Considerations for Authorization Codes

Last Updated : Oct 30, 2012 |

This section provides information about how the Authorization Codes feature behaves in certain circumstances. Use this information to ensure that you receive maximum benefits of the Authorization Codes feature under all conditions:

  • From remote locations users usually access authorization from touch-tone telephones. However, users can also do so from rotary telephones at specified authorization-code-forced locations that follow appropriate trunk administration practices. Rotary station users access attendants using Listed Directory Numbers (LDN) or Remote Access Numbers (RAN), and can experience a 10-second timeout.

  • The use of Authorization Codes does not limit other call-control methods, such as Toll Restriction, Miscellaneous Trunk Restriction, and Outward Restriction.

  • For security reasons, do not assign authorization codes in sequential order. Assign random number barrier codes and authorization codes to users. Random codes prevent hackers from deciphering the sequential codes.

  • If timeout to attendant does not occur or a Cancellation of Authorization Code Request (CACR) digit codes are dialed instead of authorization codes, the system assumes that invalid authorization codes were dialed and the caller hears intercept tones.

  • Authorization codes can have an impact calling privileges. Authorization codes can:

    • Change the FRL of an outgoing call when the FRL is not high enough to access preferred that AAR/ARS assigns. An FRL is assigned to a COR that is associated with user authorization codes. No additional COR data is assigned.

    • Overrides COR for remote access calls that are assigned to barrier codes, when required. if an authorization code is required for remote access calls, the user is assigned the COR of the dialed authorization code, with all connected data, such as the FRL. This COR overrides the COR that is assigned to any required barrier code.

    • Override the COR that is associated with a VDN, if an authorization code is required. The COR of the Authorization code is applicable on this call.

      The Authorization Code COR overrides the Barrier Code COR, the Barrier Code COR in turn overrides the VDN COR, and the VDN COR in turn overrides the COR of the originator.

  • Incoming trunk calls that require authorization codes retain user privileges.
