Answer: A

QUESTION 150
Refer to the exhibit. IT shows an H.323 gateway configuration in a Cisco Unified Communications Manager environment. An inbound PSTN call to this H.323 gateway fails to connect to IP phone extension 2001. The PSTN user hears a reorder tone. Debug isdn q931 on the H.323 gateway shows the correct called-party number as 5015552001.

Which two configuration changes can correct this issue? (Choose two.)

A.    Add port 1/0:23 to dial-peer voice 123 pots.
B.    Ensure that the Significant Digits for inbound calls on the H.323 gateway configuration is 4.
C.    Add a voice translation profile to truncate the number from 10 digits to 4 digits. Apply the voice translation profile to the Voice-port. The configuration field “Significant Digits for inbound calls” is left at default (All).
D.    Add the command h323-gateway voip id on interface vlan120.
E.    Change the destination-pattern on the dial-peer voice 23000 VoIP to 501501? and change the Significant Digits for inbound calls to 4.

Answer: BE
Explanation:
Choose the number of significant digits to collect, from 0 to 32. Cisco Unified Communications Manager counts significant digits from the right (last digit) of the number that is called.

QUESTION 151
Which device is needed to integrate H.320 into the Cisco video solution?

A.    video gateway
B.    MGCP gateway
C.    H.323 gatekeeper
