IxLoad — Voice Test Solution

Validate that your voice service delivers a high quality of customer experience

Problem: Maintaining Voice Quality in the Face of Exponential Traffic Increase

Voice delivery over convergent networks has its own challenges, as quality of experience (QoE) is strongly affected by latency and jitter. Measuring real-world call-flow characteristics to quantify how ever- changing traffic patterns affect voice is critical to the success of deploying voice communication solutions. Regardless if the solution is voice over LTE (VoLTE), unified communication (UC), call center, telepresence, or just regular voice over IP (VoIP), service providers and enterprises must meet consumer QoE expectations.

Solution: Comprehensive Testing for Voice Delivery Platforms

Ixia’s IxLoad is the industry’s most scalable and flexible solution for realistic load testing of VoIP platforms to validate end-to-end voice delivery architectures. It emulates thousands of user sessions with dynamic call flows and measures real-time voice quality.

Highlights

 • Ensure voice delivery systems perform at peak loads and conform to interoperability standards

• Reduce post-deployment issues and customer churn by validating QoE using in-depth SIP and media analysis, including subjective quality of voice (POLQA / PESQ)

• Quickly detect and pinpoint performance issues by emulating complex, real world, multiplay multi-subscriber environments

• Reduce learning curve with library of pre-built test cases and intuitive drag-and-drop GUI

• Increase productivity with embedded intelligent state machine that automatically handles test details so test engineers can focus on the features under test

Key Features

• Emulate real-world traffic using Ixia’s highly scalable test platform or virtual ports

• Simulate detailed call control state machines, messages, and contents and create any test case, including negative testing

• Integrate with the real-time transport protocol (RTP) test library to generate voice, conversational video, and tones, and use a multitude of voice and video codecs to measure voice or video quality

• Fully automate feature and regression testing using the IxLoad TCL, REST, Python or Perl API

Product Capabilities

Voice and conversational video quality assessment

IxLoad Voice is the perfect tool for functional, performance, and stability testing of SIP-based VoIP network components. Because IxLoad supports SIP, SDP, MGCP, H.248, SKINNY, and RTP protocols with voice codecs, video telephony, and fax in addition to video and data protocols, it can be used to test a variety of network components in VoIP, IMS, VoLTE and UC topologies.

IxLoad provides IMS system and sub-system developers and providers with a complete solution to verify all aspect of IMS systems and their components. IxLoad is an invaluable tool for service providers and network equipment manufacturers (NEMs) for functional, protocol, conformance, regression and performance testing of end-to-end IMS networks and individual components. A single test can be used for both functional and load testing, on a single hardware platform.
