My belief is that VoIP should be ISP agnostic and as a whole the industry is set up that way. When I came across this article Q4 U-verse gains power residential wireline sales, which is essentially a VDSL, I thought it time to give a shout out for something AT&T has done well. VoIP over VDSL works great. Telewebtech has had a number of customers with home offices serviced by U-Verse as an ISP. It handles the voice load well and always seems to be provisioned properly with high quality equipment. We have even seen a few full offices with 10-15 phones use it.
That said, I was always looking forward to AT&T offering a business level of U-Verse. Well, the opportunity is here, but there may be strings attached.
