Why It’s Different

  • Software based solution can be run on high-end customer hardware/VM to achieve better performance, or in the Cloud (e.g. Amazon AWS) for maximum versatility 
  • Web-based Graphical User Interface provides customer with intuitive, easy access via browser 
  • API’s used (REST, HTTP) enable automated testing using test tools. 
  • Emulated nodes behave exactly as true real nodes, due to Finite State Machine architecture 
  • Testing is scalable across multiple cores and multiple systems



  • Authentication Information requests/answers 
  • Update Location requests/answers 
  • Notify requests/answers 
  • Purge requests/answers 
  • Reset requests/answers 
  • Insert Subscriber Info requests/answers
Configurable Parameters
  • ‍Call session length
  • Concurrent calls/endpoints

Automation API

User commands can be fully automated using REST API. This includes performing all test control functions as well as collecting results and metrics.


The application’s subsystems can be edited directly in the browser using Javascript or by using the graphical tools seen below. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor allows for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
