Thanks for the tip. I had those enabled, but not for the EM_W trunks,
only for my POTS end. After speaking with Digium I have disabled them
completely, and I'm waiting to see the results from today's set of calls.
Thanks to everyone so far for the suggestions, it's good to know that
even after all these years (and an absence from the mailing lists) I
still find the community just as helpful and kind as before :)
