Cisco Troubleshooting Cisco Unified Communications v8.0 (TVOICE v8.0) Sample Questions:
Refer to the exhibit. You have received a trouble ticket stating that calls to local PSTN numbers are failing. To place a call, Cisco Unified CallManager users dial the access code "9," followed by seven digits. After entering the debug voice dialpeer command on the H.323 gateway, you have the user attempt the call again.
Based on the debug output, what is the most likely cause of this problem?
- A. Cisco Unified CallManager is stripping the access code, resulting in only seven digits being sent to the gateway.
- B. The call is not matching an inbound dial peer resulting in a codec mismatch.
- C. There is a physical layer issue with the circuit.
- D. The gateway dial peer needs to prefix the access code to the called number.
You have received a trouble ticket stating that the MWI light is not coming on for a group of users. Further investigation reveals that the affected users are connected to the same subscriber in the cluster. Users that are connected to other subscribers in the same cluster are not experiencing this issue.
What is causing this problem?
- A. The MWI numbers for this subscriber have been changed.
- B. Database replication has an error or has failed.
- C. The Cisco Unity voice-mail services need to be restarted for the subscriber so all the users will receive proper MWI message indication.
- D. The voice-mail ports assigned to the subscriber are down.
Refer to the exhibit. A site is using four-digit extensions for internal calling. The voice-mail pilot number is 8000. Calls to extension 2001 hear the Cisco Unity opening greeting instead of the subscriber's greeting when forwarded to Cisco Unity.
What is the probable cause?
- A. Extension 2001 has not been defined in Cisco Unity.
- B. A call routing rule has been added that is preempting the Attempt Forward rule.
- C. A greeting has not been recorded for mailbox 2001.
- D. The mailbox is configured with the E.164 number instead of the extension.
- E. The Voice Mail Box Mask setting in Cisco Unified CallManager is set to 8000 instead of XXXX
Which step in the problem-solving model is important to accurately interview end users to get all the pertinent details of the problem?
- A. Consider the Possibilities
- B. Gather Facts
- C. Define the Problem
- D. Restart Problem-Solving Process
- E. Problem Resolved
- F. Implement Action Plan
- G. Observe Results
- H. Create Action Plan
