Did you mean you got ICMP messages back from some router on their network in
response to the UDP transmissions you were sending? Not TCP, surely...

I too have a customer in the same area with the same exact problem. However
they are doing SIP over UDP, and initially inbound SIP packets from my server
headed to the client at frontier were getting rejections. I could see their
SIP packets, but they never got mine, but I did get TCP rejection
