Details
The requested destination, although valid, cannot be
reached.
The sending equipment (sending the cause)
is requested to route the call through an unrecognized
transit network.
The called user cannot be reached because the
network does not serve the destination.
The last identified channel is not acceptable to the
sending entity.
The incoming call is connected to a channel already
established for similar calls (e.g. packet-mode X.25
virtual calls).
This call is being cleared by one of the users involved.
The called user cannot accept another call although
compatibility is established.
The user does not respond to call establishment
messages with either an alerting or connect indication
within the allowed time.
The user has provided an alerting indication but no
connect indication within the allowed time.
