Which logging source is commonly used to diagnose signaling problems in CUCM?

• A. SDL/SDI logs
• B. Syslog
• C. SNMP Traps
• D. Event Logs

Answer: (A)

When you're chasing problems with how calls are signaled between endpoints and CUCM, you want the trace that shows the actual signaling messages exchanged during a call setup and teardown. SDL/SDI logs provide detailed records of the signaling conversations (SIP/SCCP/H.323 messages, errors, and the sequence of events). That level of detail lets you see exactly where the signaling path breaks or mismatches occur, such as a missing INVITE, an unexpected response, or a misrouted request. These logs are specifically designed to capture call signaling, making them the go-to source for diagnosing signaling problems in CUCM. Syslog, SNMP traps, and general event logs, while useful for broader system and device health information, do not offer the granular signaling dialogue required to pinpoint issues in call setup and teardown.
