I'm in the market for an all-in-one and have read good things about the Canon MP780. However, the reviews at Amazon point out that it doesn't have fax/voice autoswitching. I've not used an all-in-one (or even a fax machine except on a dedicated fax line), but at home I'd plan to put the all-in-one on my second analog line (the other number also carries my DSL). Will anyone who calls on the second line get the fax screech a few seconds into our conversation no matter how quickly I pick up the phone? And, if I answer the phone and get the screech from the other end, will I have lost the opportunity to have the MP780 see the call? Thanks so much, Jim Robertson --
