ACCESS_INFO_DISCARDED

The network cannot provide the requested access information.

BEARERCAPABILITY_NOTAUTH

The user requested a bearer capability that the network provides, but the user is not authorised to use it. This might be a subscription problem.

The network normally provides the requested bearer capability, but it is unavailable at the present time. This might be due to a temporary network problem or to a subscription problem.

BEARERCAPABILITY_NOTIMPL

The network cannot provide the bearer capability requested by the user.

CALL_AWARDED_DELIVERED

The user is assigned an incoming call that is being connected to an already-established call

CALL_REJECTED

The destination is capable of accepting the call but rejected the call for an unknown reason.

CHAN_NOT_IMPLEMENTED

The network or the destination equipment does not support the requested channel type.

CHANNEL_UNACCEPTABLE

The service quality of the specified channel is insufficient to accept the connection.

DESIGNATION_OUT_OF_ORDER

The destination cannot be reached because the interface is not functioning correctly, and a signalling message cannot be delivered. This might be a temporary condition, but it could last for an extended period of time. For example, the remote equipment might be turned off.

FACILITY_NOT_IMPLEMENTED 

The remote equipment does not support the requested supplementary service.

FACILITY_NOT_SUBSCRIBED

The remote equipment supports the requested supplementary service by subscription only.

FACILITY_REJECTED

The facility requested by the user cannot be provided by the network.

IE_NONEXIST

The remote equipment received a message that includes information elements, which were not recognized. This is usually due to a D-channel error. If this error occurs systematically, report it to your ISDN service provider.

INCOMPATIBLE_DESTINATION

The network received a call resume request. The call resume request contained a Call Identity information element, which once indicated a suspended call. However, the suspended call was cleared either by timeout or by the remote user.

INTERWORKING

An event occurred, but the network does not provide causes for the action that it takes. Problem is unknown.

INVALID_CALL_REFERENCE

The remote equipment received a call with a call reference that is not currently in use on the user-network interface.

INVALID_IE_CONTENTS

The remote equipment received a message that includes invalid information in the information element. This is usually due to a D-channel error.

INVALID_MSG_UNSPECIFIED

An invalid message was received, and no standard cause applies. This is usually due to a D- channel error. If this error occurs systematically, report it to your ISDN service provider.

INVALID_NUMBER_FORMAT

The connection could be established because the destination address was presented in an unrecognisable format or because the destination address was incomplete.

MANDATORY_IE_MISSING

The receiving equipment received a message that did not include one of the mandatory information elements. This is usually due to a D-channel error. If this error occurs systematically, report it to your ISDN service provider.

MESSAGE_TYPE_NONEXIST

The receiving equipment received an unrecognized message, either

NETWORK_OUT_OF_ORDER

The destination cannot be reached because the network is not functioning correctly, and the condition might last for an extended period of time. An immediate reconnect attempt will probably be unsuccessful.

An error occurred because the network is not functioning correctly. The problem will be resolved shortly.

NORMAL_CIRCUIT_CONGESTION

The connection cannot be established because no appropriate channel is available to take the call.

NO_ROUTE_DESTINATION

The call was routed through an intermediate network that does not serve the destination address.

NO_ROUTE_TRANSIT_NET

The ISDN exchange is asked to route the call through an unrecognised intermediate network.

NO_USER_RESPONSE

The connection cannot be completed because the destination doesn’t not respond to the call.

NUMBER_CHANGED

The ISDN number used to set up the call is not assigned to any system.

PROTOCOL_ERROR

An unspecified D-channel error when no other standard cause applies.

RECOVERY_ON_TIMER_EXPIRE

An error-handling (recovery) procedure was initiated by a timer expiry. This is usually a temporary problem.

RESPONSE_TO_STATUS_ENQUIRY

The status message was generated in direct response to the prior receipt of a status enquiry message.

REQUESTED_CHAN_UNAVAIL

The remote equipment cannot provide the requested channel for an unknown reason. This might be a temporary problem.

SWITCH_CONGESTION

The destination cannot be reached because the network switching equipment is temporarily overloaded.

UNALLOCATED

The ISDN number was sent to the switch in the correct format; however, the number is not assigned to any destination equipment.

USER_BUSY

The called system acknowledges the connection request but is unable to accept the call because all B channels are in use.

WRONG_CALL_STATE

The remote equipment received an unexpected message that does not correspond to the current state of the connection. This is usually due to a D-channel error.

WRONG_MESSAGE

The remote equipment received an invalid message, and no standard cause applies. This cause is due to a D-channel error. If this error occurs systematically, report it to your ISDN service provider.
