Question
An engineer must configure a new Cisco UCM translation pattern to convert 915555555555 into 1665. Which translation pattern must be used?
A. Translation pattern: 91555555555.5
Called-party transformation discard digits: PreDot
Called-party transformation prefix digits: 166
B. Translation pattern: 91555555.5555
Called-party transformation discard digits: PreAt
Calling-party transformation prefix digits: 1665
C. Translation pattern: 9155555555.55
Called-party transformation discard digits: PreDot
Calling-party transformation mask: 1665
D. Translation pattern: 915555555.555
Called-party transformation discard digits: None
Calling-party transformation prefix digits: 5
Answer
The correct answer is A. To configure a Cisco UCM translation pattern that converts 915555555555 into 1665, you should use the following settings:
Translation pattern: 91555555555.5
Called-party transformation discard digits: PreDot
Called-party transformation prefix digits: 166
Explanation
The translation pattern 91555555555.5 matches the original number 915555555555. The .5 at the end of the pattern is a wildcard that matches any single digit.
By setting the “Called-party transformation discard digits” to “PreDot,” the UCM will remove all the digits before the dot (.) in the matched number. In this case, it will discard 91555555555, leaving only the last digit matched by the wildcard (5).
Finally, by configuring the “Called-party transformation prefix digits” as 166, the UCM will prepend these digits to the remaining portion of the number. The resulting transformed number will be 1665.
The other options are incorrect because:
- Option B uses an incorrect translation pattern that does not match the original number.
- Option C uses the “Calling-party transformation mask” instead of the “Called-party transformation prefix digits,” which is not suitable for this scenario.
- Option D does not discard any digits and only prefixes 5, which would result in an incorrect transformed number.
Therefore, option A provides the correct translation pattern and transformation settings to convert 915555555555 into 1665 in Cisco UCM.
