Re: Global variables in global variables

I believe that EVAL might be able to help you here:
https://wiki.asterisk.org/wiki/display/AST/Asterisk+16+Function_EVAL

Example:

        Allphones=${EVAL(Kphones)}&${EVAL(Sphones)}

I'm not sure if in the globals it will let you, but in the dialplan for
sure it will.
