    One thing I kept questioning is whether to use ast_str for these functions or to just use char *. I decided to use ast_str because, especially for the conversion to string, the size of the UUID does not need to be known and the string can expand as necessary.

However, when I downloaded the source for the library on my machine, the code had the 3-clause BSD license printed in the source. In either case, I believe use of external library is license-compatible with Asterisk.
