Hi, i am facing a problem after upgrading the ICM version 7.1(4) to 7.2.2, while call landing to the agent, frequently an invalid CallID '-1' is showing at CTI Toolkit, while CallType is showing 'INVALID'. Afterwhile a CTI Warning popup is showing 'The connection identifier is not valid'. FYI, i didn't upgrade the CTI Toolkit, it's still at version 7.0, as cisco says it's fully compatible with CTIOS 7.2. What's the cause of the problem? How can I resolve the issue?
I have this problem too.
