Dinstar IP Protocol Integrations

To exchange SIP messages across analog cellular channels, Asterisk 2 configures dedicated handshaking instructions targeting Dinstar hardware arrays. The architecture maps explicit socket channels to individual modem registration ports.

The flowchart below outlines how logical call requests translate down into physical modem array assignments:

    %% Outbound Request
    subgraph RequestSource["PBX Application Logic"]
        TargetCall["Outbound Route Dial<br/>(Target Number String)"]
    end

    %% Dispatch Node
    subgraph LoadBalancer["Kamailio Core Bridge"]
        SelectPort["Select Active Gateway Interface<br/>(Matches Pool IP Address)"]
    end

    %% Target Hardware Ports
    subgraph DinstarRacks["Physical Modem Modules"]

        PortB["Modem Port 1<br/>(Binds Local Interface 5064)"]
    end

Technical Handshaking Configurations

1. Independent Port Mapping Strings

Every GSM module card presents an isolated SIP identity registration over discrete port increments:

Port 0: 5062
Port 1: 5064
Port 2: 5066

2. Echo Cancellation Calibration

Hardware profiles implement strict non-linear echo processing (echocancel=yes) directly at the Dinstar DSP level. This scrubs analog reflection noises completely prior to delivering digital audio streams back to PBX listening blocks.

## Technical Handshaking Configurations

### 1. Independent Port Mapping Strings
Every GSM module card presents an isolated SIP identity registration over discrete port increments:
- **Port 0**: `5062`
- **Port 1**: `5064`
- **Port 2**: `5066`

### 2. Echo Cancellation Calibration
Hardware profiles implement strict non-linear echo processing (`echocancel=yes`) directly at the Dinstar DSP level. This scrubs analog reflection noises completely prior to delivering digital audio streams back to PBX listening blocks.
