Adjusting MTU of Data Packets
Data 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 data 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.
