I'm trying to figure out how to make a conference call (adding and merging phone calls of different contacts - cellular not VoIP) using C# in UWP.
I see the sample code "PhoneCall" provded in github: https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/PhoneCall on how to dial a number:
public async void DialOnCurrentLineAsync(string PhoneNumber, string DisplayName)
{
if ((currentPhoneLine != null) && (PhoneNumber.Trim().Length > 0))
{
currentPhoneLine.Dial(PhoneNumber, DisplayName);
}
else
{
var dialog = new MessageDialog("No line found to place the call");
await dialog.ShowAsync();
}
}
But I don't see any part of the code to add and merge calls.
