Any numbers dialed as "????" are now barred from making calls. The attempted call will be shown as barred in "My Messages". This must be used with the existing Workspace Desktop Edition Dial Plan feature. For example, if the WDE is configured with dial-plan-rule-1=1234=>???? and if the agent dials 1234, the call will be barred. No request will be sent to T-Server. All the barring will be handled within the WDE.
Single-step transfers and conferences of IM calls to a destination with a directly entered number are forbidden unconditionally. This barring of directly dialed destinations for single-step transfers and conferences will not be reported in "My Messages".
