When an incoming PSTN call arrives at an MGCP gateway, how does the calling number get
normalized to a global E.164 number with the + prefix in Cisco Unified Communications Manager?
A.
Normalization is done using translation patterns.
B.
Normalization is done using route patterns.
C.
Normalization is done using the gateway incoming called party prefixes based on number type.
D.
Normalization is done using the gateway incoming calling party prefixes based on number type.
E.
Normalization is achieved by local route group that is assigned to the MGCP gateway.
Explanation:
Incorrect answer: ABCE
Configuring calling party normalization alleviates issues with toll bypass where the call is routed to
multiple locations over the IP WAN. In addition, it allows Cisco Unified Communications Manager to
distinguish the origin of the call to globalize or localize the calling party number for the phone user.
