applications.

This framework offers a unique set of features ranging from audio/video calls, content sharing,

messaging, conferencing, enhanced address book to social presence. All these features are

implemented in accordance with the standards: GSMA RCS, 3GPP IMS or VoLTE.

Introduction

This document has been written by us (Doubango Telecom) to help developers to quickly create

innovative multimedia applications for the Android OS. If you are a developer and is looking for

the best way to develop a NGN (VoIP, Messaging, Video Conferencing, ...) or rich application

for Android then your are at the right place.
