Abstract: / This liaison statement provides additional background information which is related to the implementation of ITRs following the outcomes of discussion at the ITU-T SG11 meeting (8-17 November 2017).

ITU-T Study Group 11 would like to thank TSAG for the incoming Liaison Statement (TSAG-LS 8).

The ITU-T SG11 Chairman has already informed TSAG in September 2017 (SG11-LS20). After further discussion at the ITU-T SG11 meeting (8-17 November 2017), concerning the relevant ITUT Recommendations and the role of SG11 in implementing the 2012 ITRs, the SG11 meeting agreed the following:

SG11 is a technical study group and at this time, SG11 has not perceived any impact the 2012 ITRs have on ITU-T Recommendations, developed and approved by SG11;

SG11 recognizes that there are a series of ITU-T Recommendations developed by SG11 that are related to the provision of International Calling Line Identification (mentioned in article 3.6 of 2012 ITRs), including:

ITU-T Q.731 series: The Recommendation defines signalling requirements to supplementary services such as CLIP, CLIR, COLP and COLR;

Q.3617-Q.3639: Service and session control protocols – supplementary services based on SIP-IMS.

This information will be reflected in the report of SG11 for the TSB Director’s consideration.
