iPhone VOIP based voice calling application

We are an ITSP who are looking to build a VOIP based voice calling application on the iPhone and later on android.

Application will most likely require a dedicated server to act as an intermediary between the iPhone app and our voice billing system.

Our goal is to create an app with close to zero signup input to allow users to make voip tp voip calls for free with an extra function of adding balance to their account to allow them to make outgoing calls to standard number.

Will need to have some sort of sip dialler integrated into the app, as well as account management features.

Our voice billing switch has an API which the app can communicate with to make account changes and fetch account information.

More information will be given about specifics once bid is made.

Require professional developers to carry out this project.

Skills: Android, iPhone, Mobile App Development, VoIP
