Options

A+49128822400
B491288224002
C00492288224002
D+492288224002

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.
