SS7 QPro Adds End-to-End SS7 to IP Testing to VoIP Performer(TM)

RADCOM Ltd. (NASDAQ: RDCM), a leading network test and quality management solutions provider, today announced the addition of SS7 stress testing to its call quality measurement solution suite.

The SS7 QPro is an SS7 (Common Channel Signaling System No. 7) protocol simulator that generates high volume Public Switched Telephone Network (PSTN) calls, enabling customers to stress test convergence devices that bridge traditional telephone and fast-growing packet-switched networks.

RADCOM's SS7 QPro simulates a Service Switch Point (SSP) that can connect to other SSPs, Signaling Transfer Points (STPs), and multi-technology signaling or media gateways. Using Ramps, Poisson or Normal traffic modules, vendors and service providers can use the SS7 QPro to generate test traffic and measure call quality and network performance in varied, simulated environments.

The SS7 QPro supports up to 16 links and up to 10 E1/T1 voice and signaling ports. It is the latest addition to RADCOM's VoIP Performer suite, which includes high-volume VoIP call generation, voice and signaling analyses, protocol decoding and WAN impairment simulation.

"We are pleased to announce the successful completion of final acceptance testing and the subsequent purchase of the SS7 QPro by Ericsson. The multiple unit purchase comprises additional VoIP Performer elements including the SIPSim and the NetSim, providing Ericsson with circuit and packet call generation as well as WAN impairment emulation capabilities," said David Ripstein, RADCOM's General Manager of Products and Technologies. "By continuing to expand our offering of integrated hardware and software solutions controlled from an easy-to-use console, RADCOM offers customers the advantage of partnering with a single-source vendor committed to meeting their wide-ranging, convergence testing needs."
