I am looking for an experienced VoIP/PBX developer to create a complete VoIP calling system from scratch and integrate it into my existing Django-based CRM. The goal is to enable users to make and receive calls directly from the CRM interface using a secure and reliable VoIP solution.
Requirements:
Setup of VoIP or PBX system (Asterisk, FreePBX, or any suitable open-source solution)
SIP trunk configuration for call routing
WebRTC or softphone integration for browser-based calling
Call functionalities: outbound & inbound calling, call logs, call recordings, status tracking
Route incoming calls to CRM as well as to a physical phone number (e.g., mobile or landline)
User authentication and role-based access control for call features
API endpoints to interact with Django backend (or direct integration)
Basic dashboard/reporting for call activities
Documentation for system setup and deployment
Preferred Tech Stack:
Asterisk / FreePBX / FusionPBX / FreeSWITCH (open to recommendations)
WebRTC / SIP.js or similar for browser calling
Additional Notes:
Should be scalable and secure
Clean and maintainable code
Deployment on my VPS or cloud server
Open to suggestions and best practices from the developer |
