Smartnumbers Control has an automatic failover capability which re-routes inbound calls whenever a network outage or congestion is detected which prohibits the normal delivery of calls. The service monitors every call and automatically redirects calls to an alternative destination should delivery problems be experienced.
Calls can be redirected when the following signals are detected:
- Congestion or Network Busy: There is no capacity available.
- Number Unobtainable: The number dialled is not configured correctly.
- Busy: The number dialled is already busy, and there is no voicemail or alternate number to route the call to. Typically this would be returned when a user is already on the phone.
- No Answer: The phone call will be rerouted if not answered within the specified timeout period.
- Other: A failure not covered by above options.
You can set up which failover reasons should trigger calls being redirected for each Control service individually in the Edit dialog accessible from the three-dot menu:
During normal operation the service attempts to deliver each call to a primary destination. If a problem is experienced, the service will automatically try to redirect that same call to a secondary destination. In turn, if a problem is experienced on the secondary route, the service will automatically try to redirect that call to a tertiary destination.
Each and every call will be handled in the same way until the problem is cleared.
