Socket Transport Declarations

Socket Transport Declarations

To support diverse telecommunication client environments, Asterisk 2 configures dedicated PJSIP transport blocks. The application defines isolated listening structures for clear network layer communications.

Multi-Transport Network Interface Architecture

The flowchart below outlines how incoming socket calls route across dedicated protocol listener handlers:

graph LR
    %% Edge Network
    subgraph IngressTransport["Socket Interface Array"]
        TransUdp["transport-udp Container<br/>(Binds 0.0.0.0:5060)"]
        TransTcp["transport-tcp Container<br/>(Binds 0.0.0.0:5060)"]
        TransTls["transport-tls Container<br/>(Binds 0.0.0.0:5061)"]
    end

    %% Core Proxy
    subgraph AsteriskCore["Ingress Media Router"]
        StasisApp["res_stasis Integration Engine"]
    end

Configuration Parameter Directives

1. Dedicated UDP Sockets (transport-udp)

Optimized for standard LAN hardware connections and local carrier links:

  • protocol: udp
  • bind: 0.0.0.0:5060
  • tos: cs3 (High-priority voice signaling marking)

2. Persistent TCP & TLS Bindings

Enforces reliable delivery across public networks:

  • protocol: tcp / tls
  • cert_file & priv_key_file: References storing validated organizational public/private certificates.
