Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 105

A new solution is configured to support internal, local, and international calling. Calling [+44 1111 1111] from one of the registered internal phones does not work. Local and internal calls seem to work without any problems. The configuration has patterns configured to match the failing dialed number [+44 …. ….]. The other configured patterns show [2…] for internal numbers and [555 …] for local numbers. International numbers use E.164 as recommended. What is missing to make this solution work?

Answer options

• A. 001 or 00 must be used instead of the + sign on Cisco UCM
• B. =+ cannot be used in a route pattern, only in a SIP pattern
• C. \ in front of the +
• D. / in front of the +

Correct answer: C

Explanation

The correct answer is C because in Cisco UCM, a backslash (") is used to escape the plus sign (+) in dialing patterns. This allows the system to correctly interpret the international dialing format. Options A and B are incorrect as they do not address the issue of the + sign specifically, while option D does not use the correct escape character.
