For developers of endpoints and IP Phones - a complete unit and feature testing system for H.323 endpoint applications capable of simulating all H.323 components on a network (endpoint, gatekeeper, media and test manager).

For developers of MCUs and gateways - the ability to simulate a vast range of calls using various types of media to validate the quality of applications.

For network equipment vendors and service providers - the ability to simulate calls using various bandwidths and architecture types. ProLab allows you to perform emulations and monitor the network quality before voice and video services are deployed.

For gatekeeper testing - capacity testing for gatekeeper applications

• ProLab H.323 Gatekeeper Simulation provides a full gatekeeper application with possibility to simulate atypical responses according to the standard. Supports registration procedures, address translation services and call control signaling using different modes direct, routed and H.245 routed.
    
• Protocol & Media Analyzer The Protocol & Media Analyzer module carries out advanced analysis and monitoring of all the media streams, including packet loss, jitter, Latency, bandwidth, and RTP Delay. This modules simulates multiple error network conditions, such as packet loss, duplicate packets, delay, and corrupted payload. Monitors the call signaling SIP, SDP and media quality.
   
• Voice Quality is measured by digitized voice lines. MOS is based on the subjective opinions of actual users rating the quality of the voice line on a scale from 1-5.  The model provides measurements based on packet loss, jitter, and round trip delay.
       
• Video Quality The new perceptual Video Quality measurement uses different video metrics. It intrusively analyzes received video streams and perceptually scores relevant degradations on a 5-point MOS scale. Additional key performance indicators (KPIs), like PSNR and blockiness, will be output to allow experts to make a more detailed analysis. Video Quality measurement can be used for IMS, SIP, H.323 and 3G-324M.
