What type of phone is this? Most home phones have a setting in them to adjust the number of rings. Retrieving voice mails requires the voice mail be set up first. To assist you further, please provide more details.

According to iPhone faq.org: " How can set the number of rings on my iPhone before voicemail picks up?
You can set the iPhone to wait longer or shorter than the default 20 seconds before it goes to voicemail when receiving an incoming call. This will result in a different number of rings before the voice messaging system picks up the line and plays your outgoing message. To change the amount of time the iPhone will ring follow these steps:
1. Open the phone app and dial *#61# on the Keypad. Press the Call button.
2. Locate this text on the screen: "Setting Interrogation Succeeded, Voice Call Forwarding, When Unanswered, Forwards to +" and record the 11-digit number after the + symbol.
3. Touch the Dismiss button. Now enter this code on the Keypad: *61*+ followed by the 11-digit Forwards to number recorded in step 2, followed by *11 and *ringtime#. Ringtime is the number of seconds you want your iPhone to ring before voicemail picks up. Your finished code should look something like this:
*61*+18555513466*11*30#
In the example above the ring time is set to 30 seconds. Press the Call button.
4. You should receive the message: Setting Activation Succeeded. Press Dismiss and next time you receive a call it will ring for the new amount of time before going to voicemail."
According to Apple Tool Box.com: "having this problem, please try the followings:

• Make sure that iPhone's Ring/Silent switch is OFF meaning ringer is ON. A bell will flash briefly on the screen when you turn on the ringer.
• Make sure that the Do Not Disturb setting is not silencing calls (Settings > Do Not Disturb).
• Make sure that Airplane Mode is OFF (Settings > Airplane Mode).
• Make sure that your carrier software is up to date (Settings > General > About)."

Setting the Number of Rings (Excerpt from the Uniden Dect 1580 Phone manual

The ring time setting allows you to set the number of rings the caller hears before your answering system plays the outgoing message. You can set the ring time to answer after two, four, or six rings. If you enable the Toll Saver (TS) setting, the answering system picks up after two rings if you have new messages, and after four rings if there are
none. This way, if you make a long distance call to check your messages, you can hang up after the third ring to avoid long distance billing charges.

1. Press Menu/Select.
2. Select the Ans. Setup menu, and then the Ring Time submenu.
3. Move the cursor to select a ring time (Toll Saver, 2 Times, 4 Times, or 6 Times).
4. Press Menu/Select. You will hear a confirmation tone.

To place the handset in Silent / Vibrate Mode
Step 1
To place the handset in Silent / Vibrate Only Mode, hold down the pound key (#) for about 2 seconds. To exit Silent / Vibrate Mode, perform the same action while in Silent / Vibrate Only Mode. You will see a confirmation message for Silent / Vibrate Only Mode, each time you enter or exit Silent / Vibrate Mode.
The SCH-U470 (Juke) handset will vibrate rather than ring when you receive a phone call, message or alert while in Silent Vibrate Only Mode.
Step 2
While in standby mode, press the volume key, located on the left side of the handset, then select either “Vibrate Only", “Alarm Only” or “All Sounds Off”. To disable perform the same action while in Silent / Vibrate Mode.

After making my post, I went to the official Brothers website for the 4100 FAQs and "Operating Instructions." Here's what I found. Set your 4100 set to the "Fax/Tel" mode. Press "Menu", then the number 2 (Fax), then number 1(Set-up Receive), then number 1 again (Ring Delay). Use right arrow key to increase. Once increased, press the "Set" key. You'll see the message "Accepted." Now press the "Stop" key to exit "Menu." This will now give you up to 4 rings before the fax auto answers. Inorder to send a signal by phone to remote start the fax just follow the instructions I copied directly from Brothers instructions for the 4100: If you answer the call on an extension phone (this is any phone plug into a phone jack on the same line) and hear a beep every 3 seconds (automatic fax) or just silence (manual fax), press *51(remote activation code) on the telephone keypad, wait to hear the Brother machine turn on (chirping sounds) and then hang up. I don't have anyone that can send me a fax right now to test it out. I'll have to try it in the morning. Hope this works for you.
