I would advise to check the $ci string to avoid some kind of injection of code because you don't know who generates this callerid field and I have found some external carriers and untrusted clients that using quotes, curly brakes, colon and semicolons inside of the callerid values.

Use $(ci).wav to explicitly mark the name of the variable -- the . is allowed in the variable name and the interpreter goes ahead to identify the longes possible variable name.
