SIP_FAST_UPDATE_INTER
VAL_ENV 
Default setting is 0 to prevent the Collaboration Server 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 Collaboration Server 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).
SIP_FAST_UPDATE_INTER
VAL_EP
Default setting is 6 to let the Collaboration Server 
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 Collaboration Server send the Intra request to 
Microsoft OC endpoints only.
Enter 0 to disable this behavior at the endpoint level (not 
recommended).
SIP_FREE_VIDEO_RESOU
RCES
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.
SIP_TCP_PORT_ADDR_ST
RATEGY
Setting the flag to 1 prevents the use of two sockets for one 
SIP call - one for inbound traffic, one for outbound traffic. This 
is done by inserting port “5060/5061” into the Route[0] header.
Possible values:
• 0 - Inbound traffic on port 5060/5061 outbound traffic on 
port 60000
• 1 - Both inbound and outbound traffic on port 5060/5061 
Default: 1
SITE_NAME_TRANSPAREN
CY
(MPM+ Only)
In MPM+ Mode this flag is used to enable or disable 
transparency (50%) of the Site Name in the video layout.
Set the value of this flag to NO to disable Site Name 
Transparency.
Default: YES.
In MPMx Mode this function is controlled using the Profile -
Site Names dialog box.
Note: From Version 8.1, MPM+ Media card is not supported.
