Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 93

Calls to a particular extension are not routing to voicemail. The user reaches the voicemail system from the handset by pressing the Messages button. Which configuration parameter causes this problem?

Answer options

• A. The voicemail pilot number for call forwarding is missing from the ephone-dn.
• B. The voicemail pilot number is missing from the telephony service configuration on Cisco UCME.
• C. The voicemail pilot number is missing from the call handling on Cisco Unity Express.
• D. The voicemail pilot number for call forwarding is missing from the ephone.

Correct answer: A

Explanation

The correct answer is A because the ephone-dn needs to include the voicemail pilot number for calls to be correctly routed to voicemail. If the voicemail pilot number is missing from the telephony service configuration on Cisco UCME or from the call handling on Cisco Unity Express, it wouldn't directly prevent calls from routing to voicemail but would affect other functionalities. Option D is not correct as it refers to the ephone instead of the ephone-dn.
