Description
Enables you to override the RMX resolution selection and limit
it to a lower resolution, hence minimizing the resource usage
to 1 or 1.5 video resources per call instead of 3 resources.
Possible flag values are:
AUTO (default), QCIF, CIF, VGA or HD720.
This flag indicates the debugging level for system support.
The flag's values have been modified for version 7.8 and is
not backward compatible with previous versions.
Possible values:
From version 7.8 - TRACE = t, DEBUG = d, INFO_NORMAL
= n, INFO_HIGH = i, WARN = w, ERROR = e, FATAL = f, OFF
= o.
From version 7.7 or lower - TRACE = n/a, DEBUG = n/a,
INFO_NORMAL = n, INFO_HIGH = api, WARN = n/a,
ERROR = crt, FATAL = n/a, OFF = no.
Default: n
The maximum number of Recording Links available for
selection in the Recording Links list and the Conference
Profile - Recording dialog box.
Range: 1 - 100
Default: 20
MTU size (Maximum Transmission Unit controls the maximum
data payload size (bytes) transmitted in a single packet over
the network.
The RMX 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 RMXs with RTM-LAN
cards installed only.
Default: 1500
Used to set the threshold line rate for HD Resolution Content :
the line rate at which the RMX will send Content at HD1080
Resolution. Setting the flag to 0 disables HD Resolution
Content.
Default: 768 kbps.
Low quality, low frame rate video is prevented from being sent
to endpoints by ensuring that an SD channel is not opened at
frame rates below the specified value.
Range: 0 -30
Default: 15
