Guy, I have a problem hooking up the above so I can talk, type, and send/receive faxes at the same time. I have an Embarq (now CenturyLink) 660 series modem, a Belkin 'G' series router, an HP Officejet J4580 All-in-one faxer/printer/scanner/copier, and an HP/Compaq Presario desktop computer. It seems that if I connect so I can use the phone/internet, I can't fax; if I connect so I can fax and be on the 'net, I can't use the phone. Filters from Embarq don't seem to help. Any ideas? Thanks.
