Cisco 300-815 Question Answer

Refer to the exhibit. An engineer deploys CAC to Cisco UCM. UptofiveG.711 calls must be supported on the WAN link between Site A and Site B. Users report that only four concurrent calls are possible between Site A and Site B. Why isn't the filth concurrent call successful?

The G.729 audio codec is negotiated between Site A and B instead of the G.711 codec.

The QoS configuration on the WAN link causes the fifth call to be dropped.

Cisco UCM is using alternative links because of the Weight value.

The Audio Bandwidth value is undersized and must be set to 400 kbps.
