ISDN NetCause und SIP-Codes
Diese Liste habe ich aus verschiedenen Quellen zusammengesucht und hier primäre als Referenz für meine eigenen Recherchen. Denn wenn ich mit Gateway arbeite und per ISDN (S0 oder S2m) anbindet, dann finde ich immer wieder solche "NetCause"-Codes, die ich dann einer Meldung zuordnen muss. einige davon sind "normale" Codes, wie z.B. 16 (Remote Disconnect).
Die Informationen auf dieser Seite habe ich aus verschiedenen Quelle, z.B. RFCs, Produktinformationen von Gateway-Herstellern etc. zusammen gesammelt und hier als Liste aufbereitet.
Die verschiedenen Codes werden in Klassen eingeteilt:
CLASS 1.1 (normal)
CLASS 1.2 (Resource unavailable)
CLASS 1.3 (service or option not available)t
CLASS 1.4 (Service or option not implemented)
CLASS 1.5 (Invalid message; e.g. parameter out of range)
CLASS 1.6 (Protocol error; e.g. Unknown message)
CLASS 1.7 (Interworking class)
Nicht definiert. Fehlimplementierung oder proprietäre Anlagenmeldungen.
SIP-Gateways müssen diese Codes entsprechend auf SIP-Meldungen umsetzen.
Unallocated (unassigned) numberCheck
No route to specified transit network
(national use) /Prefix 0 dialed in error
No route to destination/Prefix 1 dialed in
send special information toneThis 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.
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 premises equipment.
channel unacceptableThis cause indicates that the channel most recently identified is not acceptable to the sending entity für use in this call.
call awarded. being delivered in an established channelThis 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).
Call is proceeding/PreemptionThis cause indicates the call is being preempted.
normal call clearingThis 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.
Excess digits received, call is proceeding
Far end disconnect (Normal call clearing)
user busyThis 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.
no user respondingThis 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.
no answer from user (user alerted)
subscriber absentThis 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.
call rejectedThis 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.
number changedThis 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.
non-selected user clearingThis cause indicates that the user has not been awarded the incoming call.
destination out of orderThis 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.
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 not complete.
facilities rejectedThis cause is returned when a supplementary service requested by the user cannot be provide by the network.
response to STATUS INQUIRYThis cause is included in the STATUS message when the reason für generating the STATUS message was the prior receipt of a STATUS INQUIRY.
normal. UnspecifiedThis cause is used to report a normal event only when no other cause in the normal class applies.
no circuit/channel availableThis cause indicates that there is no appropriate circuit/channel presently available to handle the call.
Call Queued [Q.850]
network out of orderThis cause indicates that the network is not functioning correctly and that the condition is likely to last a relatively long period of time e.g., immediately re-attempting the call is not likely to be successful.
permanent frame mode connection out-of-serviceThis cause is included in a STATUS message to indicate that a permanently established frame mode connection is out-of-service (e.g. due to equipment or section failure) (see Annex A/Q.933)
permanent frame mode connection operationalThis cause is included in a STATUS message to indicate that a permanently established frame mode connection is operational and capable of carrying user information. (see Annex A/Q.933]
temporary failureThis cause indicates that the network is not functioning correctly and that the condition is no likely to last a long period of time; e.g., the user may wish to try another call attempt almost immediately.
switching equipment congestionThis cause indicates that the switching equipment generating this cause is experiencing a period of high traffic.
access information discardedThis cause indicates that the network could not deliver access information to the remote user as requested. i.e., user-to-user information, low layer compatibility, high layer compatibility or sub-address as indicated in the diagnostic. It is noted that the particular type of access information discarded is optionally included in the diagnostic.
requested circuit/channel not availableThis cause is returned when the circuit or channel indicated by the requesting entity cannot be provided by the other side of the interface.
precedence call blockedThis cause indicates that there are no predictable circuits or that the called user is busy with a call of equal or higher preventable level.
resource unavailable, unspecifiedThis cause is used to report a resource unavailable event only when no other cause in the resource unavailable class applies.
