Viettel OTT – Mocha



Mocha is OTT (over the top) product. User can send message by phone that has internet connection. I worked on this project as Android developer.

We are using XMPP protocol for interacting between client and server. I decided to use asmack (XMPP library for Android) and modified this library for our project. Moreover, I researched about VOIP technique in this project.

Currently Mocha has 2M download in Viet Nam.
