From Mark Boolootian:
So, my meta-question is: Shouldn't there be an informal arrangement that
allows one provider to open a trouble ticket with another provider if the
providers peer with one another?
We have always honored trouble tickets from any ISP, and we have opened
TT's with MCI.
We're a customer of Sprint, so I can't speak of any problems we've had
in regards to trouble tickets with Sprint.
