Configuring Sametime Gateway
properties
You can put limits on sessions and subscriptions, and specify
blacklist domains to check when Sametime® Gateway Server
receives a subscription request. You can also add or edit custom properties
for communities, connections, translation protocols, or message handlers.
Setting the blacklist domains
You can specify the DNS blacklisted sites to check when
the IBM Sametime Gateway Server
receives a subscription request. A blacklisted domain is an email
address domain that you do not want to give access to through Sametime Gateway Server.
Setting a session timeout for an external community
Setting a session timeout applies to the instant messaging
capability only. By default, the session timeout is set on the translation
protocol only and disabled at the external community level. Note that
setting a community session to timeout may cause instant messaging
sessions to expire, terminate, or be lost.
Setting a session timeout for a translation protocol
A session timeout applies to instant messaging sessions
only, not presence, and to the following translation protocols: SIP
for Sametime Gateway,
SIP for AOL, SIP for Lync/OCS (Office Communications Server), and
SIP for legacy Sametime Gateway.
By default, this property is set on the translation protocol, but
you can set the property at the community level.
Setting a subscription timeout for an external community
Setting a subscription timeout applies only to the presence
capability when connecting to a community using the SIP for legacy Sametime Gateway protocol.
The subscription timeout cancels or re-subscribes a SIP-based presence
session.
Setting an internal subscription timeout for an external community
Setting an internal subscription timeout allows you to
define a subscription timeout if an external community does not set
a timeout through the SIP Expires header. An internal subscription
timeout also overrides any existing subscription timeout defined by
an external community.
Setting subscription timeouts for a translation protocol
Setting a subscription timeout applies only to the presence
capability. The subscription timeout cancels or re-subscribes a SIP
for legacy Sametime Gateway
presence session.
Customizing the error message for when instant messaging fails
You can create and display custom text for users when an
instant message fails.
Updating the external community host addresses
Complete these steps to update the server IP addresses
that Sametime Gateway
uses to determine when SIP requests originate from AOL Instant Messenger
pr Office Communications Server/Lync Server.
Translation protocol additions
You can extend the IBM Sametime Gateway Server
by adding translation protocols. Additional translation protocols
expand the communities that the Sametime Gateway Server
can connect with.
