No SIP lines in AK. YEs there are 4 waves wavenetted together, all within same 3 mile radious.

I am trying to figure out what on earth is using up the resources. It might be the two phones forwarded to each other, one a digital on the local wave, and another an IP off another wave. Nothing else has changed. This is a customer change. Nothing else is coming up, and no other wave is having issues.
