Project description:
"*** PLEASE READ IMPORTANT NOTE ***

ONLY BID ON THIS PROJECT IF YOU ARE EXPERIENCED IN WEB APP DEVELOPMENT AND FREESWITCH INTEGRATION, PLEASE DO NOT WASTE BOTH OF OUR TIME IF YOU ARE NOT DON'T HAVE PRIOR EXPERIENCE IN DEVELOPMENT AND FREESWITCH.

I’m building a browser-based virtual number buying platform and need the voice layer hooked up to FreeSWITCH. The web app itself still has to be put together, so the project covers both the application stack and the telephony integration.

Core scope
• Build a responsive web interface where users can register, log in, buy numbers, configure calling features, see their contact list, and place or receive calls on mobile app and PC browser.
• Perform SOFIA Mod api integration and enable real time data sync and telephony service with FS on developed web app
• Provide a clean REST/JSON API that the front end for management and call control.

Tech preferences
I’m comfortable if you work in a common JavaScript stack—React or Vue on the front end, Node.js or Python for the back end—as long as you can demonstrate solid experience with FreeSWITCH, and SIP signalling.

Deliverables
1. Source code for front end and back end, well commented.
2. FreeSWITCH dial-plan snippets or XML configs required for the integration.
3. Environment setup script (Docker compose is fine) so I can spin up the entire system locally or on a cloud VM.
4. A short walkthrough document describing how user provisioning, call flow, and any custom modules are arranged.

If all looks good we can discuss follow-on work for voicemail, recordings, and mobile clients." (client-provided description)
