Detailed Technical Overview

sipsak is a command-line utility for testing and auditing SIP-based Voice over IP (VoIP) applications, proxies, and registrars. It sends customizable SIP requests (OPTIONS, REGISTER, INVITE) to measure round-trip times, perform SIP traceroutes, test registrar authentication, and execute stress tests against PBX endpoints.

Configuration & Usage Guide

To initialize and configure sipsak for telecom security audits, follow these steps:

  1. 1Send SIP OPTIONS ping to target PBX: sipsak -v -s sip:192.168.1.100
  2. 2Execute SIP traceroute to map proxy hops: sipsak -T -s sip:[email protected]
  3. 3Test user registration authentication: sipsak -U -C sip:[email protected] -a password -s sip:192.168.1.100

Troubleshooting & Security Audits

Frequently Asked Questions

What is a SIP traceroute?

Similar to IP traceroute, sipsak increments the Max-Forwards header in SIP OPTIONS requests to discover all intermediate SIP proxies and SBCs in the call path.

Can sipsak generate high-load call tests?

Yes, sipsak can run automated flood and stress tests using the -F flag to measure PBX crash limits.
