Nokia Home Internet Gateway - Issues list

I am unable to use the Gateway to connect with my Cisco IP phone. Is there any way at all to get T-Mobile to understand that blocking ports and not allowing the user to configure ports on the home page interface prevents their Gateway from working with various equipment like IP phones? I have called customer service multiple times. They promised a call back which never occurred. I was on hold with one agent for 20 minutes who didn't know what I was talking about and did a Google search to look up the problem. I have seen multiple complaints on this forum, but wonder if T-Mobile reps even read them. Very sad.
