Cause value 99

[0x63/0xE3]

Information element non-existent or not implemented

Cause

The equipment that sent this cause value receives a message that includes Information Element not recognized or implemented by the equipment sending the cause value. However, the Information Element is optional in the message, and the equipment that sent the Cause Value does not parse the Information Element to process the message.

This Cause Value has local significance only. The ISDN network between the user and the equipment generating the cause value sends:

  • A no-cause indication through the network

  • A more generic Cause Value through the network

Proposed Solution

Procedure

  1. Check if the protocols at each end of the interface match, for example, both sides are AT&T Custom or both sides are NI-2. If the ends of the interface are using different protocols, the protocols are used with different Information Element encoding.
  2. Check Communication Manager administration for the cause value generated by the network.
    1. Sending connected number information with the domestic custom Information Element identity encoding (0C), but international encoding (4C) is expected.
