OASIS is a highly modular product enabling components to be delivered and integrated into an existing emergency call handling infrastructure. OASIS can also be implemented into a greenfield site approach to cover the majority of needs. OASIS meets the key functional requirements for emergency call handling by providing: 

• Highly efficient queue management.
  
  
• High platform availability to ensure optimum uptime and with no single points of failure.
  
  
• Resilience in the form of multiple layers of redundancy ensuring systems can continue to function during major disaster scenarios.
  
  
• Specialised call routing to ensure calls are not relinquished in error and with complete call control to manage the calls throughout their life.
  
  
• Flexible integration framework to interconnect to supporting databases and systems
  
  
• Specific emergency database provision.
  
  
• Integration to mobile location information services for mobile subscribers, such as the LIF – Location Information Forum.
  
  
• 100% call recording of all emergency calls for audit and quality control, together with agent desktop recording for a complete understanding of each recorded call.
  
  
• Silent call management, whereby calls made in error can be managed and if necessary forwarded to an automated system.
  
  
• Accessibility with support for text phones, for example, to ensure services are accessible for deaf people.
