Developer a SIP voip client Android and iOS

I want to build a customized SIP/VoIP Softphone with one new Skin design as per choice and my logo for unlimited user license that runs on Android and iOS app.

I would like that the cost of project be showed in separeted Android and iOS and hope that the developer use other solutions to do that, doesn't start by the zero.

I hope at least these features in the 1st step of the project:

- make and receive calls and video calls;

- access the contact list of mobile to make calls;

- register the calls realized in the history;

- make conference (add member in a existing call);

- send SMS and internal messages for your company user;

2nd step project;

- consult the host server and reproduce the calls stored there;

- shows the balance of the user account;

- allow the user to make a recharger by the app;

- open a ticket to complain for my company;

In the end of each step I want the source code of the whole project;

Skills: Android, iPhone, Java, Mobile App Development, VoIP
