I will use it to check if a Caller has already a open connection to a
specific destination.

In that moment I use e.g. Set(active_${CALLERIDNUM}=1|g) to set a global
variable in my dialplan. After the caller hung up I will use
Set(active_${CALLERIDNUM}=|g) to remove my global variable
"active_${CALLERIDNUM}".

Is the Memory space of variable really free? Or will I rise into a 
memory problem if I do so?
