Decibell
One app. Every number. All your calls and messages.
Overview
Decibell is a cloud-native unified communications platform that lets you purchase phone numbers from multiple telecom providers, send and receive SMS, and make VoIP voice calls — all from a single app. Whether you need a local number in another country, want to keep personal and business lines separate, or orchestrate communications across Twilio, Telnyx, and Plio from one place, Decibell handles it. Built on a scalable cloud backend with real-time messaging, native CallKit integration, and an admin dashboard that gives operators full oversight of users, providers, and routing rules across regions.
Features

Voice Calls
Make and receive crystal-clear voice calls over the internet using any of your numbers. Incoming calls feel just like regular phone calls — even when your screen is locked.
