[VoiceOps] Poor LD from Ontario, Canada

Our customers (including my family) have been complaining over the last few months about poor call completion and quality to the Midwest. Based on the random CID (or lack of, when I see "Private Caller"), it's clear that Bell Canada is doing some LCR over poor and/or dubious routes. Some calls don't complete, or when the called party picks up, it immediately disconnects, or the quality is very poor. Does anyone have a contact at Bell Canada that would be able to help sort through this? Please reply off-list. Frank
