A phone is assigned to a partition that is included in the CSS HQ-Phone. This partition contains a route pattern to block calls to service numbers 1-400-xxx-xxxx. When the engineer makes a test call to the number 1-400-400-9000 from that phone, the call goes through. What is the reason for this issue?

A.	The route pattern for the number to be blocked is in partition not accessible to the CSS.
B.	The correct route list is not selected in the route pattern for the dialed number to be blocked.
C.	The correct gateway is not selected for the route list for the route pattern for the dialed number to be blocked.
D.	The route pattern for the number to be blocked is in "NULL" partition.
E.	The route pattern is misconfigured.
