New Questions 15

An engineer is planning the voice call bandwidth requirements between two offices. The design requires a capacity of 25 concurrent audio calls using the G.729 codec and lPv6 transport. Which two configurations meet the requirements? (Choose two)

A. required bandwidth 850 kbps, given Ethernet transport, and a 30-byte payload.

B. required bandwidth 975 kbps, given Ethernet transport, and a 20-byte payload.

C. required bandwidth 400 kbps, given Ethernet transport, compressed RTP, and a 30-byte payload.

New Questions 17

Which two SCCP call signaling messages are initiated by Cisco Unified Communications Manager to an lP phone? (Choose two.)

A. SoftKeyEvent

B. CloseReceiveChannelAck

C. CallState

D. KeypadButton

E. OpenReceiveChannel

F. Offhook

Answer: C, E


Upon receiving anOpenReceiveChannelmessage, the lP phone selects the UDP port number it wants to use to receive RTP packets and reports this information to call manager.

With the SCCP protocol architecture, the majority of the H.323 processing power resides in an H.323 proxy - the Cisco CallManager. The end stations (lP phones) run the Skinny client, which consumes less processing overhead. The client communicates with CallManager using connection-oriented (TCP/lP-based) communication to establish a call with another H.323-compliant end station. Once Cisco CallManager has established the call, the two H.323 end stations use connectionless (UDP/lP-based) communication for audio transmissions.
