Puzzling review apparently by world-class procrastinator :)
a) As it happens, around March 31, 2009, Verizon terminated VoiceWing service for all subscribers. Thus the posting of such a review in December 2010 does not seem helpful, and may only serve to confuse. »Verizon Ending VoiceWing Service
b) The reviewer also said ""Speed is constant and close to the claimed speed." How does speed relate to a VoIP service?
