We are looking that can do a mobile application similar to Viber for android and iphone and all the phones that [login to view URL] supports including desktop. It will integrate with phone contact list to do free voip calls between users, and paid voip calls to other contacts/destinations, send messages to user, show call history, dialpad to call numbers, integration with phone dialing in order to ask user if we want to use our app to place calls, or doing calls normal by phone. Also we will need a tab with more services to show the user more [login to view URL] Up Account Balance. Activation should be done through email instead of calling or texting the person signing up. We also require the app which must be similar to viber in functionality + it should also support video, The microphone icon should also be replaced with a walkie talkie icon. We require the mobile app with complete source code as well as the server side installation/configuration and re-branding. We will get you server/softswitch/voip switch whatever you require, if you have develop anything similar to this type of app you would be given preference. We will also need a demo of the project. Only persons offering a demo need apply please. Only those developers apply who have developed mobile dialer in the past with reference to their old work.
