The Certkiller Lumber Company would like to use AAR to reroute calls made from HQ to remote locations when those calls are rejected by the IP WAN because of insufficient bandwidth. The Certkiller Lumber Company uses 5-digit dialing to all locations.
Certkiller Headquarters has a DID range from 770-555-0001 to 770-557-0500 and the Macon facility has a DID range from 912-556-0500 to 912-556-0550.How should the external phone masks be configured?
A.
770557XXXX
B.
9125560XXX
C.
770555XXXX
D.
77055XXXXX
E.
912556XXXX
CAlls made from HQ to External facilities wouldnt imply that the AAR number is the one of the external facility?
