About:
Sipsak is a command-line testing tool designed for the SIP protocol, functioning much like a Swiss army knife for VoIP diagnostics. It can generate and send SIP requests such as INVITE, REGISTER, and OPTIONS to test server and client behavior. Its main value is providing a lightweight, scriptable utility for developers and network administrators to troubleshoot SIP connectivity and performance issues.
Key Features:
  • Generates and sends various SIP requests (INVITE, REGISTER, BYE, etc.)
  • Supports SIP over UDP, TCP, and TLS
  • Calculates and verifies SIP message digest authentication
  • Measures response times and latency for performance testing
Use Cases:
  • Verifying SIP server availability and response times
  • Troubleshooting SIP authentication issues
  • Generating load for basic SIP server performance testing
  • Debugging SIP client behavior and message routing
Alternatives:
  • sipp – Sipp is a more complex tool focused on generating high-volume SIP traffic for load testing, whereas sipsak is simpler and better for targeted diagnostics.
  • sipcmd – Sipcmd is a command-line caller that can initiate calls, while sipsak is more focused on sending raw SIP messages for testing purposes.
