17 | USER BUSY |
18 | NO USER RESPONDING (The SBC may release a call with this cause value if: - The CAS SSP that is executed on an egress call does not have WAIT ANSWER configured as the last step in the sequence. This token is typically configured to await an off hook at the Far-End. In this case, this token is performed by default with a 30 second timeout. If this timer expires then this code is returned.
- ISDN User Part (ISUP) for an Egress Call releases a call because of an Address Complete Message (ACM) timeout from the SGX. In this case, the SGX forwards Q.931 code 31 (NORMAL UNSPECIFIED) to the PSTN switch.
- In general, SBC times out waiting for an ISUP ACM or ALERTING or CON message after sending Initial Address Message (IAM) SETUP)
|
19 | NO ANSWER FROM USER (SBC may release a call with this cause value if ISUP for an egress call releases call because releasescallbecause of ANM timeout from SGX. In this case, the SGX forwards Q.931 code 102 (RECOVERY ON TIMER EXPIRY) to PSTN switch) |

- ISDN circuits were reset via CLI command, causing all calls on those circuits to be brought down.
- ISDN Channels were restarted by the Far-End switch bringing down all calls on those circuits.
- CAS circuits were reset via CLI command, causing all calls on those circuits to be brought down.
- Any other CLI command, such as a command to take a T1 or CNS out of service, causes all calls on those circuits to go down.

- attempts to reroute call ("crankback"), but is out of routes or out of routes with available circuits. An attempt to reroute call may have various causes. When this is the result of an attempted reroute, the cause value triggering the reroute is placed into accounting record.
- A software programming error occurred.

38 | NETWORK OUT OF ORDER The may release a call with this cause value if:- Gateway-to-Gateway Signaling Link to Far-End is lost due to network problems or CLI command. In either event, all calls to that are cleared with this disconnect reason.
- Gateway-to-Gateway Signaling Link to Far-End went down and then back up. Afterwards, the s audit saudit all calls between them. Any mismatched calls are brought down with this disconnect reason.

41 | TEMPORARY FAILURE [Sonus Ribbon codes 131, 132, and 136 are mapped to this ID. This mapping is performed before the ISUP Release Message is sent out. The "underlying" Sonus Ribbon code is placed into the accounting record.] The may release a call with this cause value if:- Communication between and PSX is broken and Policy Requests from the to the PSX time out.
- A Policy Request issued from the to the PSX was rejected by the PSX because of corrupted data in the packet - an indication of possible network problems.
- A software programming error occurred.
- ISUP calls were brought down as a result of corrective action ofcorrectiveaction that was performed following a Circuit Query with a Far-End PSTN Switch.
- Connectivity to SS7 Gateway is lost and all active SS7 Calls in the are brought down.
- The received a UCIC ISUP Message from a Far-End PSTN Switch that contained a CIC of an active call.
- Call admission on is suspended due to CNS Failure, switchover, standby card synchronization, no NTP time, or other issues. All new call admission requests from other s over Gateway-to-Gateway signaling are released to originating tooriginating gateway with this code.
- Catastrophic failure such as a CNS failure or a PNS failure occurs on a and all affected calls are released. The releases these calls back to the originating gateway over the gateway-to-gateway signaling link with this code.
- T8 Timer expires in ISUP. This timer expires if does not receive a COT message from previous switch within T8 Timer duration, when the IAM indicates that a COT is being performed.
In general when is not getting responses from PSX, this indicates IP network congestion or PSX overload. Both are transient conditions that will resolve themselves, hence the use of this code to indicate a temporary failure situation.
