enableCNG method
Enables or disables Comfort Noise Generation (CNG).
CNG generates artificial background noise during silent periods to avoid dead silence, which can make users think the connection was lost.
Parameters:
enable: Whether to enable CNG (default: true)
Returns 0 on success, negative error code on failure.
Implementation
Future<int> enableCNG({required bool enable}) async {
throw UnimplementedError('enableCNG has not been implemented.');
}
