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.

Before you begin

Update host or IP addresses only after new addresses have been published by IBM®.

About this task

Sametime Gateway uses a custom property called server to store Fully qualified domain names (FQDN) or host IP addresses of instant messaging services. The property enables Sametime Gateway to determine when a SIP request is coming from AOL Instant Messenger or Office Communications Server.. The property is pre-set when you add an external community that uses one of the aforementioned services, so if a FQDN or a host IP addresses changes, you must update the custom property for any community that relies on that service.

Note that you can change only the custom property at the community level after you create the connection to a community.

Procedure

1. Log into the Integrated Solutions Console and click Sametime Gateway > Communities.
2. Click a community that uses the translation protocol that you want to update:

   Translation protocol	Instant messaging provider
   SIP for AOL	AOL Instant Messenger
   SIP for Lync/OCS	Office Communications Server

3. Click Custom properties.
4. Click servers.
5. In the Value field, edit the host names or IP addresses.
6. Click OK.
7. Repeat the preceding steps for other communities that use the same translation protocol (SIP for AOL, SIP for Lync/OCS, or XMPP).
8. Restart the Sametime Gateway Server, or, if you have a cluster of Sametime Gateway Servers, restart the cluster.
