# telephoneNumberMatch

Compares an assertion value of Telephone Number syntax to a value whose syntax is an ASN.1 PrintableString representing a telephone number.

The rule evaluates to TRUE if and only if the assertion value and the attribute value are of the same length, and corresponding octets are the same. For the comparison, characters are case folded, and only telephoneNumber insignificant white space handling is applied.
