Recording Links list and the Conference Profile - Recording dialog box.
Range: 1 - 100
Default: 20
The maximum data payload size (bytes) transmitted in a single packet over
the network, and should be minimally the MTU_SIZE (see below) to avoid
fragmenting of data packets.
The Collaboration Server sends large amount of data over the network and
may be required to adjust its MTU size according to the network
environment in which it is deployed.
MTU configuration is applicable to Collaboration Servers with RTM-LAN
cards installed only.
Range: 500-20,000. Values outside that range are treated as 1,500.
Default: 1,500
