Does anyone have contact information for MetroPCS?  We are still getting hammered with calls today and our tandem operator says there isn't much they can do (which I figured).

Below are some examples traces, the first is a call to a ported number that is working correctly, the second is a call without the GAP information.

We have had an ongoing issue where calls to an LNP'd number do not come into our switch with the original called number and they are routed into our company PBX and we end up becoming the switchboard for people trying to reach our customers.  It seems as though we have been more and more of these calls lately.  Has anyone dealt with a similar issue? If so, what was your resolution?
