• Interoperability & Protocol Translation
  • Ensures smooth communication between different SIP-based networks and devices.
    
  • Handles protocol conversions, codec translations, and media relay between systems.
    
• Quality of Service (QoS) Management
  • Prioritizes voice traffic to maintain call clarity and prevent jitter or latency issues.
    
  • Monitors call quality metrics and dynamically manages network resources.
