Testing Voice

Testing voice requires solutions that cover the technology spectrum from PSTN to VoIP to IMS. These solutions must include test applications for protocol conformance, function and feature validation, and performance testing.

Aptixia IxLoad tests the performance of VoIP networks and devices by emulating SIP and MGCP user agents. IxChariot leads the industry in its ability to emulate real-world applications to predict device and system performance under realistic load conditions. A key IxChariot feature creates sophisticated traffic patterns with and without QoS for IPv4 and IPv6. It measures throughput, jitter, packet loss, and MOS (mean opinion scores) for VoIP. IxVoice is a comprehensive hardware and software framework for testing voice. It provides unified VoIP and PSTN test solutions for the telecom/network equipment manufacturer and carrier and enterprise markets. With its cost-effective, scalable test libraries it addresses all major VoIP protocols: SIP, SCCP (skinny), H.323, MGCP, H.248 (MEGACO), as well as TDM and analog telephony services. Functional, load, and interoperability issues are easily determined using a unique drag-and-drop architecture that instantly creates test scenarios with predefined visual blocks. IxLoad's IPTV over IMS solution validates the key IMS subsystems for interoperability, features, and performance. IxANVL is the industry standard for automated network/protocol validation. IxANVL includes a test suite for SIP conformance, designed to test SIP proxy implementations.
