Explanation

CallManager traces (also called Cisco CallManager SDL traces) are the primary source for call routing and digit analysis information in Cisco Unified CM. They capture the full call setup flow including partition and Calling Search Space (CSS) evaluation, route pattern matching, route group/list selection, and gateway selection logic. When a call fails or is misrouted due to a CSS issue, the CallManager trace will show exactly which partitions were searched, what patterns were compared, and why a route was selected or rejected. CTI Manager traces are for Computer Telephony Integration applications, and Cisco IP Manager Assistant traces are for the assistant/manager feature-neither is relevant to CSS-based routing failures.
