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). What it usually means: The SPIDS may be incorrectly entered in the router or http://pbxbook.com/other/isdncode.html the Telco switch, giving a SPID failure in the router logs. The ISDN phone number being dialed by the router is invalid and the telco switch cannot locate the number to complete the call. On long distance calls, the call cannot be properly routed to its destination. 2No route to specified transit network (national use). 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 not serve the equipment which is sending this cause. 3No route to destination. The called party cannot be reached because the network through which the call has been routed does not serve the destination desired. Support for this cause is network dependent. 4Send special information tone. The called party cannot be reached for reasons that are of a long term nature, and the special information tone should be returned to the calling party. 5Mis-dialed trunk prefix (national use). Indicates the erroneous inclusion of a trunk prefix in

The ISDN disconnect 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 sip cause code safe use of debugs. Here is a sample output of the 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.
