Solver for ISUP is a high-performance load and stress test tool for ISUP based telecommunication networks. Solver provides the ability to simulate ISUP calls with a large number of simulated subscribers providing load to switches.

Solver ISUP can simulate a Public Switched Telephone Network (PSTN) with hundreds of thousands connected subscribers providing load to the Core Network (CN). A number of different traffic scenarios and various call settings can be made in order to achieve as close to real-life traffic conditions as possible.

Solver makes it possible to generate and terminate calls, test network indicators and provide real-time statistics on traffic progress. Various traffic patterns are easily created to run simultaneously or in sequence.

• Originate and terminate calls with Control Plane signaling and User Plane (payload).
• Provides fine-grain control over call set-up rates and parameters.
• Displays call activity and completion statistics such as set-ups, releases and active calls on-line.
• Generates high traffic load towards the Core Network.
