Приложение для телефонов с ОС Андроид (4.0 или выше) которое сможет получать звонки через SIP и перенаправлять их в GSM сеть. Такое приложение должно перенаправлять аудио и конвертировать SIP в GSM и наоборот. В связи с этим, есть несколько основных вопросов от решения которых зависит возможность реализации данного проекта:
1. Нужно ли этому приложению рут на устройстве Android? Так как настройки безопасности Android, по умолчанию, не позволяют перепродавать звук через GSM модуль из сторонних приложений.
2. Похоже, что у нас будут проблемы с управлением вызовами, потому что нам нужен доступ к исходному коду Radio Daemon и Radio Interface Layer (RIL) Для управления нашим вызовом. Верно? Возможно ли решить данную..
ENGLISH
Application that runs on Android phones (4.0 or above) and can receive calls through SIP and forward it to the GSM network. It should be able to connect to SIP server and receive calls like many applications do this. For example: “Zoiper” or “Linphone”. But then, after call is received from SIP server – application has to make call via GSM network to the destination number (in SIP it will be configured). So, Application has to receive call and at the same time make call via GSM. After GSM call was started – immediately connect to it SIP side. It will be like GSM Gateway. There is SIP side and GSM side with sim card. Call is forwarded from SIP server to GSM network. The application should then forward the audio and convert from SIP to GSM and vice versa. Concerning this application there are several main issues and, on its solution, depends the success of this project: 1. Will this application need root on Android device? Because Android security settings, by default, do not allow to transfer audio via GSM module from third applications. 2. It seems that we will have a problem with call control because we need access to Radio Daemon and vendor Radio Interface Layer (RIL) source code to manipulate our call. Isn't it? Do you have any solutions for this? Is it possible to solve this problem at all? Because this application has to work on any Android device regardless of the device model and its processor.
