I need help setting up the Microsoft Fax. My connection configuration at present is as follows: COMPUTER --- NETGEAR WIRELESS ROUTER ---- DSL MODEM --- DIGITAL PHONE LINE HAS FAX FILTER INSTALLED.

Any Suggestions? When I attempt to fax I receive the error message - NO DIALTONE DETECTED. Cable/DSL provider is of no help.

Thanks,

If you really have a "digital phone line" (such as in an office PBX), then you can't fax using an analog modem -- which is how Windows Fax works -- unless you get a digital-analog phone adapter (this is NOT the same as the filters used to separate DSL signals from telephone service - which is what I assume you mean by "fax filter").

"How do you tell if the phone line is analog or digital? Look at the back of the telephone connected to it. If you see "complies with part 68, FCC Rules" and a Ringer Equivalence Number (REN), then the phone and the line are analog. Also, look at the phone's dialpad. Are there multiple function keys? Do you need to dial "9" for an outside line? These are indicators that the phone and the line are digital."

Thanks for the answer Lem. Now I am confused. I pay Time Warner Cable for Digital Cable, Digital Phone and DSL Internet Service. When they installed the "Digital Phone", I did not have to go out and buy a new phone. I use the same one I used when I was with AT&T. All of these products come into my house through one line connected to a modem and branch off of there. There is a phone cable that connects to a telephone outlet to provide service to the house from the modem. I assume that since Time/Warner provided me with a "Fax Filter" their service isn't truly Digital. Does this help me? Can you provide anymore information?

Thanks,

Blondie

I believe you have cable internet service, not DSL. http://www.timewarnercable.com/

Many cable companies have launched Voice over Internet Protocol (VoIP) phone service, or digital phone service. Digital phone service takes analog audio signals, the kind you hear when you talk on the phone, and turns them into digital data that can be transmitted over cable’s fiber optic network. Part of the "box" provided by your ISP (Time Warner) provides a connection for your regular old analog phone.

In the early days of VoIP, faxing generally was not well supported: http://www.soft-switch.org/foip.html

This may have changed somewhat: http://michigantelephone.mi.org/distribute.html

However, if you look at the forums at BroadBand Reports, the consensus still seems to be that Fax over IP is "iffy." Here's a random thread on the topic from last June: http://www.dslreports.com/forum/remark,16552023

OTOH, according to Time Warner http://www.timewarnercable.com/CustomerService/FAQ/TWCFaqs.ashx?faqID=1205&MarketID=0&CatID=639

Q: Will my fax machine work with Digital Phone service?

A: Yes, fax machines work with Digital Phone service. If you have any problems sending or receiveng faxes using Digital Phone, please contact your local Time Warner Cable customer service office.

You said that TW was of no help. What did they say? I assume that when you pick up your regular phone you hear a dial tone. Try connecting your telephone to the "fax filter." Do you hear a dial tone? If not, the fax filter may be defective. Try connecting the fax filter to the phone jack that your phone is usually connected to; now do you hear a dial tone through the fax filter?

If you can't hear a dial tone when you connect a telephone to the fax filter, the fax modem in your computer won't hear it either, and won't work.
