NovaChat uses the phone as a Server, specifically Erel's HttpServer library.

The data is stored in the phone's memory, and can be limited if desired so as not to use a lot of space.

Four biggest advantages of this Chat are:

  • 1. Chat is simple to use and can be used free of charge over the internet using the No-IP Service [Replace Everywhere where the Ip address is by the domain name obtained in No-Ip and add the port at the end (For example: http://mymane.ddns.net:5588/) and go to put the Ip address by default (127.0.0.1) in your domain name configuration];
  • 2. The data to be sent leaves from the phone to another phone without going through a Server somewhere, so a message cannot be intercepted while being sent, even without encryption the data is safe;
  • 3. Each phone is a Server for the other phones and a client for itself;
  • 4. Chat Brain is a class module that you can modify as you wish.
The advantage is that you can change the data storage to any host or database you want, just change a few lines of code.

For the chat to work, this 3 modules must be able to be: NovaChat, ChatServer and AudioCall.

From that thread, I read ooVoo is dead. Am I wrong?
From internet search:
On June 10, 2014, ooVoo released its app for Windows Phone devices. On September 9, 2014, ooVoo released its Video SDK for WebRTC. On November 25, 2017, ooVoo announced via Twitter that it will be shutting down, citing a lack of profit.
