3. Enable the SIP penalty box feature by setting the sipPenaltyBoxEnable variable to enable .
The penalty box is always “active”. This means that even if the feature is disabled, IP addresses are
marked as invalid, but they are still tried. This has the advantage that when the feature is enabled,
IP addresses that were already marked as invalid are instantly put into the penalty box.
Publication Parameters
The following describes publication parameters and behaviours you can configure.
Refreshing Publications
You can refresh the publications, i.e., commit the changes you have done to the publications. When refreshing
the publications, all enabled endpoints unpublish themselves from the previous Presence Compositor and
send a new publication to the current Presence Compositor with the current parameters.
Variables whose modification require a registration refresh are:
sipPresenceCompositorStaticHost
sipPresenceCompositorStaticPort
X
To refresh the publications:
1. In the sipMIB , locate the sipPublicationCmdRefresh variable.
The following values are available:
• noOp: No operation.
• refresh: Refresh publications.
2. Define the time, in seconds, at which the User Agent begins refreshing its publication before the
publication expiration in the
sipPublicationRefreshTime variable.
A publication is valid for a period of time specified by the Presence Compositor. The User Agent is
then responsible for refreshing its previously established publications before their expiration interval
has elapsed.
For instance, if the publication lasts 60 minutes and this variable is set to 43, the unit sends new
PUBLISH requests 59 minutes and 17 seconds after the reception of the publication
acknowledgement (43 seconds before the end of the publication period).
Setting this variable to 0 means that the User Agent falls into the 'unpublished' state BEFORE
sending the refreshing PUBLISH request.
Publications Expiration
The SIP protocol allows an entity to specify the “expires” parameter of a contact in a PUBLISH request. The
server can return this “expires” parameter in the 200 OK response or select another “expires”. In the PUBLISH
request, the “expires” is a suggestion the entity makes.
The “expires” parameter indicates how long, in seconds, the user agent would like the binding to be valid.
You can configure the “expires” parameter the Mediatrix 1204 sends.
X
To configure the publications expiration:
1. In the sipMIB , set the sipPublicationProposedExpirationValue variable with the suggested
expiration delay, in seconds, of a publication in the PUBLISH request.
Keep in mind that this is only a suggestion and that servers will decide the publication time following
local policy.
