Description of the Project:
Need one `Android` / `Java` and `iPhone` / `Swift` function that receives 5 parameters:
· extension to dial
and performs a `SIP` call to that extension number.
For Android, a base project will be provided along with a very simple user interface.
The main goal of this function is to mimic [CSipSimple]([url removed, login to view]) when performing a simple `SIP` call. No other features are required like: messaging, videoconference, call forwarding, etc.
If you want you can use whatever [source code]([url removed, login to view]) out there related to [CSipSimple]([url removed, login to view]), but rememmber, you have to reduce and clean the code to keep only the necessary and using the provided user interface.
For iPhone, please, create a similar user interface (same text fields and same buttons) as for Android.
Please, use **open source** (free) libraries. The more community support it has, the better.
To test your function you will use `provided credentials` for a `test end-point`.
As `IDE` please, use `Android Studio` for `Android` and `Xcode` for `iPhone`.
If you are using external libraries, please use Gradle, Maven, etc., if possible.
