86 Call having the requested call identity has been cleared
The network has received a Call Resume request for a call ID
which once corresponded with a suspended call, but the call
was cleared while still suspended. It may have been cleared
either by the network timing out or by a remote user.
88 Incompatible destination
The equipment has received a request to establish a call to a
destination which cannot handle the required compatibility
attributes (e.g. data rate).
91 Invalid transit network selection
95 Invalid message, unspecified
This cause is used to report that a message is invalid, only
when no other cause in the ‘invalid message’ class applies.
96 Mandatory information element is missing
The equipment has received a message with one or more
mandatory information elements missing, and therefore cannot
process the message.
97 Message type non-existent or not implemented
The equipment has received a message of a type it does not
recognise, either because the message is undefined or because
it is not implemented by the equipment.
98 Message not compatible with call state, or message type
non-existent or not implemented
The equipment has received a message which it considers to be
not permissible while in the call state; or a Status message that
indicates an incompatible call state.
99 Information element non-existent or not implemented
The equipment has received a message containing an
information element which is not recognised; either because
its ID is not defined or because it is not implemented by the
equipment. However, the equipment can still process the
message without the information element.
100 Invalid information element contents
The equipment has received an information element which it
has implemented. However, the contents are incorrectly coded
(e.g. truncated, invalid extension bit, invalid field values, etc.).
