Video calls using 384 kbps need to be supported across a gatekeeper-controlled trunk. What value should be entered into the gatekeeper to support this bandwidth? (SourcE. Configuring Cisco Unified Video Advantage)
A. 768 kbps
B. 384 kbps
C. 512 kbps
D. 192 kbps
Correct Answer: B
Explanation/Reference:
Explanation: Incorrect answer : ACD
Explanation : A 384-kb/s video call may comprise G.711 at 64 kb/s (for audio) plus 320 kb/s (for video). This sum does not include overhead. If the audio codec for a video call is G.729 (at 24 kb/s), the video rate increases to maintain a total bandwidth of 384 kb/s.
