Local VoIP Android App with IVR | Kotlin + Jetpack Compose + Raspberry Pi Asterisk

Описание: 🚀 Learn how to build a local VoIP client on Android that connects to a Raspberry Pi Asterisk server using SIP — now with IVR (Interactive Voice Response) functionality!

In this video, I walk you through the complete setup of Asterisk on a Raspberry Pi, demonstrate a Kotlin + Jetpack Compose Android app I built, and show how to implement IVR menus for handling incoming calls. You’ll see both outgoing and incoming calls, along with in-call features like mic mute, speaker toggle, hold/resume, and custom IVR call flows.
