Application to receive and make calls using multiple phone numbers

We are using RingCentral for our business phone needs. We have different departments with different phone numbers. Certain times, there is a single user that has to handle calls for multiple departments. The user should be able to receive calls made to that department’s number and call using that department’s phone ID.

The final deliverable should be:

A desktop/web based application

Codebase of the application

The application should be able to receive calls and make calls for different accounts.

The user should be able to call using different phone numbers

Ringcentral has very good APIs that would be used in this project.

We prefer C# backend for this project. We are open to other programming languages.

Skills: C# Programming, VoIP, Java, JavaScript
