FreePBX is a true Open Source development effort. Providing GNU GPL v2, GPL v3 or AGPL v3.0 (or equivalent) licensing is all that is required to make a project Open Source. However, obtaining true community involvement is what makes a good project become great. This means transparent access to the project's activities and a development community with access to the project that is not limited to a sponsoring organization. These values are what fuel a really successful project.
The FreePBX Project uses the Atlassian JIRA (Issue Tracker) and Atlassian Bitbucket (Version Control System) applications in order to tightly integrate the GIT Activity, Ticket system and Development Wiki. We have integrated this system with our main site (freepbx.org) so that you are able to sign on to both sites when you create an account (https://www.freepbx.org/user/register). Without an account, you will not be able to submit tickets but you will still have access to all development tools and viewing privileges
To participate in the FreePBX project you must agree and submit a filled out copy of our code submission agreement: http://literature.schmoozecom.com/EUA/CodeSubmissionsAgreement.pdf (For more information on this Please see our FAQ). This is only required to submit code back to the FreePBX project
Please take a look at our development documentation for setting up a development environment here: Setting Up a Development Environment
Code quality is very important when it comes to things such as security, maintainability. PHP tends to get a bad rap because it allows bad behavior. Just because you can do something doesn't make it the right thing. The following 3rd party links discuss quality coding practices. These guidelines can help both new and seasoned programmers when developing for FreePBX.
You can take a quick look at our source code:
Community Design and Development
In addition to taking input and feedback from the community at large, FreePBX tries to keep its design and road map plans transparent and accessible. This means ideas are discussed in the Forum, in the Wiki and in the #freepbx-dev IRC channel. Live interaction can also be extremely beneficial, so many phone conversations do take place (after all we are all about phones...). We try hard to document the content of these conversations into the Wiki to further benefit from community review and input.
Project roadmaps are provided on this wiki under: Roadmap
The easiest way to get started is to simply take a look at our bug tracker. We have overcurrently open for FreePBX alone.
The wiki lists many ways to get involved. If you want to develop for FreePBX a good way to start is to contact one of the active developers. You can message them on https://community.freepbx.org them, or you can get onto the Development IRC channel #freepbx-dev on Freenode and make contact.
If you'd like to jump in and get your hands dirty by creating your own FreePBX module you can do so by utilizing our FreePBX Module Generator.
We also have a couple of php example modules you might find of interest.

|FreePBX Hello World Module||13+||https://github.com/jfinstrom/helloworld|

To assist in bug fixes and improvements you may fork one of the sub modules on Github at https://github.com/FreePBX/ or https://github.com/FreePBX-ContributedModules. Once you have your code tested and working you can submit a pull request or submit a patch after you have fully completed our CSA on file. All bug fixes and feature requests should relate to a ticket at http://issues.freepbx.org. If you have written a module you would like included in our contributed repo (https://github.com/FreePBX-ContributedModules) simply create a repo for your module on Github then open a ticket in the bug tracker to make us aware of it and we can mirror your repo. Remember all code submissions through the bug tracker or through git require a CSA on file. If you are new to GIT please see our wiki for a general overview.
We have also created a tag in our issue tracker called "patches welcome" for items that seem like solid ideas but we do not have official resources for. A good place to get your feet wet may be in working on one of these issues. Our "Patched Welcome" issues are listed below.
Beyond code development there are many ways that you can help. Translations are important and you do not need to be a developer to help in this area. For information on translating go here.
The more quality documentation that exists in a project, the more useful and valuable it becomes. This includes creating original content whether it be How-To Guides, Module Documentation or other forms. It also includes editing existing documentation for correctness and completeness and helping to get the site into a more standardized and organized form. If you have expertise in this area and would like to help drive it, please contact us.
Development Documentation is critical as well. If you are a developer, you probably know that this can be a weak point for many. There is a lot of information on the Development Wiki but it is also a priority of ours to put some effort into cleaning and updating the documentation, organizing it and augmenting it to make it easier for new developers to get involved.
New module submissions are a regularly occurring event and you will find many modules that have been submitted as tarballs in the Ticket system that are not available in the online system. Why is that?
The FreePBX project is designed as a Framework that can easily accommodate new modules and for that reason, new modules get written and submitted. This does not mean that we put every module that comes along into the project. As the project has matured and stabilized, we are putting a lot more thought into the architecting of the FreePBX as it continues to evolve and mature into a world class product. In order to do that, we need to carefully evaluate what officially enters the system since adopting a module has many implications. We try very hard once something becomes part of the project to take on the commitment of maintaining and supporting it and making sure that future upgrades of the project will continue to work with the Modules that are part of it. If you are thinking about writing a module that you would like to be part of the core project, you should talk with one of the active developers in advance.
This does not mean that the other modules are less valuable or inferior in any way, if we don't adopt them. If you have written a module you would like included in our contributed repo simply create a repo for your module on github. Open a ticket in the bug tracker to make us aware of it and we can mirror your repo. Remember all code submissions through the bug tracker or through git require a CSA on file.
