Ready-Made ASP.NET React CRM

Project Title
Looking to Purchase a Complete SaaS CRM Source Code (ASP.NET Core + React + TypeScript)
Project Description
I am looking to purchase the complete source code of an existing, production-ready SaaS CRM built with ASP.NET Core (Backend) and React + TypeScript (Frontend).
Please note: I am NOT looking for someone to build a CRM from scratch. I only want to buy an existing CRM project with complete source code and commercial usage rights so I can customize and use it for my own business.
My goal is to launch a cloud-based CRM platform similar to Zoho or HubSpot for multiple companies.
Required Features
Multi-Tenant SaaS Architecture
Company Registration
Company Admin Panel
Super Admin Panel
User & Role Management
Lead Management
Customer Management
Contact Management
Sales Pipeline
Tasks & Follow-ups
Dashboard
Reports & Analytics
Activity Logs
Email Notifications
Secure Authentication (JWT)
REST API
Responsive Design
SQL Server or PostgreSQL Database
Call Center Features
The CRM will be used for US outbound sales and call center operations, so telephony and security are extremely important.
Required features:
Click-to-Call
VoIP / SIP Dialer Integration
Twilio / Telnyx / Plivo or similar integration
Call History
Call Recording (Preferred)
Auto Call Logging
Number Masking
Important Security Requirement
Customer phone numbers must NEVER be visible to agents.
Agents should simply click the Call button inside the CRM. The CRM should connect the call through the dialer while keeping the customer's real phone number completely hidden.
The goal is to prevent data theft and protect customer information.
