IxLoad Voice SIP Key Features

IxLoad Voice SIP Key Features IxLoad Voice SIP is the perfect tool for functional, performance, and stability testing of SIP-based voice over IP (VoIP) network components. Because IxLoad supports SIP, SDP, H.323, 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, including: SIP proxies and Registrar servers Media gateways Call agents Session border controllers (SBCs) and Application Layer Gateways Multiplay delivery networks EPC and IMS core in VoLTE configurations IxLoad in a typical configuration simulating SIP endpoints and SIP Proxy to test a distributed Application Layer Gateway (ALG) Emulates real-world traffic using Ixia s highly scalable test platform Simultaneously supports data, voice, and video protocols to emulate a multiplay subscriber environment Simulates SIP endpoints and SIP endpoints behind one or many SIP Proxies Simulates SIP Proxy and SIP Registrar server Maintains full control over SIP state machines, messages, and contents. Allows the creation of any test case, including negative testing. Drag and drop GUI permits functional building blocks to be easily assembled into test cases and call flows with automatic protocol rule enforcement The session timers and message retransmission mechanisms are present with the option to be disabled by the user When in SIP Proxy mode, the module routes the SIP messages based on content of the SIP messages following the user defined rules Graceful stop at ramp-down to end all the active calls at the end of test Test cases built for functional and feature testing can be reused for stress testing 26601 Agoura Road Calabasas, CA 91302 USA Tel + 1-818-871-1800 www.ixiacom.com Document No.: 915-1726-01 Rev J August 2015 - Page 1
