300-820 Exam - Question 113

Question

An engineer learns from an end user that calls from outside the company are not being received. Calls are being made to other businesses outside of the company on video using URL addresses. The change management log shows no changes in the configuration of the collaboration solutions. The engineer examines the endpoint, which seems to be registered to the Cisco UCM, and the SIP trunk between the Cisco UCM and sees that the Expressway is also up. In addition, the traversal link shows no errors between the Expressways. Which action must the engineer take to troubleshoot this issue?

Examice · Accepted Answer

The first step in troubleshooting the issue where calls from outside the company are not being received is to determine whether the requests are reaching the Expressway-E. Running diagnostic logging under maintenance on the Expressway-E will help the engineer see if any incoming call requests are being registered by the system. This will help narrow down whether the problem lies with the Expressway-E itself or with an external factor preventing calls from reaching it.

Given the scenario provided, where calls from outside the company are not being received and the initial checks show no apparent issues with the endpoints, SIP trunk, or traversal link, the most appropriate action for the engineer to take to troubleshoot the issue is:

B. On the Expressway-E, run diagnostic logging under maintenance to see if any requests reach the system.

By examining the diagnostic logging on the Expressway-E, the engineer can determine whether incoming calls are reaching the system. This step will help identify if there are any issues with the Expressway-E receiving incoming calls from external sources. It's a crucial next step in the troubleshooting process to pinpoint where the breakdown in communication might be occurring.
