Disabling WebEx Meetings
The wt.meeting.centerURL property provides the URL for the WebEx server. To disable WebEx meetings, remove this property from wt.properties.
You can remove the wt.meeting.centerURL property by undefining it using the xconfmanager utility.
In the following example, the wt.meeting.centerURL property is undefined and then the change is propagated:
xconfmanager --undefine wt.meeting.centerUrl
xconfmanager -p
* 
You must issue the xconfmanager -p command to ensure the modification is propagated.
