Which of these reasons can cause intrasite calls within a Cisco Unified Communications Manager cluster to fail?
A. The route partition that is configured in the CCD requesting service is not listed in the calling phone CSS
B. The trunk CSS does not include the partition for the called directory number.
C. The MGCP gateway is not registered
D. The calling phone does not have the correct CSS configured
E. The calling phone does not have the correct partition configured.
Correct Answer: D
Explanation/Reference:
Explanation- To make a successful call within CUCM cluster following condition should satisfy. No CSS, No partitions are used for call routing, default call routing hence any phone can call any phone within same CUCM cluster.
If we want to configure call restriction then CSS and partitions are must, if we don’t configure required partition in CSS then call will not be successful.
