11.1.6.2.2. Service Information 
- Overflow after timeout is not executed for directed calls to an Attendant (serial call, re-call, personal call etc.). Exception: this Attendant is pre-blocked or is unplugged.
- The priority level is newly calculated at the overflow Attendant. For the internal and external first calls (incl. intercept), as well as for priorized stations, the priority numbers of the configured overflow call types apply.
- Every Attendant group has its own overflow destination.
- The overflow is active if an AC group has been specified as overflow destination.
- The over–running time is centrally adjustable.
