An engineer with ID012345678 must build an international dial plan in Cisco Unified Communications Manager. Which action should be taken when building a variable-length route pattern?
A. reduce the T302 timer to less than 4 seconds
B. configure single route pattern for international calls
C. create a second route pattern followed by the # wildcard
D. set up all international route patterns to 0.!
The question is not about how to reduce the post-dial delay but about how to build a variable length pattern, therefore D is the right answer.
“International destinations are usually configured by using the exclamation (!) wildcard which represents any quantity of digits, also referred as variable-length patterns”
Correct answer is C
International and Variable-Length Route Patterns
Reduce the T302 timer to indicate end of dialing, but do not set it lower than 4 seconds to prevent premature transmission of the call before the user is finished dialing.
Configure a second route pattern followed by the # wildcard and instruct the users to dial # to indicate end of dialing.
