Q30Media and QoS
A network administrator with ID0123456789 has determined that a WAN link between two Cisco UCM clusters provides only 1 Mbps of bandwidth for voice traffic. How many calls can this link support when G.711 is used as the audio codec?

I think if you round it 1000/80=12.5, but if you want to be more accurate, 1024x1024/87.2=12.036 which will be the same thing, that is closer to 12.

This is CAC question. Le'ts say we use 1 Mbps that is 1024. CUCM for g711 subtracts 84 kbps from remaining bandwidth that was allocated. 1024/84 gives 12,19. This means CAC wouldn't allow 13th call to be placed, and options such as AAR could be triggered.

G.711 bandwidth per call should be 87.2 Kbps so i'd think the answer would be 11? what am i doing wrong?

Selected Answer: A
1024\87.2=11.74. A would be the nearest match
