1.4 +ISN (ITAD Subscriber Number) lookup integration contribution code
1.5 +
1.6 +Contribution
1.7 +
1.8 +This contribution introduces ISN formatting logic into the OpenSIPS
1.9 +ENUM module, allowing it to perform NAPTR based ISN lookups on the
1.10 +user part of the Request-URI in addition to the existing ENUM lookups.
1.11 +
1.12 +Rationale
1.13 +
1.14 +This extends the utility of the existing E.164 formatting logic which
1.15 +previously caused valid ISN lookups to fail (although the OpenSIPS
1.16 +documentation did suggest that lookups to freenum.org would succeed.)
1.17 +
1.18 +Compliance
1.19 +
1.20 +The author believes that the introduced logic complies with the
1.21 +relevant ITAD standards as defined by RFC 3872 and RFC 2871, however
1.22 +it seems that at this time ISN is rather loosely defined according to
1.23 +nonstandard documentation provided by freenum.org.
