Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 118

Users dial a 9 before a 10-digit phone number to make an off-net call. All 11 digits are sent to the Cisco Unified Border Element before going out to the PSTN. The
PSTN provider accepts only 10 digits. Which configuration is needed on the Cisco Unified Border Element for calls to be successful?

Answer options

Correct answer: D

Explanation

The correct answer is D, as it effectively matches and removes the leading '9' from the dialed number, allowing only the 10-digit number to be sent to the PSTN. Options A, B, and C attempt to match the entire sequence or include additional characters, which would not produce the required 10-digit output needed by the PSTN provider.
