SEND_SIP_BUSY_UPON_R
ESOURCE_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.
Set the value to NO to disable the inclusion of the MKI field in
SRTP packets sent by the Collaboration Server 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.
Notes:
•This System Flag must be set to YES (default) when HDX
endpoints, 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.
Default: YES
