Redirect calls from Android app to phone

Programmer services are required. There is a callback widget (the widget is installed on the site). The program works through the Android application, that is, for calls requires an Internet connection. You need to make a redirect: the calls, getting into the program, were forwarded to a landline or mobile phone, the number of which I can set myself. You can add several phone numbers for forwarding.

No prepayment - payment upon receipt
