Forward a Call via Voice Proxy with Ruby on Rails

Creating a voice proxy using the Nexmo Voice API allows users to make phone calls with confidence by masking their private phone number. To achieve this, users need to set up a Ruby on Rails application, expose it externally using ngrok, and link it to a Nexmo account, phone number, and Voice application. The application is then configured to forward inbound phone calls via voice proxy to the user's personal number, with options to announce or silently forward the call. With this setup, users can make secure and private phone calls while maintaining their anonymity.
