SIPREC Production Readiness Improvements

The following improvements have been made to ensure the SIPREC implementation is production-ready:

Enhanced Validation

  • Added comprehensive SIPREC message validation that checks all required RFC fields
  • Added robust validation of participant information and AOR URIs
  • Added stream validation for mixed streams
  • Implemented validation of state transitions to prevent invalid state changes
  • Added proper role and stream type validation

Improved Error Handling

  • Implemented structured error reporting with error codes and context
  • Added proper error propagation throughout the SIPREC implementation
  • Added specific error responses for different error conditions
  • Enhanced error response to include proper RFC-compliant reason references
  • Implemented validation of critical metadata before processing

Session Management

  • Added proper session tracking with timestamps for creation and updates
  • Implemented session expiration management
  • Added resource cleanup for terminated sessions
  • Enhanced session state change handling with proper validation
  • Added error state tracking to detect and recover from issues

RFC Compliance

  • Added support for RFC 7866 requirements for SIPREC session management
  • Added proper handling of failover scenarios (RFC 7245)
  • Implemented proper MIME formatting for multipart messages
  • Added required participant information in all SIPREC responses
  • Enhanced stream handling for mixed and individual streams

Resource Management

  • Implemented session cleanup for terminated sessions
  • Added tracking of resource usage and proper release
  • Enhanced port allocation and deallocation
  • Added goroutine-based cleanup to prevent blocking on termination

Monitoring and Debugging

  • Added timestamp tracking for debugging session timing issues
  • Enhanced logging for session state changes
  • Added error tracking counters for monitoring session health
  • Added validation warnings to detect potential issues early

Production Metrics

  • Added fields for tracking error rates and retries
  • Added support for logical resource IDs for load balancing
  • Implemented session timeout management
  • Added tracking of source IP addresses for security and diagnostics
  • Added support for callbacks to integrate with external monitoring systems
