Detailed Explanation     Restcomm™, the most popular open source projects on the market for developing real time communications applications, is available under two licensing agreements. The table above provides a quick view of the major differences between the two license agreements. Below is an explanation for each of the items compared within the table.    Many of the items listed in this document are called out specifically in either the AGPLv3 license available at http://www.gnu.org/licenses/agpl-3.0.html or the Telestax© Restcomm™ Subscription Agreement available here.     

Contribute source code modifications back to the community

Open Source AGPLv3

Telestax Subscription

Yes

No

   Open Source AGPLv3 license  As a starting point it is important to understand two key differences between the two licenses. First, any organization deploying Open Source Restcomm as a part of their offering must acknowledge their use of Restcomm within their product or on their website. The second key difference is how modifications to the source code are treated. In the AGPLv3 license, any modification to the open source code must be immediately shared within the community. Each organization that modifies the Open Source Restcomm code must share what they have created. This requirement is why there is a web of forks in the open source Restcomm code because every company will share the source code inclusive of their modifications.     Telestax Subscription license   Telestax Subscription license relaxes the requirement to contribute changes back to the community. Many organizations that have added enhancements to Restcomm open source by modifying the code may not want to offer them back to the community. Doing so could neutralize their competitive advantage and make their offering weak. This is a strong argument for upgrading to a Telestax Restcomm subscription license. The subscription license relaxes the mandate for sharing modifications made to the Restcomm open source code, allowing their competitive advantage to remain confidential.

Cleanliness of code line

Open Source AGPLv3

Telestax Subscription

Many forks – release early and often

Single stable code line – fixed release cycles

  Open Source AGPLv3 license  When an organization wishes to extend Open Source Restcomm to suit their purpose, they add their modification(s) to the source code, which then creates a new version of the code line (Restcomm source code plus modifications). This is what is called forking the code. For every project that produces modifications to the source code, a fork is generated. Based on this process, it is easy to understand that there will exist hundreds of forked code lines for open source Restcomm. Further in the spirit of open source, releasing code lines often and asking the community perform QA in real time could affect the stability of a given Restcomm fork.    Telestax Subscription License  Telestax performs the exact same process with Restcomm Enterprise that is associated with any enterprise-class software product. Telestax maintains a single stable code line with fixed release cycles. Features that go into release cycles are influenced in two ways. First, Telestax monitors all Open Source Restcomm forks and selects the best and most stable features to incorporate into Restcomm Enterprise. Second Telestax pays close attention to input from our subscription customers as well as understanding the feature advancements within the real time communications market.
