This is something that anyone should use it, not only the Real Estate Professionals.
Google Voice, of course, is a Google Product. However, it is sleek and useful, too.
I have been using it successfully for almost a decade (?) or started using it as soon as it was available.
Good news is, you can get everything you want to see or feel through Google stores.
Will talk about the features at a later date - but this is a MUST product for sure.
