350-801 Question #184: Real Exam Question with Answer & Explanation

Question

An end user at a remote site is trying to initiate an Ad Hoc conference call to an end user at the main site. The conference receives an error message on the phone: Cannot complete conference call. What is the cause of the issue?

Options

• AThe transcoder resource Is missing.
• BThe remote phone does not have the conference feature assigned
• CA software conference bridge is not assigned.
• DA Media Termination Point is missing.

Explanation

The conference call failure with 'Cannot complete conference call' suggests that a transcoder resource is unavailable, which is needed if the remote sites use different codecs.

Common mistakes.

• B. If the remote phone did not have the conference feature assigned, it typically wouldn't allow the user to initiate a conference at all, rather than failing during the call setup with this specific error.
• C. A software conference bridge must be assigned for ad hoc conferencing to function, and if it were entirely missing, the conference would not start, but the specific error points to resource availability during an active attempt.
• D. A Media Termination Point (MTP) is typically used for DTMF interworking or to allow H.323 devices to connect to SIP-based conferences, but its absence would not directly cause a 'Cannot complete conference call' error related to codec issues in an ad hoc conference.

Concept tested. Ad-hoc conference call codec mismatch and transcoder requirement
