Set up 2wire is very easy, been done that hundred, maybe thousands of times and I know this modem very well. It is great modem and yes it will work with Sorenson VP100 or VP200.
I do not believe that from a reliable and knowledgeable technical support representative would advise avoiding 2wire modem.
