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.
The MTU parameter on the system is described below.
