- AudioRouteManager: route to onboard speaker when no BT headset is
connected, BT SCO when one is; set MODE_IN_COMMUNICATION + focus.
- aaudio: build with AAUDIO_PERFORMANCE_MODE_NONE so Android routing
(speakerphone) is honoured instead of being bypassed by low-latency.
- DialerScreen: restyled to a stock-dialer layout (large number display,
3x4 keypad with sub-letters, green call FAB, backspace, recent chips).
- InCallScreen: added DTMF keypad (sendDigit) for voicemail/IVR.
- WearBaresipService: on incoming call, wake screen + vibrate + bring
activity to foreground so Answer/Decline is visible.
- Fixed dial normalization (bare extension -> full SIP URI with domain)
and the uap parse in uaEvent so defaultUap is set and calls connect.
- config.static: load g711/opus codecs to resolve 488 Not Acceptable Here.
- Telecom scaffold (experiment): PhoneAccount + ConnectionService handed
incoming calls via addNewIncomingCall to test stock Wear dialer pickup.
- Submodule libbaresip-android rebuilt with g711/opus/aaudio changes.
Verified: assembleDebug green, installs and registers on Galaxy Watch,
incoming call event fires and is handled without crashing.
