Variable as prefix - extensions.conf

Hi,

it’s possible to use in extensions.conf a variable as prefix?

Example:

exten=> ${RCID_TEST1}200,1,…

Where I have to set RCID_TEST1? If I set RCID_TEST1 in [globals], I don’t see anything in CLI:

[ Context ‘TEST1’ created by ‘pbx_config’ ]
(nothing)

Thanks!
