this cause does not recognize the transit network either because the transit network does not exist or because that particular cause code technologies transit network. While it does exist. does not serve the equipment which is sending this cause. Cause No. 3 - No route to destination [Q.850] This cause indicates that the called party cannot be sip cause codes 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. Cause No. 4 - send special information tone [Q.850] This cause indicates that the called party cannot be reached for reasons that are of a long term nature and that the special information tone should be returned to the calling party.

No. 5 - misdialed trunk prefix (national use) [Q.850] 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. Cause No. 6 - channel unacceptable [Q.850] This cause indicates that the channel most recently identified is not acceptable to the sending entity for use in this call. Cause No. 7 - call awarded. being delivered in an established channel [Q.850] 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 for similar calls (e.g. packet-mode x.25 virtual calls). Cause No. 8 - preemption [Q.850] This cause indicates the call is being preempted. Cause No. 9 - preemption - circuit reserved for reuse [Q.850] This cause indicates that the call is being preempted and the circuit is reserved for reuse by the preempting exchange. Cause No. 10 - normal call clearing [Q.850] 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.

The ISDN disconnect cause code cause code appears in the debug isdn q931 command output, and indicates the reason for call disconnection. Note:Activate the debug isdn q931 command for this exercise. Remember that the debug isdn q931 command generates a large volume of debugs. Refer to Important Information on Debug Commands for more information on the safe use of debugs. Here is a sample output of the isdn cause code debug isdn q931 command. The output indicates the disconnect cause code for a failed ISDN call: Calling#ping 10.10.10.2 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.10.10.2, timeout is 2 seconds: 20:52:14: ISDN BR0: TX -> SETUP pd = 8 callref = 0x2E 20:52:14: Bearer Capability i = 0x8890 20:52:14: Channel ID i = 0x83 20:52:14: Keypad Facility i = '5551111' 20:52:15: ISDN BR0: RX <- CALL_PROC pd = 8 callref = 0xAE 20:52:15: Channel ID i = 0x89 20:52:16: ISDN BR0: RX <- PROGRESS pd = 8 callref = 0xAE 20:52:16: Progress Ind i = 0x8A81 - Call not end-to-end ISDN, may have in-band info 20:52:16: Signal i = 0x01 - Ring back tone on 20:52:34: ISDN BR0: RX <- DISCONNECT pd = 8 callref = 0xAE 20:52:34: Cause i =0x829F08 - Normal,unspecified or Special intercept, call blocked group restriction 20:52:34: ISDN BR0: TX -> RELEASE pd = 8 callref = 0x2E 20:52:34: ISDN BR0: RX <- RELEASE_COMP pd = 8 callref = 0xAE The 0x in the disconnect code indicates that the subsequent b
codes are also known as: ISDN Event Cause Codes Bellcore Standard ISDN Cause Codes SS7 Cause Codes Note: Installer password required for this feature This feature is useful for diagnostic purposes. It shows the reason why an ISDN call has been released. Normally, you will use one of the following settings: Text: None (default) or Detailed The most commonly seen codes are 16 (normal disconnect) and 17 (busy). The Q.931 Cause Values are grouped into the following classes: Normal events: Cause 1-31 Resource unavailable: Cause 32-47 Service or option not available: Cause 48-63 Service or option not implemented: Cause 64-79 Invalid message: Cause 80-95 Protocol error: 96-111 Internetworking: Cause 112-127 Cause codes and definitions: Cause No. 1: Unallocated (unassigned number). This cause indicates that the destination requested by the calling user cannot be reached because, although the number is in a valid format, it is not currently assigned (allocated). Cause No. 2: no route to specified transit network. 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 network, while it does exist, does not serve the equipment that is sending this cause. This cause is supported on a network-dependent basis. Cause No. 3: no route to destination. This cause indicates that the called user 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. Cause No. 6: channel unacceptable. This cause indicates that the channel used in this call is not acceptable to the sending entity. Cause No.7: call awarded and being delivered in an established channel. This cause indicates that the user is receiving an incoming call, which is being connected to a channel already used by t
