To improve the speed and accuracy of ECHO call handling, and as a joint effort to combat the issue of failed connections due to inaccurate URN data, all NSI approved companies must ensure robust and precise handling of URNs. Technical Bulletin TB 0069 details the requirements which must be complied with to enhance the operational efficiency and uphold the integrity of the NSI certification process. Please ensure your organisation’s adherence to these requirements by the deadline stated in TB 0069.
