This VoIP monitoring tool can simulate and monitor thousands of SIP calls with RTP media, enabling users to test the network, software, and hardware. It provides real-time quality analysis for call monitoring.

One of its most impressive features is the Freeware unlimited non-intrusive monitoring of existing VoIP deployment, capturing, and analyzing SIP/RTP packets with real-time reports and charts, which is a passive testing. Its high-performance functionality, including scalable distributed architecture with SIP and RTP modules modularly installed in one or many PCs, makes it possible for one i7 server to simulate 5400 simultaneous G.729 calls or 2600 G.711 calls.
The software further comes with additional features like Audio verification; identification of IVR messages, conference testing, real-time analysis of voice quality for all RTP streams, calculation of global min MOS, global max jitter, and many more. With the lowest quality calls report, it's easy to see the worst call in a test, while its support of RTP header extensions for ED-137 air traffic management (ATM) VoIP tests, and Measurement of round-trip delay, and VoIP recording makes it highly versatile.
The SIP Tester can be used in several scenarios. For instance, it's useful in performance and stability load testing of SIP servers and IP networks, testing of memory leaks with millions of calls, and testing of IVR servers, PBX, call centers, and other applications when upgrading to a new version or moving to a new SIP platform. Its ability to monitor VoIP quality of existing IP networks and servers, generating alerts and reports about system performance, makes it highly advantageous.
You can use the software to test and monitor SIP-GSM, SIP-PSTN gateways, SIP trunks, and do 24x7 monitoring of RTP jitter and VoIP infrastructure availability. In summary, the SIP Tester is a highly versatile software that provides unparalleled VoIP load and stress testing, monitoring functionality, with several use cases in diverse scenarios.
