I'm running into an issue with multiple windows 2008 servers and faxing. Each server is using a new zoom usb modem. It works fine for a while then one of 2 things happen. The modem disappears and needs to be removed and re-seated or the fax line becomes unavailable and basically the same thing needs to happen again to fix it. We have tried replacing modems, turning off all power saving on the USB ports. The faxes are set to retry 5 times. Any thoughts, insight, recommendations would be great because at this point not sure what else can be done. Thank you.
