  • Troubleshoot complex voice, call-routing, interoperability, and service-quality issues.  
  • Support VoIP capabilities within the Systems Integration Laboratory and operational gateway environments.  
  • Develop and maintain configuration guides, diagrams, checklists, and technical documentation.
