Comswitch 5500 3-Port Phone/Fax Modem Line Sharing Device - Share Phone Lines for Home & Office | Fax Machine & Modem Compatible | Ideal for Small Business & Home Office Setup

Thanks for the thoughtful reviews which got me to try this unit.Unfortunately, there are also reviewers here who can not even read the first page of their manual. Please ignore their whining.I faced a difficult challenge. After purchasing an expensive multifunction laser [$800], Technical support at HP informed me that their best multifunction would not work with VOIP telephone service. They warned that the answering machine would "steal" calls from the fax machine. and it did. BTW, my VOIP is provided by Time Warner Cable- which guarantees that a fax will work on their service.So I tried a Brother machine - much cheaper . Soon their technical support warned of answering machine and fax incompatibliity with VOIP service.So I dropped the multifunction angle. I purchased a separate Canon MF6530 Printer Copier, a Canon Fax Laser L80, and a Panasonic Digital answering machine.I bought the Comswitch 5500, and had all of these devices installed within less than an hour.Everything worked, answering machine, fax, copier printer right out of the box!However, I did find that the remote phones in other rooms rang only once. So - per the manual - I needed to set the ComSwitch 5500 to "semiautomatic".But I got a VOIP message when I entered the codes to do so.So I called ComSwitch technical support. Technical suport answered in one ring!He solved my code difficulty immediately.With this device, you can set up your office and your machines to work the way you do. And, get the quality you need in your office.Again, thanks for tipping me off to the value of this device.
