The 323Sim is an H.323 simulator of traffic load, and a call generator (VoIP) that enables developers and service providers to benchmark, load test and verify proper protocol implementation in VoIP equipment under heavy stress. Focused on protocol flexibility, the 323Sim can stress every type and aspect of any network entity implementing the H.323 protocol. The 323SIM is an H.323 load test tool aimed at H.323 simulation and H.323 stress tests. The tool provides massive H.323 traffic generation and H.323 simulation aimed at testing various protocol applications, services and network elements. Main Advantages - Generates up to 6000 simultaneous calls per server with unlimited scalability
- Sends and receives H.323 voice and video calls and interacts with other H.323 entities
- Simulates several different load traffic profiles: Ramp, Poisson and Normal Distribution
- Provides fine-grain control over call setup rates and parameters
- Displays call activity and completion statistics such as setups, releases, active calls online and GoS
- Transmits RTP packets (encoded in various Codec formats) for gateway load testing
- Supports H.261, H.263 and MPEG-4 video streams
- Tests DTMF integrity
- Enables activation of specific portions of the call setup process (RAS, Q.931 or H.245) for pinpoint testing
- Supports fast start connections and early H.245
- Supports tunneling mode H.245 using H.225 signaling
- Supports objective voice quality measurement in collaboration with other Performer components
- Enables RTP generation using the copper 10/100/1000 Mbps Line Interface Module
- Provides automation capabilities through MasterScript, a powerful scripting tool
- Supports many Codec types
- Supports alternate gatekeepers
- Tests integrity of gatekeeper communication procedures under stress by enabling RAS message generation
