Recovery

  1. This output indicates that a SCCP message was discarded because it failed screening.
    No action is necessary, unless the message should have passed. If the message should have passed (verified by the fields displayed in the above message), continue with 2.
  2. Using the rtrv-scr-cgpa command, verify the screen name specified in the output does not allow SCCP messages.
    Check the following fields in the output:
    • For non-SCMG messages, check the SCCP MT, SSN, and OPC.
    • For SCMG messages, check the TYPE, AFTSS, and AFTPC (or OPC if the AFTPC is not present).
  3. If the SCCP message should have passed screening, use the ent-scr-cgpa or chg-scr-cgpa command to add the appropriate information to the screening reference.
