My name is charles katura from diaspora telecom. We would like you to work on our customized csipsimple dialer and complete it as the developer who was working on it earlier got other responsibilities and couldn't complete.
We will provide you with the android source code of what he had done as he was almost finished. The only major thing left is to implement our api to work with the app.
1) it will be able to send sms using our api
2) it will be able to send credit using our api
3) it will be able to use localaccess number to dial out if no internet connection.
4) it will be able to perform ussd commands using our api
5) it should be able to display balance
6) users will be able to topup using paypal from the app
7) new users will register using their phonenumber and on successful registration, the sip registration details will be auto provisioned on the sip client. The registration process of a new client has also been complete.
The UI was already made that takes care of the above functionality only thing left is to attache our api to work with the app so as to do the above.
I will provide you with the api if you accept this project.
