CTP Manager and Summer time problem


We have problems with our CTP Manager running under version (587).

Every Weeks Meetings which are created before the Summertime change in march,

are now starting one hour to late.

The Time on all Servers and endpoints is correct.

The meetings are booked over outlook.

The time for the reservation in outlook is correct.

The time which is displayed on the Phone (CTS1300) for the meeting

is on hour to late !

Any new created meeting is working correct.

Any ideas ?

Best  Regards

CTP Manager and Summer time problem

Hi Thomas,

Did you upgrade the CTS Manager recently, and if so what version did you upgrade from?

This issue used to be fairly common with systems running versions prior to 1.7.2 (see CSCtj95619 for more details), and indicates that the CTS Manager is unable to find a timezone mapping between what is returned from the calendar server and what is in the local CTS Manager database. If CTS Manager is unable to resolve this mapping, then it resorts to scheduling the meeting without any DST offsets.

If your system was running a version prior to 1.7.2, and the affected meetings were booked prior to the upgrade, then the only workaround is to reaccept the meeting in outlook or OWA.

If the system was not running a version prior to 1.7.2, then can you please look in the CTS Manager GUI and click on Troubleshoot > System Messages, and search for any messages with the text "Unresolved timezone mapping" and copy the exact message?

Thank you,
