# Timeout & Retry Escalations

To avoid dropped calls during slow external platform responses, **Asterisk 2** enforces strict socket connection bounds. The communication infrastructure implements customized timeouts and automatic connection fallback circuits.

## Circuit Breaker & Retry Escalation Architecture

The diagram below details the automatic fallback step protecting execution threads during unresponsive API handshakes:

    %% Outbound Query
    subgraph RequestTrigger["Outbound Network Query"]
        ApiCall["HTTP POST /api/validate<br/>(Target External Host)"]
    end

    %% Timer Control
    subgraph ConnectionMonitor["Socket Interruption Engine"]
        CheckTimeout["Verify Request Latency &gt; 3000ms<br/>(Breaches Standard Transport Fences)"]
    end

    %% Retry Path
    subgraph CircuitRetry["Exponential Retry Cluster"]
        ActionRetry["Execute Socket Call Retries<br/>(Max Attempt Cap: 3)"]
    end

    %% Escape Path
    subgraph FallbackRoute["Teardown Escalation Target"]
        DefaultRoute["Trigger AppFlow Escape Path<br/>(Redirect Call to Default Queues)"]
    end

    %% Flows
    ApiCall ==>|"Dispatch Network Frame"| CheckTimeout
    CheckTimeout -->|"Timeout Reached"| ActionRetry
    ActionRetry -->|"Attempt Limits Exceeded"| DefaultRoute

## Connection Resilience properties

### 1. Tight Execution Fences
To completely prevent hung HTTP worker tasks from locking base telephone channels, outbound web actions append programmatic network socket timeouts (`3000ms`). 

### 2. Intelligent Retry Delays
Failed connection states trigger immediate communication attempts using exponential wait sequences (`500ms`, `1000ms`, `2000ms`). If remote host machines remain offline, logical routing pointers advance automatically down default offline flow paths.
