SIP End-to-End Testing

publish to docker hub

SEET is a suite for end-to-end testing of SIP deployments. We aim to add useful artifacts to help test and troubleshoot any SIP device or software. SEET is inspired in pysipp.

It lets you run complex scenarios involving multiple UASs and UACs. With SEET, you create your SIPp XML scenarios as usual and the suite creates the necesary User Agents and ensure the scenarios run in the correct sequence.

Example of scenario file

    "name": "Simple SIP Message",
    "description": "UAC sends a simple MESSAGE to UAS and waits for an OK response",
    "target": "",
    "transportMode": "u1",
    "domain": "sip.local",
    "userAgents": [
        "mode": "uas",
        "scenarioFile": "scenarios/ims_uas.xml",
        "authentication": {
          "username": "1001",
          "secret": "1234"
        "sendRegister": true,

Available Versions

You can see all images available to pull from Docker Hub via the Tags page. Docker tag names that begin with a "change type" word, such as task, bug, or feature, are available for testing and may be removed at any time.


You can clone this repository and manually build it.

git clone https://github.com/fonoster/seet
cd seet
docker build -t fonoster/seet:%%VERSION%% .

Otherwise, you can pull this image from the docker index.

docker pull fonoster/seet:%%VERSION%%

Usage Example

The following is a basic example of using this image. Be sure to add the port of every User Agent Server. If you use an udp mode in your scenario (e.g. u1), you must also bind the port in docker with the corresponding notation.

docker run \
  -v $(pwd)/seet.json:/seet.json \
  -v $(pwd)/scenarios:/scenarios \
  -p 7060:7060/udp \
  -t fonoster/seet 

or with NodeJS

# Requires of sipp 3.6.0-r2 installed in the host
npm i -g @fonoster/seet
SCENARIOS=$(pwd)/seet_example.json seet

Environment Variables

Environment variables are used in the entry point script to render configuration templates. You can specify the values of these variables during docker run, docker-compose up, or in Kubernetes manifests in the env array.

  • SCENARIOS - Changes the default path to the scenario file.

Exposed ports



  • /scenarios - Location for your SIPp XML files
  • /seet.json - Default location for your scenarios file
