A video conference between two sites shows severe macroblocking on the far-end video. The audio is clear. The network team checks the video RTP stream and sees 3% packet loss. The video is H.264 at 1080p. The link is a 100 Mbps MPLS circuit at 30% utilization. The video is marked AF41 and audio is EF. The router has LLQ for EF and CBWFQ for AF41. What is the most likely cause of the video packet loss?

The EF queue is stealing bandwidth from video

The AF41 queue is dropping packets due to a low bandwidth allocation

The video codec is not compatible with the receiving endpoint

The link is congested at 30% utilization

A video call experiences periodic freezing. The network shows low packet loss but high jitter. Which adjustment is most likely to reduce the freezing?

Increase the jitter buffer size

A user in a remote office reports that they can make calls but cannot hear the far end. The phone registers successfully and calls connect. You check the call manager and see the call is active with media flowing. The remote office uses a NAT firewall. What is the most likely cause?

The phone's firmware is outdated

The call manager is not configured for the remote site

The NAT firewall is not translating RTP ports correctly

The far end is using a different codec
