Definition
The equipment received a message of a type that is
invalid or not supported. This code indicates either a
problem with the remote configuration or a problem with
the local D channel.
The equipment received a message that is not valid in
the current call state. Cause 98 is usually due to a
D-channel error. If this error occurs systematically,
report it to your ISDN service provider.
The 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.
The equipment received a message that includes
invalid information in the information element. This is
usually due to a D-channel error.
The remote equipment received a message that does
not correspond to the current state of the connection.
This is usually due to a D-channel error.
A time-out has triggered an error-handling (recovery)
procedure. This problem is typically temporary.
An unspecified D-channel error when no other standard
cause applies.
An event occurred within a network that does not
provide causes for the action that it takes. The precise
problem is unknown.
User needs to check cabling, ISDN adapter status and
network connections.
There is either a switch protocol error, or (in the United
States or Canada) a SPID assignment problem.
The ISDN signaling code has encountered an error
processing an ISDN action. ISDN adapter busy-wait
and retry.
