Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 45

Which process can localize a global E.164 with + prefix calling numbers for inbound calls to an IP phone so that users see the calling number in a local format?

Answer options

• A. Calling number localization is done using translation patterns.
• B. Calling number localization is done using route patterns.
• C. Calling number localization is done by configuring a calling party transformation CSS at the phone.
• D. Calling number localization is done by configuring a calling party transformation CSS at the gateway.
• E. Calling number localization is done by configuring the phone directory number in a localized format.

Correct answer: C

Explanation

The correct answer is C because configuring a calling party transformation CSS at the phone allows for the specific formatting of the calling number for that device. The other options either pertain to different types of patterns or configurations that do not specifically target the phone's local display of the calling number.
