Overview
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. 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.
PacketH323™ is a PC-based real-time VoIP call generator for providing voice band testing over the H.323 VoIP Protocol.
PacketH323™ 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, Protocol Events are all captured and displayed to the user in real time.
PacketH323™ is fully Client/Server enabled, thus, the user can control PacketH323™ from a remote location
either within a Client GUI or a Client Command Line (supports scripting applications). An optional hardware RTP can support real-time voice
calls from analog phones, or fax calls from fax machines.
Features:
- Full H.323 Functionality
- Manual and Automated Calling capabilities
- Fully Remote Controllable
- Real-time talk and playback (using microphone/speakers attached to PC)
- Voice Quality Measurements (PAMS, PSQM, PSQM+, PESQ MOS and PESQ LQ)
- Send/Detect User-defined frequency tones.
- Send/Detect DTMF/MF digits (both in-band and out-band).
- Audio Codecs supported include G.711, G.726 and G.729A/B
- Access to H.323 messaging parameters
Manual and Auto Call Generation
PacketH323™ supports both Manual and Auto Call Generation, with complete flexibility on the call session. Configure
call duration, inter-call duration and type of traffic (both send and receive) desired.
- Current Status of each configured session
- Traffic Generation and QOS measurements
- Real-time talk and playback

PacketH323™ Traffic Generation
Once the call is established, PacketH323™ can generate a multitude of traffic, either manually or automatically. This
traffic includes Voice, Frequency Tones (single and dual) and DTMF/MF digits. The PacketH323™ also provides the capability
to record voice and detect Frequency Tones and DTMF/MF digits. Send and record voice simultaneously in order to provide end-to-end
delay results. PacketH323™ also provides the necessary Voice Quality algorithms, thus providing the ITU standard PAMS,
PSQM, PESQ MOS scores.
