VOIP SYSTEMS AG and [login to view URL] need a basic SIP dialer for Android, keeping in mind these features:

* PREFERED someone that already worked with Dellmont dialers or similar.

* Dialer itself with all the basic functionality of a softphone.

* Call history (calls made by the app itself)

* Address book

* Login/signup activities

* Source code aviability

There is a pre-compiled APK that can be use for further reference and additional resources.

THIS WAS OUR ORIGINAL PROJECT WHICH NEEDS AN UPDATE NOW WITH NEW PROGRAMMING STANDARDS:

We need a basic voip softphone dialer that works with SIP protocol .

dialer has the cummon dialer options like :

- hang

- mute

- speaker

- dial a number

- dial a number from contacts ( phone contact )

- simple call logs saved in the phone database ( Calls , numbers called, call durations , dates )

the code need to be good for future developments . and use the basic principals of clean coding ( Comments , etc ... )

the preferred platform for the application is : Flutter , React-Native

the voip provider only supports the Standard SIP options , not the SIP Over WebSocket .

The Technical skills required :

- ( Flutter / React-Native )

- Mobile Programming

- VoIP Knowledge

- API Calls

- Android Studio

Thank you!
