## What it is
SIPp is a free, open-source SIP (Session Initiation Protocol) protocol testing tool written in C++. It can generate SIP traffic to test, benchmark, and load-test SIP proxies, PBXs, and other VoIP infrastructure.

## Use cases
- load test a SIP proxy with thousands of concurrent calls
- emulate SIP user agents for regression testing a PBX
- benchmark VoIP infrastructure call setup rates
- replay PCAP media during SIP call scenarios
- test SIP-over-TLS and SIPS traffic with Wireshark decryption
- simulate SIP endpoints in CI pipelines

## When to choose
- you need a mature, scriptable SIP traffic generator and load tester
- you want to emulate SIP UAC/UAS behavior with custom XML scenarios
- you need protocol-level SIP testing without a full softphone

## When to avoid
- you need functional UI-driven VoIP calls rather than protocol testing
- your target protocol is not SIP (e.g., WebRTC signaling alone)
- you need a graphical test suite with no CLI/XML scenario authoring

## Facets
- artifact type: cli-tool
- maturity: active
- function: testing, benchmarking, load-testing
- domain: developer-tools, testing
- platform: windows, cli
- tags: sip, voip, protocol-testing, traffic-generator, telephony, telecommunications, linux, macos, docker
