Parasonic auto-logic answering machine

We are trying to connect this to a multi roll over state agency phone, when I plug the machine into the phone, the phone goes dead, does this mean the answering machine will not work on this phone system?

Hello, yes it sounds like your trying to connect a "analog device" to a "digital" telephone. If you wish to connect the answering machine to answer your line or lines, you should contact your facilities maintenance department and see if they can "hardwire" your telephone line (your primary phone number), to another jack in your office so your answering machine will work by being placed in "parallel" with your phone system and your primary phone number. If you have more than one phone line (number) you wish for the machine to answer, you will need to ask for a "analog extension" from your digital phone system and have it programmed to ring when any of your roll over lines ring. However, keep in mind the machine can only answer one call at a time, the other simultaneous callers will get a ring no answer until the first caller has hung up. Good luck, hoped to help. CG

I have the fax connected to the phone line with a splitter which is also connected to my portable phone and answering machine. when the phone rings it goes to answering machine if not answered and then to...

The fax machine should have two places on the back where you can plug in a phone cord. One of these is the input: where the cord from the wall goes, and should have either "in" or a picture of a wall phone outlet next to it. The other is used as a line through the fax machine and should have a picture of a phone or "out" next to it. Ideally, you would plug the fax machine directly into the wall and then your phone/answering machine into the "out" plug on your fax machine.

When in auto mode, the fax machine will listen in on the line when the phone rings and if it detects a fax signal (all the whirring and beeping) it will pick up the phone and receive. If there is no signal, it will simply allow the signal to pass through to the phone and answering machine.

I am trying to hook up my digital answering system with a multi line phone. I need step by step what I need to do. Thanks Ivy Hutchison

The answering machine would plug into the telephone jack on the wall, and the telephone would plug into the jack on the rear of the answering machine.
Now you do mention that the telephones are multi-line units. This could complicate things a bit because the 1739 is a single line answering machine.

If the telephone does not have individual jacks for each line (a jack for line 1 and another jack for line 2) you would need to purchase an adapter (maybe 2 of them...depending on the wall jack) that takes a 2 telephone lines and splits them into 2 individual jacks.

For example:

After the lines have been broken out, you can connect the answering machine to the line that needs it. You would then either plug the lines into their respective jacks on the wall, or use a 2nd splitter to combine the 2 lines back at the wall jack.

I just purchased this phone and hooked everything up correctly, but the Line in use light is on and the handheld states line in use and the answering machine will not respond to pick up messages. What is...

The phone will do this if it isn't (or thinks it isn't) connected to a working phone jack. Try a known good phone (corded type) in the jack to verify that in fact there is dial tone there. Also make sure that the line cord is firmly plugged in at both ends until the latching tabs snap into place. Sometimes it's just a poor connection because the plug isn't all the way in. You can also try another line cord. Bad ones do pop up sometimes.

If everything is correct with the phone jack, take the phone back to the store for an exchange. You have a dud.

Only one phone will dial a number...

Most multi-handset systems require 'registration' of the rest of the handsets otherwise the system doesn't know how many stations are in use for intercom and conference purposes.  Check your instructions for how to do this on your system.
Checking 'voice mail' can differ from one system to another; this can be a function of your local telephone service and would require 'caller ID' service being active, in other systems, this just gives you remote access to your answering machine (ours does that).
If the software is logical, choosing the 'Menu' should give you the chance to listen to messages from any handset once they are registered on the system.

Don't know how to connect

Hi, I'd love to help you with the problem you described.

  1. Connect your phone line (out of the wall or your phone modem supplied by your phone or cable company) into the jack on your MFC-240 has a picture that is shaped like a little telephone. These jacks are located on the lower left back corner when you are facing your printer.
  2. In the same location, there is another jack right next to the one you just plugged into. Take the phone cord that came with your printer and plug one end into the jack.
  3. Plug the other end of this cord into the base of your phone or answering machine.
  4. Test your connections by picking up your phone handset and listening for a dial tone.
  5. Next, set the receive mode your printer for fax only (if you set the receive mode to phone/fax or other mode, you could experience problems with your voice mail). Fax only will ensure that your printer will only answer fax calls. Here's how you do it.
Here's how:
  • Press the menu key on your MFC-240
  • Press 0 (display switches to initial set up)
  • Press 1 (display switches to receive mode)
  • Fax only should be the first item that shows on the display.
  • Press the ok button on your MFC-240. The machine is now ready to receive faxes.
If you have not done so already set up either your answering machine or your cable company voice mail.

AT T 984

I was told by an AT&T rep that the auto attendant can forward calls to another 984 phone to leave messages for that person. Your original OGM (out going message) on the designated Auto Attendant phone should state greeting and the names and the extensions. The caller presses the buttons for the person they want to reach and their call is forwarded to that extension. That extension, if unattended, will have an OGM telling the calling who they have reached and to leave a message. This feature can only transfer calls to other 984 phones only.

Need to connect ans. machine to single line on a multi line business phone. Help!

Out of box, the AT&T 1738 is designed to operate on a single telephone line. I don't know of any device on the market today that could automatically switch it between multiple telephone lines.

Some options include (in no particular order):

1) Purchasing additional 1738s to cover the other telephone lines.

2) Some cordless telephones on the market are designed to handle 2 telephone lines. Their answering machines will cover both lines. AT&T and Panasonic offer such phones.

3) Check out AT&T's line of NoKSU small office telephone sets. The phones will handle up to 4 telephone lines and 1 model features a built in answering machine. In order for the telephones to function 100% all phones would have to be replaced with the models within the AT&T NoKSU family.

4) If this is strictly a business application, consider purchasing a true business telephone system for the office.

Will not send faxes

Make sure the phone line is plugged into the LINE jack on the fax, NOT THE PHONE JACK. The phone jack is to add a telephone to the fax. If it is connected properly, try calling your fax from a cell phone and see if it answers. If the fax answers, hang up and press the HOOK button on your fax and use the fax keypad to call your cell. If the cell rings, answer the call and listen for the fax machine tones. If you hear the fax on the cell, you may have to change your machines TRANSMIT or DIALING settings.

Connecting additional telephones

The only other way around is to fit a double adapter into the phone line socket and plug fax in one and the phone in other, this way both will ring and allow you to make or receive calls on the seperate handset
