Possible solution
You must configure a proxy server that prevents your organization's BlackBerry Enterprise Server from receiving HTTP
requests from external servers. If the BlackBerry Enterprise Server is located in an unrestricted network that permits direct
HTTP connections to the IBM Lotus Sametime server, the BlackBerry Collaboration Service establishes an HTTP
connection to the IBM Lotus Sametime server automatically to retrieve the phone numbers. If your organization's
BlackBerry Enterprise Server is located in a restricted network that does not permit direct HTTP connections to the IBM
Lotus Sametime server, you must specify an unauthenticated proxy server in the rimpublic.properties file that the
BlackBerry Collaboration Service can use to establish an HTTP connection to the IBM Lotus Sametime server.
1. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution
topology > BlackBerry Domain > Components > Collaboration.
2. Click a BlackBerry Collaboration Service instance.
3. Click Edit instance.
4. On the Proxy mappings tab, configure the settings for an authenticated or unauthenticated proxy server. Use the
default web address.
5. Click the Add icon.
6. Click Save All.
7. To verify that a new entry exists for the BlackBerry Collaboration Service, in the database management console, view
the proxy configuration information for the BlackBerry Configuration Database.
8. If the BlackBerry Enterprise Server is located in a restricted network, perform steps 10 to 14.
9. On the computer that hosts the BlackBerry Collaboration Service, navigate to <drive>:\Program Files\Research In
Motion\BlackBerry Enterprise Server\BBIM\Servers\Instance\Config .
10.In a text editor, open the rimpublic.properties file.
11.Copy the following text into the rimpublic.properties file. Replace <host_name> with the host name of an
unauthenticated proxy server:
[Java Security Property]
networkaddress.cache.ttl=0
improxy.proxy.type=http
improxy.proxy.host=<hostname>
improxy.proxy.port=8080
12.Save and close the rimpublic.properties file.
13.Restart the BlackBerry Collaboration Service.
