Verizon Stripping and dumping packets

Verizon is discarding traffic coming INTO their network with a high 
priority QoS tag. Ryan proved this by stripping the QoS tag out of an 
Edgewater on our IP to a VZ IP. Traffic never made it to the far router.

The other piece is they are changing the packets:
Packet leaves like this
17:13:01.741406 static-96-254-116-37.tampfl.fios.verizon.net.500 > udp 80 (DF) [tos 0xb8]
and arrives like this
17:13:01.812518 static-96-254-116-37.tampfl.fios.verizon.net.500 > udp 80 (DF) [/_tos 0x18_/]

They have broken VPNs and SIP traffic for a large amount of FiOS customers.
