/*! \page AstCauses Hangup Causes for Asterisk
The Asterisk hangup causes are delivered to the dialplan in the
${HANGUPCAUSE} channel variable after a call (after execution
of "dial").
In SIP, we have a conversion table to convert between SIP
return codes and Q.931 both ways. This is to improve SIP/ISDN
compatibility.
These are the current codes, based on the Q.931
specification:
- AST_CAUSE_UNALLOCATED 1
- AST_CAUSE_NO_ROUTE_TRANSIT_NET 2
- AST_CAUSE_NO_ROUTE_DESTINATION 3
- AST_CAUSE_CHANNEL_UNACCEPTABLE 6
- AST_CAUSE_CALL_AWARDED_DELIVERED 7
- AST_CAUSE_NORMAL_CLEARING 16
- AST_CAUSE_USER_BUSY 17
- AST_CAUSE_NO_USER_RESPONSE 18
- AST_CAUSE_NO_ANSWER 19
- AST_CAUSE_CALL_REJECTED 21
- AST_CAUSE_NUMBER_CHANGED 22
- AST_CAUSE_DESTINATION_OUT_OF_ORDER 27
- AST_CAUSE_INVALID_NUMBER_FORMAT 28
- AST_CAUSE_FACILITY_REJECTED 29
- AST_CAUSE_RESPONSE_TO_STATUS_ENQUIRY 30
- AST_CAUSE_NORMAL_UNSPECIFIED 31
- AST_CAUSE_NORMAL_CIRCUIT_CONGESTION 34
- AST_CAUSE_NETWORK_OUT_OF_ORDER 38
- AST_CAUSE_NORMAL_TEMPORARY_FAILURE 41
- AST_CAUSE_SWITCH_CONGESTION 42
- AST_CAUSE_ACCESS_INFO_DISCARDED 43
- AST_CAUSE_REQUESTED_CHAN_UNAVAIL 44
- AST_CAUSE_PRE_EMPTED 45
- AST_CAUSE_FACILITY_NOT_SUBSCRIBED 50
- AST_CAUSE_OUTGOING_CALL_BARRED 52
- AST_CAUSE_INCOMING_CALL_BARRED 54
- AST_CAUSE_BEARERCAPABILITY_NOTAUTH 57
- AST_CAUSE_BEARERCAPABILITY_NOTAVAIL 58
- AST_CAUSE_BEARERCAPABILITY_NOTIMPL 65
- AST_CAUSE_CHAN_NOT_IMPLEMENTED 66
- AST_CAUSE_FACILITY_NOT_IMPLEMENTED 69
- AST_CAUSE_INVALID_CALL_REFERENCE 81
- AST_CAUSE_INCOMPATIBLE_DESTINATION 88
- AST_CAUSE_INVALID_MSG_UNSPECIFIED 95
- AST_CAUSE_MANDATORY_IE_MISSING 96
- AST_CAUSE_MESSAGE_TYPE_NONEXIST 97
- AST_CAUSE_WRONG_MESSAGE 98
- AST_CAUSE_IE_NONEXIST 99
- AST_CAUSE_INVALID_IE_CONTENTS 100
- AST_CAUSE_WRONG_CALL_STATE 101
