VoIP Load Tester

The Valid8 VoIP Load Tester solution is capable of simulating and testing Endpoints (Audio and Video), Proxies, SBCs, Gateways, UACs and more. It is a top tier real-world device simulator, which supports popular vendor modes and profiles.

Description

H.323 and SIP are standards that define the protocols for audio-visual communication sessions over IP. They are both widely implemented by voice and videoconferencing equipment manufacturers.

The Valid8 VoIP Load Tester allows you to test Endpoints, PBXs Gateways, and test load and feature interaction for audio and video. It enables continuous route testing through the network to report quality and find issues. It is useful for small and large carriers: ILECs, CLECs, ASPs, ISPs, as well as enterprise customers. It automates deterministic verification of routes and phone numbers across VoIP networks, saving time and increasing effectiveness and coverage of testing. Rules are set up in the tool to cycle through multiple network destinations and phone numbers according to the test plan.

Features of our VoIP Load Tester

  • Real-world device simulation supporting popular vendor modes and profiles
  • Simultaneous SIP and H.323, WebRTC, H.264 and H.263, VP8, G.7xx, OPUS
  • Measure Key Performance Indicators (KPIs) such as number of simultaneous sessions and Busy Hour Call Attempts (BHCA)
  • Tests up to 5,000 sessions (calls) in parallel per core (scalable)
  • ICE/TURN/STUN
  • DTLS/SDES
  • Custom REST/HTTP/JSON signaling
  • Check dialing in/out of HD video systems
  • Supports dialing through IVR using DTMF prior to activating video and audio playback
  • Report on media received, call connect time,call duration, jitter, packet loss to check SLAs are being met
  • Alerts and notifications
  • Check parameters in messages from SUT and flag errors
  • Generate valid and invalid/negative messages and call-scenarios, including malformed, dropped and misordered packets
  • Continuously test routes and cycle through destinations across VoIP networks and call numbers according to configurable rules
  • Check billing accuracy in conjunction with Radius/Diameter (optional)

What can it do?

The VoIP Load Tester is capable of simulating and testing several devices individually or in parallel. It can simulate WebRTC clients and test SBCs, ESBCs, proxies, and endpoints.
