QUESTION 321
An engineer is working on a Cisco VCS Control routing configuration and wants users to be able to dial ccnpcollab and have calls routed to [email protected].
Which option achieves this aim?
A. search rules
B. transforms
C. access rules
D. call policy
Answer: B
Explanation:
Although Call Policy could be used, typically this type of alias change is done using transforms (either pre-search transforms or search rule transforms). Call Policy could be justified as the correct answer based on how the question is interpreted. If this change is only intended for the ccnpcollab alias being dialed, and not for other aliases that might be dialed without a domain, then call policy makes since. Still, I would never use Call Policy in this capacity, nor does Cisco recommend this.
