This section provides information about how the Caller ID feature behaves in certain circumstances. Use this information to ensure that you receive the maximum benefits of Caller ID under all conditions. The following consideration apply to Caller ID:
If you use Incoming Caller ID on analog trunks that are connected to a Direct Inward and Outward Dialing (DIOD) central office (CO) trunk media module, do not put these trunks in an outgoing Automatic Alternate Routing (AAR) or an Automatic Route Selection (ARS) route pattern. The loop-start trunks that the DIOD CO trunk media module supports do not provide answer supervision. Thus, the potential for toll fraud exists.
