* 3.2 Supplementary Information String Identifier
* The identifier comprises one or more IA5 numerals 0-9 which may
* be followed by a single IA5 alpha-character suffix in the range A-Z.
* The numerals of the identifier indicate the main function of the
* Supplementary Information String, eg "39F" indicates "Diverting

* The Destination Address comprises one or more IA5 numerals 0 to
