NGN Load Tester


The Valid8 NGN tester enables testing of SIP, ISUP, Megaco and RTP.

What It Can Do For You

Tests endpoints, SSE, DHCP server, media gateway, CO switch

Why It’s Different

  • Scalable software-based architecture can run on a range of hardware from COTS and high-end customer provided hardware to Virtual Machines and the Cloud (e.g. Amazon AWS) for maximum versatility and performance
  • Web-based UI is easy to learn
  • HTTP API enable integration with automation test systems and other equipment
  • Stateful modeling provides accurate emulation of network elements


  • Measure Key Performance Indicators (KPIs) such as number of simultaneous sessions and Busy Hour Call Attempts (BHCA) 
  • Check voice, video calls 
  • Registration load 
  • RTP media file playback 
  • Report on media received, call connect time, call duration, jitter, packet loss 
  • Generate valid and invalid/negative messages and call-scenarios 
  • Supports sending invalid responses including malformed, dropped and misordered packets 
  • Alerts and notifications


  • Call Attempts 
  • Call Successes 
  • Call Failures 
  • Calls per second (CPS) 
  • Call setup time 
  • Call tear down time 
  • Media Tx Packets (audio) 
  • Media Rx Packets (audio) 
  • MOS/PESQ score * optional
Configurable Parameters
  • ‍Call session length
  • Concurrent calls/endpoints

Automation API

User commands can be fully automated using HTTP 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 TDL or by using the graphical tools. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor (on the feature roadmap for 2019) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.

Use Cases

SIP Server Under Test

For testing the SIP Server, the Valid8 Tester can generate SIP calls to test performance and stability.

Supported Scenarios:

Message flows

  • INVITE Audio/Video calls
  • INFO

Emulate Real Network Conditions

  • Peak times
  • PSTN to IP calls
  • Jitter
  • Limited bandwidth
  • Duplicate packets
  • Corrupted packets
  • Bursty network traffic
  • Redundant link switchover / outage

Media Gateway Under Test

For testing the Media Gateway (MG), the Valid8 Tester can generate SIP, Megaco & ISUP calls with user plan media to test performance and stability.

Supported Scenarios:
  • SIP calls
  • Megaco calls
  • ISUP calls
  • TDM user plane
  • Voice Quality
