Hi,
I'm looking for a mobile app that can do voice and video or something similar to WhatsApp that I can have edited and made available to download from Google Play. I was wondering if there is any open source app existing that has both administrative and client end compleated that I can download and customize into a WhatsApp clone of sort. I heard about openfire but I need some advice on what is possible with it in regards to what I need.
If there is a programmer who can advise me on this I would be most greatful.
thank you.
