The attendant uses the Attendant Intrusion feature to announce a new call or a message to a user who is already on a call.
When the attendant releases the call of the user, the source party either waits at the analog telephone of the user, or holds on an available line appearance on a digital telephone.
Note:
Only one call can be waiting at a time. If a call is already waiting on the telephone of the intruded party, the source party, once split from the attendant, cannot also wait.
