Cause value 100

Invalid information element contents

Cause

The equipment that sends this cause value receives a message with an Information Element that can be recognized and implemented by the equipment. However, one or more of the fields in the Information Element are coded in a manner that the Information Element is not implemented by the equipment sending this cause value.

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 diagnostics for the IE identifier of the Information Element that contains the information that violates protocol.

    The PROGRESS INDICATOR IE information that Communication Manager generates must not affect call completion. There is no way to modify how Communication Manager generates this information.
