Depends on what version of DIGITS you are going with!
Are you going with one number, multiple devices, or multiple devices, one number?
We just wanted to reach out with you again to see how this is going and to make sure we answer your questions. Since you stated you have a virtual number, I'm taking it you have the one device, multiple numbers. In that case, everything you do with the virtual number should show up as the virtual number. If that's not the case, we need to know.
The duplicate number program does assign a virtual number as well, but in that case you would not give out the virtual number. You still get the activation number, but as the intention is to duplicate an existing number, your original number would be the only number you need and use.
Hope that helps!
