Background

First of all, what exactly is a Contributor License Agreement (hereafter referred to as CLAas CLA)?

Most Those of us that have who’ve been employed as Software Engineers by corporations are already intimately familiar with CLAswith CLAs, although in the corporate world they are generally called aan “Intellectual Property Assignment Agreement”. In many ways a CLA is a CLA is nothing more than that, but specifically geared towards Open Source projects.

A CLA is A CLA is a legal document in which you state you are entitled to contribute the code/ documentation/ translation to FreePBX and FreePBX and are willing to have it used in distributions and derivative works. This means that should there be any kind of legal issue in the future as to the origins and ownership of any particular piece of code, then FreePBX has FreePBX has the necessary forms on file from the contributor(s) saying they were permitted to make this contribution.

The CLA also The CLA also ensures that once you have provided a contribution, you cannot try to withdraw permission for its use at a later date. People and companies can therefore use that software, confident that they will not be asked to stop using pieces of the code at a later date.

Why

How

The process to record a CLA first requires a GitHub account which is available to all for free. All OSS development at Sangoma is centralized at GitHub. To contribute to the FreePBX project you completely fill out and send in a code submission agreement form. , we ask that you carefully review the text of the agreement by clicking the link here:

Use the button at the bottom to indicate your agreement with the CLA text, which will require that you login using your GitHub credentials. Once done, that GitHub user account can make Pull Requests against all of Sangoma’s OSS projects.

Why

This page was created to maintain a simple way to explain to end users the need for Code Contributor License Agreements and why they are so important. It is key to note that the FreePBX project is not the first to do this and certainly will not be the last. Contributor License Agreements (CLAsCLAs) can be used to enable vendors to easily pursue legal resolution in the case of copyright disputes or to relicense products from which contributions have been received from third parties.

The purpose of a CLA is to ensure that the guardian of a project's outputs has the necessary ownership or grants of rights over all contributions to allow them to distribute under the chosen license. In the case of FreePBX this means that, you, the contributor will assign the copyright in all contributions to the project owner, which is Sangoma Technologies Corp. (who bought the previous company and FreePBX owner Schmoozecom Inc. in 2015). 

Where

If you would like to contribute to FreePBX and are willing to sign the document then you will be able to find it here for download. -

But Foo Project Does Not Require an Agreement!

Just because other projects do not require a CLA does not mean every project besides FreePBX does not require a CLA. In no particular order here is a list of some famous and well known companies that also require a code submission agreement to contribute to their source code.

• Google

• Openstack

• OracleDigium

• Apache Software Foundation

• Bacula, Canonical Ltd

• Chef

• Diaspora

• Digia/Qt Project

• Discourse

• Django

• Dojo Toolkit 

• Eclipse

• Free Software Foundation

• Go

• JBoss Netty

• Joomla

• jQuery

• Meteor

• Node.js

• OpenMediaVault

• OpenStack

• Zend for Zend Framework

Our agreement is very similar to agreements you'd have to fill out if you want to make patches or submit code to any of the companies or projects above.
