Definition
The remote equipment received a call with a call
reference that is not currently in use on the
user-network interface.
The receiving equipment is requested to use a
channel that is not activated on the interface for
calls.
The network received a call resume request. The
call resume request contained a Call Identify
information element that indicates that the call
identity is being used for a suspended call.
The network received a call resume request. The
call resume request contained a Call Identify
information element that indicates that it is in use
for a suspended call.
The network received a call resume request when
there was not a suspended call pending. This
might be a transient error that will be resolved by
successive call retries.
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.
Indicates that an attempt was made to connect to
non-ISDN equipment, for example, to an analog
line.
The ISDN exchange was asked to route the call
through an unrecognized intermediate network.
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.
