* Мост между жизненным циклом P2P-звонка (ChatViewModel) и Telecom. |
||||||
|
* |
||||||
|
* - Регистрирует self-managed PhoneAccount (делает вызовы uTun «настоящими» для системы). |
||||||
|
* - placeCall/addIncomingCall создают Connection через UtunConnectionService. |
||||||
|
* - Хранит Connection по callId и прокидывает state/route из VM в Connection. |
||||||
|
* - Обратные события (answer/reject/disconnect из системного ввода) — через Listener в VM. |
||||||
|
* |
||||||
|
* Всё «best effort»: если Telecom недоступен (нет прав/стека), методы возвращают false, |
||||||
|
* и VM продолжает звонок прежним путём без системной маршрутизации. |
