Read Mark-Jason Dominus's rants against doing this in Why it's stupid to `use a variable as a variable name'.

You would limit the scope of your changes to $phone by starting the block with

local $phone;

or even

local $$vname;

(Though either changes $phone for any subs called from your block too, so it's not the same as the lexical scope of a my() declaration.)
