Fax communication remains critical in many industries, and Faxage, combined with the robust infrastructure of AWS technologies, enables seamless, modern, and reliable fax management. This blog highlights how we use Amazon Web Services (AWS) to build a scalable and automated fax solution that ensures efficiency and accuracy, making it an attractive option for businesses looking to modernize their workflows.

1. Sending Faxes with AWS and Faxage

Our solution integrates AWS services with Faxage to streamline the process of sending faxes. Leveraging AWS Lambda, API Gateway, and Amazon S3, the system ensures automation and security.

1.1 How It Works

  1. Uploading Files: Files to be faxed are stored securely in Amazon S3.
  2. Triggering Fax Sending: A Lambda function reads the file from S3 and interacts with the Faxage API to initiate the fax process.
  3. Tracking with Context ID: Each fax is tagged with a Context ID, a unique identifier that links related communications for easy tracking.

1.2 Real-Time Status Updates

The fax-sending process is asynchronous. Using API Gateway, the system returns a job ID that is tracked by a Lambda function, which regularly checks the Faxage API for updates. The status is logged in a DynamoDB table and synced with a connected record system for end-user visibility.

1.3 Technologies Used

  • AWS Lambda: Manages the logic for interacting with Faxage.
  • Amazon S3: Securely stores files to be faxed.
  • Amazon API Gateway: Provides a secure and scalable API for initiating fax operations.
  • Amazon DynamoDB: Stores job statuses and fax metadata for quick retrieval.

2. Secure and Scalable API Integration

2.1 Generating Access Tokens with AWS Cognito

Access tokens required for API usage are generated through AWS Cognito, ensuring secure user authentication and authorization. This eliminates the need for static credentials, reducing security risks.

2.2 Sending Faxes

With a valid access token, users can send faxes using an HTTP POST request through Amazon API Gateway, which routes the request to a Lambda function. This function reads S3 objects and communicates with the Faxage API to send the fax.

2.3 Benefits

  • Security: Tokens generated by AWS Cognito provide strong authentication.
  • Scalability: Amazon API Gateway and AWS Lambda ensure the system scales with demand.
  • Reliability: Amazon S3 and DynamoDB provide robust storage and data handling.

3. Receiving and Processing Faxes with AWS

Our system automates fax receiving and processing, using AWS SQS, Amazon Textract, and other AWS services to handle large volumes of incoming faxes efficiently.

3.1 Receiving Faxes

  1. Fax Retrieval: A Lambda function retrieves unprocessed faxes from the Faxage API and stores them in an Amazon S3 bucket.
  2. Queue Management: New faxes are added to an SQS queue for further processing.

3.2 Advanced Processing

  • Text Extraction: Using Amazon Textract, the system extracts key details like Context ID and detects signatures from the received fax.
  • Status Updates: Fax statuses are updated in DynamoDB and synchronized with the connected record system for user access.

3.3 Cleanup and Finalization

A Lambda function marks processed faxes as "handled" on Faxage and updates their status in DynamoDB, ensuring the workflow remains organized.

4. Key AWS Technologies in Use

  • Amazon S3: Secure file storage for both outgoing and incoming faxes.
  • AWS Lambda: Serverless functions to handle fax logic, file processing, and API communication.
  • Amazon API Gateway: Secure API endpoints for initiating fax operations.
  • AWS Cognito: User authentication and token management for secure access.
  • Amazon DynamoDB: Scalable NoSQL database for storing fax metadata and statuses.
  • Amazon SQS: Message queue for managing asynchronous tasks, like downloading and processing faxes.
  • Amazon Textract: Automated document analysis for extracting text and signatures from received faxes.

5. Advanced Features: AI-Driven Processing

5.1 Context ID Extraction

Using Amazon Textract, the system scans documents for Context IDs and links them to ongoing communication threads. This improves traceability and operational efficiency.

5.2 Signature Detection

The system uses Textract to analyze received faxes for signatures, enhancing document validation and compliance.

5.3 Asynchronous Processing

AWS’s serverless architecture ensures that tasks like text extraction and signature detection are handled efficiently, without bottlenecks, even during peak loads.
