
options.

Thanks in advance,
