     1 ISN (ITAD Subscriber Number) lookup integration contribution code

     3 Contribution

     5 This contribution introduces ISN formatting logic into the OpenSIPS

     6 ENUM module, allowing it to perform NAPTR based ISN lookups on the

     7 user part of the Request-URI in addition to the existing ENUM lookups.

     9 Rationale

    11 This extends the utility of the existing E.164 formatting logic which

    12 previously caused valid ISN lookups to fail (although the OpenSIPS

    13 documentation did suggest that lookups to freenum.org would succeed.)

    15 Compliance

    17 The author believes that the introduced logic complies with the

    18 relevant ITAD standards as defined by RFC 3872 and RFC 2871, however

    19 it seems that at this time ISN is rather loosely defined according to

    20 nonstandard documentation provided by freenum.org.
