Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 32

How does an administrator make a Cisco IP phone display the last 10 digits of the calling number when the call is in the connected state, and also display the calling number in the E.164 format within call history on the phone?

Answer options

• A. Configure a translation pattern that has a Calling Party Transform Mask of XXXXXXXXXX.
• B. On the inbound SIP trunk, change Significant Digits to 10.
• C. Change the service parameter Apply Transformations On Remote Number to True.
• D. Configure a calling party transformation pattern that keeps only the last 10 digits.

Correct answer: D

Explanation

The correct answer is D because configuring a calling party transformation pattern to keep only the last 10 digits directly addresses the requirement for displaying the last 10 digits of the calling number. Option A does not achieve the desired outcome as it masks the number rather than transforming it. Option B only affects the number of significant digits on the trunk but does not transform the display format. Option C modifies a service parameter that does not specifically deal with the display of the last 10 digits.
