Dynamic Outbound Gateway Pools

To route external telecommunications traffic optimally, Asterisk 2 groups physical gateway hardware assets into logical mapping collections called Gateway Pools. This database module maps out available cellular hardware arrays to balance session assignments cleanly.

Gateway Load-Balancing Schema

The diagram below outlines how logical pools sort outbound traffic assignments dynamically across raw physical IP addresses:

graph LR
    %% Logical Pool
    subgraph LogicalPool["Logical Outbound Mapping"]
        EntityPool["GatewayPool Entity<br/>(PK: PoolId, Name: 'Indian Mobile Trunks')"]
    end

    %% Target Elements
    subgraph TargetMembers["Assigned Physical Gateways"]
        MemberA["GatewayMember Entity<br/>(IP: 192.168.10.50, Weight: 100)"]
        MemberB["GatewayMember Entity<br/>(IP: 192.168.10.51, Weight: 50)"]
    end

    %% Downstream Logic
    subgraph ExecutionTarget["PBX Outbound Core"]
        KamailioDisp["Kamailio Dispatcher Target<br/>(ds_select_dst Engine)"]
    end

    %% Vectors
    EntityPool ==>|"Includes Mapping"| MemberA
    EntityPool ==>|"Includes Mapping"| MemberB
    MemberA ==>|"Primary Selection"| KamailioDisp
    MemberB -->|"Secondary / Failover"| KamailioDisp

Model Attribute Blueprint

1. GatewayPool Entity

• PoolId (int): Primary automatic auto-increment integer ID.
• PoolName (string): Logical descriptor mapped to specific dialing groups.
• Members: Collection mapping physical gateway IP references.

2. GatewayMember Entity

• MemberId (int): Primary automatic auto-increment integer ID.
• PoolId (int): Foreign key connecting the hardware node to its parent logical pool.
• IpAddress (string): Network address string mapping directly to physical Dinstar rack interfaces.
• Weight (int): Numerical value determining priority dispatch selection frequency during round-robin distributions.
