GL Communications, Inc. recently announced the launch of its product PacketH323 – H.323 Single Call Generator Software. GL Communications (News - Alert) supplies PC-based test, analysis and simulation products and consulting services to the international telecommunications industry.

“Voice transmission over packet networks continue to present challenging quality of service issues – including echo, delay, voice clipping and impairments due to lost or jittered packets,” said Jagdish Vadalia, Senior Manager at GL Comm. “These problems are exacerbated even further during high degrees of voice compression. Adequate tools for generating characterizing and measuring impairments are not readily available. GL's PacketH323 fills this void with a set of tools for simulating H.323 calls and generating real-time traffic on VoIP networks.”

Key features of the PacketH323 include Voice Quality Measurements (PAMS, PSQM, PSQM+, PESQ MOS and PESQ LQ); Real-time talk and playback (using microphone/speakers attached to PC); Full H.323 Functionality; Manual and Automated Calling capabilities; Fully Remote Controllable; Send/Detect User-defined frequency tones; Send/Detect DTMF/MF digits (both in-band and out-band); Audio Codecs including G.711, G.726 and G.729A/B; and access to H.323 messaging parameters.

“PacketH323 is a PC-based real-time VoIP call generator for providing voice band testing over the H.323 VoIP Protocol,” Vadalia continued. “It can generate single calls, either manually or in an automated fashion, and generate an array of traffic once the call session is established. Call Records, Call Statistics and Protocol Events are all captured and displayed to the user in real time.”

“PacketH323 is fully Client/Server enabled; thus the user can control it from a remote location either within a Client GUI or a Client Command Line (supports scripting applications),” Vadalia added. “An optional hardware RTP can support real-time voice calls from analog phones, or fax calls from fax machines.”

GL’s TDM Analysis & Emulation suite of products include the T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire, analog two-wire interface cards and external portable pods.
