I just setup Nettalk Duo and can send and receive calls. But the Answering machine will not work. I have it set for 4 rings and Nettalk voicemail is set for 5 rings. Any suggestions, please help.

For more details on how to setup your Lexmark X4650 printer for faxing, please refer to the User's Guide found on the Lexmark website.
Additional info:If you have an answering on the same line as your fax:

To make sure the printer picks up incoming faxes, set Auto Answer to On, and then set the printer to pick up after a greater number of rings than the answering machine. For example, if the answering machine picks up calls after four rings, then set the printer to pick up after six rings. This way, the answering machine picks up calls first and your voice calls are received. If the call is a fax, then the printer detects the fax signal on the line and takes over the call.

If you have a voicemail feature associated in the same line as your fax:

Voice mail and fax can share the same telephone line if you subscribe to a distinctive ring service offered by your telephone company. This feature allows you to have multiple telephone numbers on one telephone line. Each telephone number has a designated ring pattern (single ring, double ring, triple ring, or double and triple ring). The different ring patterns let you know which telephone number was dialed, and which device you should use to answer the call.

If you do not have distinctive ring service, then set the printer to receive faxes manually (Auto Answer Off). This setting lets you receive both voice calls and fax calls, but works best if you use voice mail more often. You need to turn off voice mail whenever you are expecting a fax.

Are you sharing your home phone line with your fax? If so, do you have a voicemail or an answering machine connected in the same line?

If you have an answering machine connected to the same line as the fax, set the answering machine to answer incoming calls before the printer does. Increase the number of rings by a factor of 3 over the answering machine. For example, if the answering machine is set to pick up on 4 rings, set the printer to pick up on 7 rings.

If you have a voicemail feature in the same line as the fax, you may subscribe from your phone service provider for a distinctive ring pattern feature. You can program your printer to have a distinctive ring pattern and phone number for incoming faxes.

Set the fax machine to Manual Receive. Set your answering machine to 4 or 5 rings. When the phone rings, pick it up, if you hear the chirping of a sending fax machine, press the Start Key on the fax and then hang up. The two faxes will communicate and you will receive your fax.

Check the number of rings your fax machine is set to. Chances are, the answering machine is set up for 4 rings and the fax machine is set up for 6. If this is the case, change the number of rings on your fax machine to 2 or 3 rings to ensure an incoming fax will go directily to the fax machine. If the fax doesn't recognize the call as a fax, it will go through to the answering machine.

make sure your answering machine is plugged in to the "EXT" jack on fax machine, and your main line plugged into "line". try setting fax rings to 1 or 2. set your answering machine to 4. your fax should intercept the call and if it hears the fax tone, will receive the fax. if it doesn't hear the fax tone, it should forward the call to your answering m/c.

• If the printer detects a fax, it receives the fax and disconnects the answering machine.
• If the printer does not detect a fax, the answering machine receives the call.
2 Set the answering machine to answer incoming calls before the printer does.

3 To set the number of telephone rings before the printer automatically receives faxes.

The Rings to Answer setting is important if you have an answering machine on the
same phone line as the HP All-in-One, because you want the answering machine to
answer the phone before the HP All-in-One does. The number of rings to answer for
the HP All-in-One should be greater than the number of rings to answer for the
answering machine.
For example, set your answering machine to a low number of rings and the HP All-in-
One to answer in the maximum number of rings. (The maximum number of rings
varies by country/region.) In this setup, the answering machine will answer the call
and the HP All-in-One will monitor the line. If the HP All-in-One detects fax tones, the
HP All-in-One will receive the fax. If the call is a voice call, the answering machine will
record the incoming message.
To set the number of rings before answering from the control panel
1. Press Setup.
2. Press 4, and then press 2.
This selects Basic Fax Setup and then selects Rings to Answer.
3. Enter the appropriate number of rings by using the keypad, or press or to
change the number of rings.
4. Press OK to accept the setting.
