5.16.2.2. Service Information 
LCR rerouting is a different feature to Call Forward Rerouting. LCR
rerouting (V_CAUSE_ACCEPT_REROUTE) is executed, upon detection of the
following situations (Disconnect / Release Causes).
- Cause no. 3: No route to destination (DB_CV_NO_ROUTE_TO_DEST) e.g. No dial plan entry" for the number dialed in the partner system.
- Cause no. 6: Channel unacceptable (DB_CV_CHNL_NOT_ACCEPTABLE) e.g. B-Channel negotiation incorrect.
- Cause no. 8: Unable to render embedded object: File (Proprietary) not found. Outgoing call barred (DB_CV_OUTGONG_CALLS_BARRED) e.g. No LCR authorization for outgoing calls.
- Cause no. 33: Circuit out of order (DB_CV_CIRCUIT_OUT_OF_ORDER) e.g. Circuit fault / Out of operation.
- Cause no. 34: No circuit/channel available (DB_CV_NO_CIRC_CHL_AVAIL) e.g. No valid / Idle circuit available.
- Cause no. 38: Network Out of Order (DB_CV_NETW_OUT_OF_ORDER) e.g. Network fault.
- Cause no. 41: Temporary failure (DB_CV_TEMP_FAILURE) e.g. Insufficient information for call setup in the remote system.
- Cause no. 42: Switching equipment congestion (DB_CV_SWITCH_EQUIP_CONG) e.g. Lack of resources at partner.
- Cause no. 44: Requested circuit/channel not available (DB_CV_RQ_CIRC_CHL_NO_AVAIL).
- Cause no. 47: Resource unavailable (DB_CV_RESOURCE_UNVAIL).
- Cause no. 63: Service or option not available (DB_CV_SERV_OPT_NOT_AVAIL) e.g. Line is available, but does not correspond to the requirements on the connection.
- Cause no. 82: Identified channel does not exist (DB_CV_ID_CHL_DOES_N_EXST) e.g. The channel requested does not exist.
- Cause no. 102: Recovery on timer expiry (DB_CV_REC_TIMER_EXPIRY) e.g. No response within a defined period.
- Cause no. 127: Interworking, unspecified (DB_CV_INTERWORKING).
- Cause no. 140: Unable to render embedded object: File (Proprietary) not found. Network congestion (DB_CV_NETW_CONGESTION).
If the parameter TGRE is set in the COT of a circuit, Rerouting is only
performed for causes:
- Cause no. 1: Unallocated (unassigned) number (DB_CV_UNASSIGNED_NR).
- Cause no. 3: No route to destination (DB_CV_NO_ROUTE_TO_DEST).
- Cause no. 22: Number changed (DB_CV_NUMBER_CHANGED).
- Cause no. 44: Requested circuit/channel not available (DB_CV_RQ_CIRC_CHL_NO_AVAIL)
If the parameter TGRE is set in the COT of a circuit with ZANDE OPTFEA 160
active, Rerouting is only performed for causes:
- Cause no. 1: Unallocated (unassigned) number (DB_CV_UNASSIGNED_NR).
- Cause no. 17: User busy (DB_CV_USER_BUSY).
- Cause no. 18: No user responding (DB_CV_NO_USER_RESPONDING).
- Cause no. 21: Call rejected (DB_CV_CALL_REJ).
- Cause no. 31: Normal, unspecified (DB_CV_NORM_UNSPECIFIED).
- Cause no. 41: Temporary failure (DB_CV_TEMP_FAILURE).
