ISDN hangup cause codes
eduguru 0 Comments (similar to cause 88). Some part of the format being used is not understood by either the remote side equipment or the switching equipment between the source and destination of the call. Code No. 97 -, a physical layer or data link layer failure at the remote party or user equipment off-line. Code No. 28 - invalid number format (address incomplete). This cause indicates that the called party cannot , all Telcos have their own system for programming the number formats that the switches will recognize. Some systems want to see 7 digits, although the number is in a valid format, and cause 100. Code No. l - Unallocated (unassigned) number. This cause indicates that the destination requested by the calling user cannot be reached because, and others 11. Code No. 52 - outgoing calls barred. Code No. 53 - outgoing calls barred within CUG. This cause indicates that although the calling party is a member of the CUG for the outgoing CUG cal, as defined in Recommendation X.213. cannot be provided (e.g., as it is invalid. 3. On long distance calls, but at this time they are proprietary in nature. The PRI equipment vendors are the most likely to use these codes as they have been using proprietary messages in the facilities data link for some time, but if it doesn't happen in the time allotted by the switch programming, but the reasons for it could be: 1. Bad username or password 2. Router's settings do not match what is expected by the remote end. 3. Telephone line problems. 4. Hung session on remote end. Code No. 1, but this call identify does not. This cause indicates that a call resume has been attempted with a call identity which differs from that in use for any presently suspended call(s). Code No. 84 - call , cause 88, Code No. 1, data rate) which cannot be accommodated. What it means: 1. This usually means that the Number To Dial in the Connection Profile is in the wrong format. You may need to dial a 10 or 11 digit number, dialing at 64K when only 56K is supported. Code No. 66 - channel type not implemented. This cause indicates that the equipment sending this cause does not support the channel type requested. Code No. , for example, giving a SPID failure in the router logs. 2. The ISDN phone number being dialed by the router is invalid and the telco switch cannot locate the number to complete the call, 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. Code No. 44 - req, if a user has subscribed to those channels on a primary rate interface numbered from l to 12 and the user equipment or the network attempts to use channels 3 through 23, if the equipment sending this cause is an intermediate point, immediately re-attempting the call is not likely to be successful. Code No. 39 - permanent frame mode connection out-of-service. This cause is included in a STATUS message to indicate that a permanent, 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 for rejection. What i, ISDN hangup cause codes, ISDN hangup cause codes provide information as to why a call has been terminated. The list of hangup cause codes below provides detailed information as to the underlying cause behind a call hangup: Co, it is not currently assigned (allocated). What it usually means: 1. The SPIDS may be incorrectly entered in the router or the Telco switch, low layer compatibility, one or more of the fields in the information element are coded in such a way which has not been implemented by the equipment sending this cause. What it means: Like cause 1 and cause 88, or a call will fail with this cause. Code No. 101 - message not compatible with call state. This cause indicates that a message has been received which is incompatible with the call state. Code No. 10, or a misconfiguration on the equipment being called. Code No. 22 - number changed. This cause is returned to a calling party when the called party number indicated by the calling party is no longer as, or a STATUS message was received indicating an incompatible call state. Code No. 99 - Information element / parameter non-existent or not implemented. This cause indicates that the equipment sending t, or dial a 9 in front of the number if it is a Centrex line. 2. This problem may also give a Cause 111. 3. Dialing at the wrong line speed can also give this Cause. Code No. 90 - non-existent CUG. This, some 10, the call cannot be properly routed to its destination. Code No. 2 - No route to specified transit network (national use). This cause indicates that the equipment sending this cause has received a requ, the call should be placed properly. There are no standards for this, the call will not ring through and will be discarded by the switch. Code No. 103 - parameter non-existent or not implemented - passed on (national use). This cause indicates that the equipment sending, the information element is not required to be present in the message in order for the equipment sending the cause to process the message. Code No. 100 - Invalid information element contents. This caus, the number being called is not an ISDN number but an analog destination. 2. The equipment is dialing at a faster rate than the circuitry allows, the router relinquishes the second channel, the Telco switch operates a timer. For example, the user may wish to try another call attempt almost immediately. What it means: This means that there is a temporary failure at the physical layer on the ISDN network. If you remove the ISDN cable fr, then this cause indicates that the parameter(s) were passed unchanged. Code No. 110 - message with unrecognized parameter discarded. This cause indicates that the equipment sending this cause has disc, this cause is generated. Code No. 83 - a suspended call exists, this usually indicates that the ISDN number being dialed is in a format that is not understood by the equipment processing the call. SPIDs will sometimes fail to initialize with a Cause 100, throughput of transit delay cannot be supported). Code No. 50 - requested facility not subscribed. This cause indicates that the user has requested a supplementary service which is implemented by the , unallocated (unassigned) number shall be used. Code No. 26 - non-selected user clearing. This cause indicates that the user has not been awarded the incoming call. Code No. 27 - destination out of ord, unspecified. This cause indicates that an interworking call (usually a call to 5W56 service) has ended. Notes about Cause Codes over 128 Cause code values of 128 and higher aren't sent over the networ, unspecified. This cause is used to report a protocol error event only when no other cause in the protocol error class applies. Code No. 127 - Intel-working, unspecified. This cause is used to report a resource unavailable event only when no other cause in the resource unavailable class applies. Code No. 49 - Quality of Service not available. This cause is, unspecified. This cause is used to report an invalid message event only when no other cause in the invalid message class applies. Code No. 96 - mandatory information element is missing. This cause ind, user-to-user information, when an analog call is placed to a Netopia router that has two B Data Channels in place, which can be caused by a bad switch translation, you would see this. It's usually temporary. Code No. 42 - switching equipment congestion. This cause indicates that the switching equipment generating this cause is experiencing a period of high traff
