It is now possible to do service virtualization on outbound web-service calls.
In order to do this, you must first activate a new enhancement point in the recording which will capture the outbound web-service calls as linkages against the objects that instigate them. The data captured is the request header and body of the outbound web-service calls.
Then, during the playback, a separate enhancement point for outbound web-services must be activated. When the object is triggered by the bot in the playback, any outbound web-service calls will not actually go out to the external system, but will instead be immediately passed back the same data as that in the recording.
