I just upgraded AT&T from DSL to U-verse. My intent is to drop land line phone and install VoIP phone. I plan to purchase BasicTalk and connect to Ethernet port on U-verse router. Does AT&T have to activate VoIP service in order for this to work? I was under the opinion I could purchase the VoIP device I wanted and plug & dial. Someone told me I have to have AT&T activate VoIP service which is an additional monthly charge.
