Integrating Node.js with FreeSWITCH ESL for Call Management and WebSocket Connectivity

1. FreeSWITCH Integration

• Develop a Node.js application capable of handling both inbound and outbound socket connections to FreeSWITCH via Event Socket Library (ESL).

2. Database Design

• Calls Database:
• Store all call-related events and details for auditing, reporting, and monitoring purposes.
• Integrations Database:
• Maintain details about external applications connecting to the Node.js socket, such as:
• WebSocket URLs of external apps.
• Account IDs for integration authentication.
• Routes Collection:
• Define and store call routing rules for managing and directing calls effectively.

3. WebSocket Implementation

• Create a WebSocket service to handle events:
• Outgoing Events: Relay events received from FreeSWITCH to connected external applications.
• Incoming Events: Process events coming from external applications and forward them to FreeSWITCH.

4. Deployment and Containerization

• Dockerize the completed application to ensure a consistent and portable deployment process.
• Deploy the Dockerized application to our servers, ensuring proper configuration and testing in the live environment.

5. Technology Stack

• Backend: Node.js.
• Database: SQL or NoSQL, depending on project requirements and scalability needs.
