Question
An engineer is supporting an existing Cisco Collaboration deployment that has internal and external home users using the solution without VPN. Business usage also includes B2B calling for voice and video. Suddenly the engineer receives a report that one of the home office users cannot use the Cisco Jabber client, and shortly after, a few more reports come in for the same error. What must the engineer check first to resolve this issue?
Options
- Aclient logs of the users
- Breal-time monitoring toll logs for problems
- Calarms on the Cisco Expressways
- Dalarms on the Cisco UCM Cluster

Explanation
When multiple remote/home users simultaneously lose access to Cisco Jabber without VPN, the common infrastructure component they all share is the Cisco Expressway pair. Checking alarms on the Expressways first is the most efficient approach because a single Expressway issue (e.g., certificate expiry, capacity limit, connectivity failure) can affect all MRA users at once. Client logs are useful for individual user issues, not widespread outages. RTMT logs on CUCM are a secondary check. UCM cluster alarms are less likely to be the cause since internal communications are reported as working, which isolates the problem to the external access layer handled by the Expressways.