Quality of Service not availableThis cause is used to report that the requested Quality of Service. as defined in Recommendation X.213. cannot be provided (e.g., throughput of transit delay cannot be supported).
requested facility not subscribedThis cause indicates that the user has requested a supplementary service which is implemented by the equipment which generated this cause but the user is not authorized to use.
outgoing calls barred
outgoing calls barred within CUGThis cause indicates that although the calling party is a member of the CUG für the outgoing CUG call. Outgoing calls are not allowed für this member of the CUG.
incoming calls barred
incoming calls barred within CUGThis cause indicates that although the calling party is a member of the CUG für the incoming CUG call. Incoming calls are not allowed für this member of the CUG.
bearer capability not authorizedThis cause indicates that the user has requested a bearer capability which is implemented by the equipment which generated this cause but the user is not authorized to use.
bearer capability not presently availableThis cause indicates that the user has requested a bearer capability which is implemented by the equipment which generated this cause but which is not available at this time.
inconsistency in outgoing information element.This cause indicates an inconsistency in the designated outgoing access information and subscriber class
service or option not available. UnspecifiedThis cause is used to report a service or option not available event only when no other cause in the service or option not available class applies.
bearer capability not implementedThis cause indicates that the equipment sending this cause does not support the bearer capability requested.
channel type not implementedThis cause indicates that the equipment sending this cause does not support the channel type requested
requested facility not implementedThis cause indicates that the equipment sending this cause does not support the requested supplementary services.
only restricted digital information bearer capability is available (national use)This cause indicates that the calling party has requested an unrestricted bearer service but the equipment sending this cause only supports the restricted version of the requested bearer capability.
service or option not implemented unspecifiedThis cause is used to report a service or option not implemented event only when no other cause in the service or option not implemented class applies.
invalid call reference valueThis cause indicates that the equipment sending this cause has received a message with a call reference which is not currently in use on the user-network interface.
identified channel does not existThis cause indicates that the equipment sending this cause has received a request to use a channel not activated on the interface für a call. für example. if a user has subscribed to those channels on a primäry rate interface numbered from l to 12 and the user equipment or the network attempts to use channels l 3 through 23, this cause is generated.
a suspended call exists, but this call identify does notThis cause indicates that a call resume has been attempted with a call identity which differs from that in use für any presently suspended call(s).
call identity in useThis cause indicates that the network has received a call suspended request containing a call identity (including the null call identity) which is already in use für a suspended call within the domain of interfaces over which the call might be resumed.
no call suspendedThis cause indicates that the network has received a call resume request containing a Call identity information element which presently does not indicate any suspended call within the domain of interfaces over which calls may be resumed.
call having the requested call identity has been clearedThis cause indicates that the network has received a call resume request containing a Call identity information element indicating a suspended call that has in the meantime been cleared while suspended (either by network time-out or by the remote user).
user not a member of CUGThis cause indicates that the called user für the incoming CUG call is not a member of the specified CUG or that the calling user is an ordinary subscriber calling a CUG subscriber.
incompatible destinationThis cause indicates that the equipment sending this cause has received a request to establish a call which has low layer compatibility. high layer compatibility or other compatibility attributes (e.g., data rate) which cannot be accommodated.

mandatory information element is missingThis cause indicates that the equipment sending this cause has received a message which is missing an information element which must be present in the message before that message can be processed.
message type non-existent or not implementedThis cause indicates that the equipment sending this cause has received a message with a message type it does not recognize either because this is a message not defined of defined but not implemented by the equipment sending this cause.
message not compatible with call state or message type non-existent or not implemented.This cause indicates that the equipment sending this cause has received a message such that the procedures do not indicate that this is a permissible message to receive while in the call state. or a STATUS message was received indicating an incompatible call state.
Information element / parameter non-existent or not implementedThis cause indicates that the equipment sending this cause has received a message which includes information element(s)/parameter(s) not recognized because the information element(s)/parameter name(s) are not defined or are defined but not implemented by the equipment sending the cause. This cause indicates that the information element(s)/parameter(s) were discarded. However, the information element is not required to be present in the message in order für the equipment sending the cause to process the message.
Invalid information element contentsThis cause indicates that the equipment sending this cause has received and information element which it has implemented; however, one or more Gelds in the I.E. are coded in such a way which has not been implemented by the equipment sending this cause.
