We block TFTP at our border for security reasons and we've found that this prevents Vonage from working. Would this mean that LEC's can't block TFTP?Was that a device trying to phone home and get it's configs? Cisco, Nortel, etc. phone home and get configs via tftp. Vonage doesn't need to phone home for config. The device is programmed (router) and it registers with the call manager. If you analyze the transactions it's about 89% SIP and 11% SDP.Vonage devices initiate an outbound TFTP connection backto Vonage tosnarf their configs on initial connection and also (presumably) on reboot.I tested the reboot. I didn't see it. I agree in general and think that providers shouldn't block tftp, IMHO.-- Daniel Golding Network and Telecommunications Strategies Burton Group
