Draft: Implemented ubus events for Telco Voice Manager to notify DECT TR tree changes
The commit introduces the following events:
"voiceServiceAddObject"
"voiceServiceDeleteObject"
"voiceServiceUpdateObject"
This is necessary since Device.Services.VoiceService.1.DECT.Base/.Portable is updated dynamically
but TVM caches TR values and has to be notified of each change.
