Refer to the exhibit. Assume that the HQ phones have access to the HQ partition, and BR phones
have access to the BR partition. Which set of implementations would best address the overlapping
directory number extensions for intersite (WAN) calling between the HQ site and the BR site?

A.
Configure a route pattern 8222.[12]XXX for site HQ, and assign it to partition HQ. Configure the
called party DDI of Predot.
Configure a route pattern for site BR 8111.[1-3]XXX, and assign it to partition BR. Configure called
party DDI Predot.
Use the local gateway at each site. Prefix the appropriate site code for the calling number.

B.
Configure a single route pattern for both sites 8[12,12,12].[1-32]XXX. Use a route list that contains
the local route group for each site. Prefix the appropriate site code for the calling number.

C.
Configure a translation pattern 8222.[12]XXX for site HQ, and assign it to partition HQ. Use a CSS
that contains the partitions for BR phones.
Configure a translation pattern 8111.[1-3]XXX for site BR, and assign it to partition BR. Use a CSS that
contains the partitions for HQ phones.
For both translation patterns, configure the called party DDI of Predot. Prefix the appropriate site
code for the calling number.

D.
Configure a translation pattern 8222.[12]XXX for site HQ, and assign it to partition BR. Use a CSS
that contains the partitions for HQ phones.
Configure a translation pattern 8111.[1-3]XXX for site BR, and assign it to partition HQ. Use a CSS
that contains the partitions for BR phones.
For both translation patterns, configure the called party DDI of Predot. Prefix the appropriate site
code for the calling number.
