Correct Answer: CDF Section: QoS Explanation
Voice traffic uses UDP packets for network transfer and normally they are sensitive to delay (Latency) because its real time traffic.Voice traffic can be benign as well.

How does the Cisco Unified Communications Manager Express match an outbound VoIP dial peer?
A. Outbound dial-peer matching uses the entire string of digits en bloc to match the dial peer with the longest match.
B. Outbound dial-peer matching is completed on a digit-by-digit basis.
C. It matches outbound dial peers by placing all the dial peers into a hunt group and then uses the entire dialed number en bloc to match the first dial peer.
D. Cisco Unified Communications Manager Express creates a hunt group that contains all the configured dial peers and then applies the dial digits in a digit-by-digit manner to match a dial peer.
Correct Answer: A Section: CUCME Explanation
Explanation/Reference: The method a router uses to select an outbound dial peer depends on whether DID is configured in the inbound POTS dial peer. If DID is not configured in the inbound POTS dial peer, the router collects the incoming dialed string digit by digit. When one dial peer is matched, the router immediately places the call using the configured attributes in the matching dial peer. If DID is configured in the inbound POTS dial peer, the router uses the full incoming dial string to match the destination pattern in the outbound dial peer. With DID, the setup message contains all the digits necessary to route the call; no additional digit collection is required. If more than one dial peer matches the dial string, all of the matching dial peers are used to form a rotary group. The router attempts to place the outbound call leg using all of the dial peers in the rotary group until one is successful.
