The IMTC Liaison Statement in IMTC LS2 was a prompted by the SG16 LS in COM16-LS-57; both LSs were also addressed to ITU-T SG11 and JCA-CIT.

We were pleased to be reminded of the important work that the IMTC has been doing to ensure the interoperability of the standards that have been developed by SG16 over the years. It was noted that IMTC maintains not only test suites for various multimedia communication systems, but also "best practice" documents to help implementers to build interoperable products based on existing ITU-T Recommendations and other standards.

The fruitful relationship between IMTC and SG16 has existed for many years as described in details in the IMTC reply LS, and has not been limited to the most recent H.323 standard, which is the one that appears in the reference table of ITU-T Recommendations to be tested for conformity/‌interoperability. Without IMTC’s interoperability testing events and well developed test plans, full interoperability of several ITU-T Recommendations developed by SG16 would still be exposed to bugs and interpretation-related implementation deficiencies.

We would like to re-affirm our commitment to interoperability and the long-time, very valuable relationship with IMTC, whose cooperation over the years has been essential for SG16 meeting its objective of a high level of interoperability for the Recommendations under its responsibility.
