Yep, returning null would make sense IMHO. But I just ran across this: "Setting a variable to NULL is actually initializing the value to integer '0'. Script variables don't have NULL value.", so if I'd store the result in a script variable I couldn't tell the difference between "sip:saul at ag-projects.com" and "sip:saul at ag-projects.com;gr=0", right? Doh.
