Chapter 20-System Configuration Flags
Polycom, Inc. 20-31
SIP_FORMAT_GW_HEADE
RS_FOR_REDCOM
Controls whether the RMX adds special gateway prefix and
postfix characters to the user portion of the SIP URI
expressed in the “From” and “Contact” headers of SIP
messages sent during calls involving Gateway Services. The
addition of these characters can result in call failures with
some SIP call servers. It is recommended to set this flag to
YES whenever the RMX is deployed such that it registers its
conferences to a SIP call server.
Range: YES, NO
Default: NO
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
SOCKET_ACTIVITY_TIMEO
UT
For use in Microsoft environments.
When the MS_KEEP_ALIVE System Flag is set to YES, the
value of this flag is used as the MS Keep-Alive Timer value.
SUPPORT_HIGH _PROFILE Enables or disables the support of High Profile video protocol
in CP conferences. This flag is specific to CP conferences
and has no effect on VSW conferences.
Range: YES / NO
Default: YES
TC_BURST_SIZE This flag regulates the Traffic Control buffer or maxburst size
as a percentage of the participant line rate.
Range: 1-30.
TC_LATENCY_SIZE This flag limits the latency (in milliseconds) or the number of
bytes that can be present in a queue.
Range: 1-1000 (in milliseconds).
