Open Source vs Commercial Licensing for Telestax Software is a frequently discussed topic in our community forums. Telestax software (Restcomm) fits into a unique place in the telecom applications stack. Restcomm is middleware software that enables telecoms, enterprises, IoT companies and their customers to develop powerful mobile applications. The website at www.telestax.com describes those products and their features to enhance telecom services to end-users.
Restcomm is open source software. It is available to the public under the AGPLv3 license. This license allows free use by everyone – on their own computers or over a network – to create and run Restcomm-based mobile applications. Our source code is available to inspect, understand, and if necessary modify. Our commitment to open source development of our software is a fundamental and consistent strategy of our company. Our customers and business partners can join our open source community at www.telestax.com/opensource.
Telestax software is also available from us under a commercial software license. A commercial license provides many advantages for serious telecom customers and users of our software. These include:
- Professional technical support, including focused maintenance to resolve customer problems. This support includes new and enhanced software releases when first available, as well as influence within the Telestax development team for those new releases. Commercial customers of Telestax receive personal attention.
- Warranties for software performance, reliability, security, and intellectual property in Telestax software. (The open source version, on the other hand, is AS-IS and WITHOUT WARRANTY.) Warranties can help our telecom customers protect their own investment in their applications for their end-users.
- Indemnification for our customers in the event of third party intellectual property claims. Telestax is proud of our careful attention to open source and other intellectual property concerns of commercial customers and we will stand behind our products.
- Relief from some of the licensing requirements of the AGPLv3. The “copyleft” obligations of the AGPLv3 require those who distribute Telestax software – in actual copies or as an application available to third parties over the web – to publish their own source code changes or improvements. The Telestax commercial license eliminates that copyleft requirement for our software. Our commercial customers will receive Telestax software without an obligation to disclose their own modifications and derivative works to their own online customers.
