Unallocated (unassigned) numberCheck
number, redial
This cause indicates that the called party cannot be reached
recluses although the called party number is in a valid format.
It is not currently allocated (assigned). |
2 | No route to specified transit network
(national use) /Prefix 0 dialed in error
This cause indicates that the equipment sending this cause has
received a request to route the call through a particular
transit network which it does not recognize. The equipment
sending this cause does not recognize the transit network either
because the transit network does not exist or because that
particular transit network. While it does exist. does not serve
the equipment which is sending this cause. |
3 | No route to destination/Prefix 1 dialed in
error
This cause indicates that the called party cannot be reached
because the network through which the call has been routed does
not serve the destination desired. This cause is supported on a
network dependent basis. |
4 | send special information tone
This cause indicates that the called party cannot be reached für reasons that are of a long term nature and that the special
information tone should be returned to the calling party. |
5 | misdialed trunk prefix (national use)
This cause indicates the erroneous inclusion of a trunk prefix
in the called party number. This number is to sniped from the
dialed number being sent to the network by the customer Premisess
equipment. |
6 | channel unacceptable
This cause indicates that the channel most recently identified
is not acceptable to the sending entity für use in this call. |
7 | call awarded. being delivered in an established
channel
This cause indicates that the User has been awarded the incoming
call and that the incoming call is being connected to a channel
already established to that User für similar calls (e.g.
packet-mode x.25 virtual calls). |
8 | Call is proceeding/Preemption
This cause indicates the call is being preempted. |
9 | preemption
circuit reserved für reuse
This cause indicates that the call is being preempted and the
circuit is reserved für reuse by the preempting exchange. |
10 | normal call clearing
This cause indicates that the call is being cleared because one
of the Users involved in the call has requested that the call be
cleared. Under normal situations, the source of this cause is
not the network. |
14 | Excess digits received, call is proceeding
More digits were dialed than expected. Called number has been
truncated to the expected number. |
16 | Far end disconnect (Normal call clearing)
This cause indicates that the call is being cleared because one
of the Users involved in the call has requested that the call be
cleared. Under normal situations, the source of this cause is
not the network |
17 | User busy
This cause is used to indicate that the called party is unable
to accept another call because the User busy condition has been
encountered. This cause value may be generated by the called User or by the network. In the case of User determined User busy
it is noted that the User equipment is compatible with the call. |
18 | no User responding
This cause is used when a called party does not respond to a
call establishment message with either an alerting or connect
indication within the prescribed period of time allocated. |
19 | no answer from User (User alerted)
This cause is used when the called party has been alerted but
does not respond with a connect indication within a prescribed
period of time.
Note: This cause is not necessarily generated
by Q.931 procedures but may be generated by internal network
timers. |
20 | subscriber absent
This cause value is used when a mobile station has logged off.
radio contact is not obtained with a mobile station or if a
personal telecommunication User is temporarily not addressable
at any User-network interface. |
21 | call rejected
This cause indicates that the equipment sending this cause does
not wish to accept this call. although it could have accepted
the call because the equipment sending this cause is neither
busy nor incompatible. This cause may also be generated by the
network, indicating that the call was cleared due to a
supplementary service constraint. The diagnostic field may
contain additional information about the supplementary service
and reason für rejection. |
22 | number changed
This cause is returned to a calling party when the called party
number indicated by the calling party is no longer assigned. The
new called party number may optionally be included in the
diagnostic field. If a network does not support this cause,
cause no. 1, unallocated (unassigned) number shall be used. |
26 | non-selected User clearing
This cause indicates that the User has not been awarded the
incoming call. |
27 | destination out of order
This cause indicates that the destination indicated by the User
cannot be reached because the interface to the destination is
not functioning correctly. The term "not functioning correctly"
indicates that a signal message was unable to be delivered to
the remote party; e.g., a physical layer or data link layer
failure at the remote party or User equipment off-line. |
28 | invalid number format (address incomplete)
This cause indicates that the called party cannot be reached
because the called party number is not in a valid format or is
