Denial Events
Cause Value 98
[0x62/0xE2] -
Message type, not compatible with call state, or non-existent, or not implemented
The equipment that sent this Cause Value received a message, and the procedures in the
protocol specification indicate that this is not a permissible message to receive while in this call
state. A STATUS message was received indicating an incompatible call state.
This Cause Value has local significance only. The ISDN network between the user and the
equipment generating the Cause Value might:
● Send no cause indication through the network
● Send a more generic Cause Value through the network

● Check that 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 running different
protocols, they might be running with different call state machines, or different message
type encoding.
● Check the diagnostic information generated by Communication Manager for the message
type identifier of the message that violates protocol. See Table 53: Cause Value 97, 98,
101 Diagnostic Information on page 191.
● Call state problems are reported with STATUS messages. The equipment sending the
Cause Value uses the CALL STATE IE of the STATUS message to indicate the call state.
To determine the call state of the other end of the interface, run the message sequence of
the call through the SDL flow charts of the appropriate side (user or network) and the
appropriate protocol (TR41449/41459, TR1268, A211 etc.). If the call state at the other end
of the interface does not agree with that reported in the STATUS message and both sides
are already running the same protocol, then a problem with the implementation of the state
machine exists on either side.
