Adjusting MTU of Video Packets
Video packets that exceed the maximum transmission unit (MTU) size for any router or segment
along the network path may be fragmented or dropped. This results in poor quality video at the
receiving device. You can set the maximum MTU size of the video packets sent by the system.
The default value is 1500 bytes. Specify the MTU size used in calls based on the network
bandwidth settings. If the video becomes blocky or network errors occur, packets may be too
large; decrease the MTU. If the network is burdened with unnecessary overhead; packets may be
too small, increase the MTU.

Specifies the maximum MTU size (in
