Cyclic Safeguards & Circuit Breakers

To guarantee rock-solid runtime stability across visual dialplans, Asterisk 2 configures strict structural Safety Filters. The runtime evaluates active call paths to clamp infinite evaluation loops and clear deadlocked connections instantly.

Runtime Traversal Loop Interception Map

The layout below traces how runtime token execution pointer steps pass across cyclic boundary safety logic:

    %% Node Entry
    subgraph ExecutionPointer["Active Module Switch"]
        StepEval["Module Jump logic<br/>(Advances Context Token)"]
    end

    %% Loop Validator

        CheckDepth["Verify Session Depth &lt; 50 Jumps<br/>(Validates Traversal Counters)"]
        CheckDupe["Check Recursive Node ID History<br/>(Flags Repeated Cyclic Blocks)"]
    end

    %% Action Routes

        RouteSafe["Continue Traversal<br/>(Trigger Target Module Tasks)"]
        RouteHalt["Clamp Execution Context<br/>(Fires Emergency Teardown)"]

Architectural Circuit Breaker Rules

1. Hard Capped Execution Limits

To completely prevent graphic misconfigurations from dropping worker application kernels into infinite loop states, active call pointers enforce explicit linear evaluation bounds. If a single connected call attempts over 50 unpaused jumps inside a single sequence, evaluating logic execution drops out automatically.

2. Isolated Teardown Trapping

When safety boundaries clamp erroneous call paths, background controllers execute graceful application terminal disconnects (Hangup), clearing physical audio sessions without leaking server memory sockets.
