Refer to the exhibit. What is the output displayed on the IP phone when the incoming calling number is 00492288224002 and has a TON = unknown?
The correct answer is C. 00492288224002. Transformation patterns and calling party normalization rules in CUCM typically act on calls with a specific Type of Number (TON), such as 'International' or 'National.' When the TON is set to 'unknown,' the number does not match the conditions required to trigger a…

Explanation
Transformation patterns and calling party normalization rules in CUCM typically act on calls with a specific Type of Number (TON), such as 'International' or 'National.' When the TON is set to 'unknown,' the number does not match the conditions required to trigger a transformation (e.g., stripping leading '00' and prepending '+'), so it passes through unmodified. The IP phone therefore displays the raw number exactly as received: 00492288224002. If the TON were set to 'International,' the configured pattern might strip '00' and prefix '+', yielding +492288224002, but that does not apply here.
