asterisk users - Jun 2005 - Set global variables without extension..

Is it at all possible to set a Global Variable freely whenever a context gets
used without having to enter an extension priority to use SetGlobalVar?  This is
really limiting the dialplan for me.  Heres an example of what I would like to
be able to do.


[globals]
AREACODE
[local]
exten=_NXXXXXX,1,Dial(SIP/${AREACODE}${EXTEN}/blah)

[anyoldcontext1]
AREACODE=313
include=local

[anyoldcontext2]
AREACODE=810
include=local


so then sip accounts would point towards either anyoldcontext1 or anyoldcontext2
and depending on what is set in sip.conf for a context depends on what their
area code the sip account would use.  Anyone have any ideas?  I suppose my last
resort will be to modify the source but an simple alternative would be nice. 
Thanks a lot

[anyoldcontext]
exten => _X.,1,Set(AREACODE=313)
include => local

[anyoldcontext2]
exten => _X.,1,Set(AREACODE=810)
include => local

[local]
exten => _XXXXX,2,Dial(${AREACODE}...)

This will do exactly what you want, except if you try to send a call to 
this context that should not match anything in 'local' (since it will 
match the _X. pattern).
