Please be careful the open source projet is very different from the product. The product use the same code from the open source platform, but the portal, the app web, mobile etc … are completely different. We are using the same API for the project and the product. We are not offering any support for the open source project except our free time on forum or mattermost channel. I dont know if there is some people who want to help you or offering consulting for money but you could ask in channel or forum.
I give you a translate version from my french post few month ago about that: Différence entre les versions
Wazo is a cloud product published by the company Wazo Communications Inc based on the open source project (free software GPLv3) Wazo Platform.
wazo.io: is the site of the product and the company.
wazo-platform.org: is the site of the open source project.
So we are using the open source project to make it a commercial product addressed to operators / integrators who resell it to end customers.
As explained by @ddfdom our applications are all based on the platform APIs and have been built around an SDK that we provide under the MIT license. https://github.com/wazo-platform/wazo-js-sdk
Web application: https://github.com/wazo-platform/wazo-webrtc-demo
Mobile application: https://github.com/wazo-platform/wazo-react-native-demo
The product around unified communication that we have developed (https://wazo.io/enterprise-unified-communication/) consists of a cloud management portal to manage all of its customers as well as applications for end users in web (cloud), desktop and mobile version, as well as a chrome plugin.
Any developer can take over wazo-platform and build their own solution / product around the platform. In fact, we are very open to seeing products built around the platform and to seeing contributors to help us move it forward. We have made an eco-system page to precisely highlight them. https://wazo-platform.org/ecosystem.
Hope this is clearer
For information AWS just published the latest version for wazo-platform 20.12.
