    One of my users is complaning about communicator freezing, when ending quite long (~30 min) calls. The problem can be reproduced, but only his machine/client is behaving this way. Applyed the recent 2008.04 update, but issue still present.

    I am not sure how to troubleshoot the problem, as communicator UCCP logs may be corrupt, or not include the events that directly caused the problem.
