Wasn't "googling" for "asterisk function sprintf" productive?

SPRINTF is not in 1.2

This is obtuse. Unless the guy modifying your dialplan 5 years from now is 
a reasonably advanced C programmer, he will have no clue what you were 
trying to accomplish.

Aside from not handling the null case correctly, your original 2 line code 
was "better." Making your dialplan maintainable is more important than 
potentially shaving a fraction of a millisecond off the execution time.

Thanks in advance,
