I need a team who can code in pure C programming language. I need to modify the Linphone SIP client software for Desktop, Android and iPhone. You can see the documentation from here: [url removed, login to view]
Right now all 3 platforms have their own GUI. You can also proposed other Softphone/SIP Client if it is open source and the codes are available for modification.
So here is my project requirements:
1. I would want to create my own GUI design but having the same functions for all 3 platforms
2. I want to hardcode my SIP server details and make it unavailable for users.
3. It needs to be simple to use, where all users needs is to enter a Username and Password to start using
Your bid is for modifying the codes to suit the functions above and also design.
