Fix Recommendation

[IP][ISDN]; Perform the following tasks:

- Configure the VTU to display the source of the incoming call and to the extent possible, the identity of the caller, such that the user can make an informed decision to answer the call or not.
- Maintained directories with current information regarding user information related to other VTUs with which the VTU is expected to communicate unless calling VTUs provide the caller information along with the source information.
- Train users to not answer incoming calls from unknown sources in the event doing so could disclose sensitive or classified information in the area of the VTU.
- Train users to not answer incoming calls from unknown sources or sources that may not have appropriate clearance or a need-to-know during a conference since doing so could improperly disclose sensitive or classified information to the caller.
