SEND_SIP_BUSY_UPON_RESO
URCE_THRESHOLD
When set to YES, it enables the Collaboration Server to send a busy
notification to a SIP audio endpoint or a SIP device when dialing in to
the Collaboration Server whose audio resource usage exceeded the
Port Usage threshold.
When set to NO, the system does limit the SIP audio endpoint
connections to a certain capacity and will not send a busy notification
when the resource capacity threshold is exceeded.
Default: NO
SEND_SRTP_MKI Enables or disables the inclusion of the MKI field in SRTP packets sent
by the Collaboration Server. Setting the value to NO to disables the
inclusion of the MKI field in SRTP packets sent by the Collaboration
Server.
Set this flag to:
•NO
When all conferences on the RMX will not have MS-Lync clients
participating and will have 3rd party endpoints participating.
When using endpoints (eg. CounterPath Bria 3.2 Softphone) that
cannot decrypt SRTP-based audio and video streams if the MKI
(Master Key Identifier) field is included in SRTP packets sent by
the Collaboration Server.
This setting is recommended for Maximum Security Environments.
• YES
When any conferences on the RMX will have both MS-Lync
clients and Polycom endpoints participating.
Some 3rd party endpoints may be unsuccessful in participating
in conferences with this setting.
Notes:
• This System Flag must be added and set to YES (default) when
Microsoft Office Communicator and Lync Clients are used as they all
support SRTP with MKI.
• The system flag must be added and set to NO when Siemens
phones (Openstage and ODC WE) are used in the environment as
they do not support SRTP with MKI.
• Polycom endpoints function normally regardless of the setting of this
flag.
Default: YES
SEND_WIDE_RES_TO_IP When set to YES
(default), the Collaboration Server sends wide screen
reso
lution to IP endpoints. Endpoint types that do not support wide
screen resolutions are automatically identified by the Collaboration
Server according to their product type and version and will not receive
the wide resolution even when the flag is set to YES.
When manually added and set to NO, the Collaboration Server does
not send wide screen resolution to all IP endpoints.
Default: YES.
