Table 21-2 Manually Added System Flags – MCMS_PARAMETERS (Continued)
Flag Description
RMX_MANAGEMENT_SEC
URITY_PROTOCOL
Enter the protocol to be used for secure communications.
Default: TLSV1_SSLV3 (both).
Default for U.S. Federal licenses: TLSV1.
SEND_SRTP_MKI Enables or disables the inclusion of the MKI field in SRTP
packets sent by the RMX.
Set the value to NO to disable the inclusion of the MKI field in
SRTP packets sent by the RMX when using endpoints (eg.
CounterPath Bria 3.2 Softphone) that cannot decrypt SRTPbased
audio and video streams if the MKI (Master Key
Identifier) field is included in SRTP packets sent by the RMX.
Note: This System Flag should not be set to NO when HDX
endpoints, Microsoft Office Communicator and Lync Clients
are used as they all support SRTP with MKI.
Default: YES
SIP_ENABLE_FECC By default, FECC support for SIP endpoints is enabled at the
MCU level. You can disable it by manually adding this flag and
setting it to NO.
SIP_FAST_UPDATE_INTER
VAL_ENV
SIP_FAST_UPDATE_INTER
VAL_EP
SIP_FREE_VIDEO_RESOU
RCES
Default setting is 0 to prevent the RMX from automatically
sending an Intra request to all SIP endpoints.
Enter n (where n is any number of seconds other than 0) to let
the RMX automatically send an Intra request to all SIP
endpoints every n seconds.
It is recommended to set the flag to 0 and modify the
frequency in which the request is sent at the endpoint level
(as defined in the next flag).
Default setting is 6 to let the RMX automatically send an Intra
request to Microsoft OC endpoints only, every 6 seconds.
Enter any other number of seconds to change the frequency
in which the RMX send the Intra request to Microsoft OC
endpoints only.
Enter 0 to disable this behavior at the endpoint level (not
recommended).
For use in Avaya and Microsoft Environments.
When set to NO (required for Avaya and Microsoft
environments), video resources that were allocated to
participants remain allocated to the participants as long as
they are connected to the conference even if the call was
changed to audio only. The system allocates the resources
according to the participant’s endpoint capabilities, with a
minimum of 1 CIF video resource.
Enter YES to enable the system to free the video resources
for allocation to other conference participants. The call
becomes an audio only call and video resources are not
guaranteed to participants if they want to add video again.
Default value in Microsoft environment: NO.
