The FCC is investigating -- it's not even clear if it's illegal to do that.
For what it's worth, my ISP is owned by my rural ILEC, and I just cancelled my Vonage service because it had become unusable. However, the problem was not TFTP, it was rotten inbound voice quality, combined with a complete inability to contact anyone at Vonage by e-mail or phone to do anything about it. My link is a T1, and it has plenty of spare inbound capacity. Traceroutes suggest that Vonage is suffering from packet loss problems at gateways between their NSP and mine, or perhaps the packet loss within my NSP (Sprint) was too much for it. I switched to Lingo which works fine. Its box uses NTP to set the time, then http to configure. Regards, John Levine, johnl@taugh.com, Taughannock Networks, Trumansburg NY http://www.taugh.com
