CVOICE Chapter7 まとめ Part1

- Digit manipulation is the task of adding or subtracting digits from the original dialed number to accommodate user dialing habits or gateway needs.

- Digit stripping strips any outbound digits that explicitly match the destination pattern of a particular dial peer.

- Digit forwarding specifies the number of digits that must be forwarded to a telephony interface.

- Digit prefixing adds digits to the front of the dial string before it is forwarded to a telephony interface.

- Number expansion is applied globally to all calls, not just to calls matching a single designated dial peer.

- By default, when a terminating router matches a dial string to an outbound POTS dial peer, the router strips off the left-justified digits that explicitly match the destination pattern.

- You can use the clid command to modify caller ID information.

- You can use voice translation profiles to replacethe Cisco Unified CME dialplan-pattern command.

- Configuring digit manipulation might require the use of basic commands as well as translation rules and profiles.

- The call routing logic on Cisco IOS routers using the H.323 protocol relies on the dial peer construct.

- Routers must match the correct inbound and outbound dial peers to successfully complete a call.
