Hi
Could be a loose connection on your phones speaker.Have it checked or probably replaced.
Does it vibrate?
Make sure the phones no set to mute on your profiles settings.

These are the instructions from the manual, which I found here:

RING SELECT (FOR ANSWERING MACHINE)

This feature lets you select the number of times you want to phone to ring
before the answering system answers a call.

1. Make sure your phone is OFF (not in talk mode).
2. Press the MUTE/PROG button to go to the main menu.
3. Press CID/VOL (up or down) button to scroll to HANDSET SETUP.
4. Press MUTE/PROG button to confirm.
5. Press the CID/VOL (up or down) button to scroll to the RING SELECT menu.
6. Press MUTE/PROG button to enter the menu. RING SELECT 3 4 5 6 TS shows in the display.
7. Use the CID/VOL (up or down) button to scroll to the your selection. The default setting is 5.
8. Press the MUTE/PROG button to confirm. You will hear a confirmation tone and the new setting shows in the display.

NOTE: If you select Toll Saver (TS) the unit answers after the 3rd ring if there
are NEW messages, OR the unit answers after the 5th ring if there are NO new
messages. This allows user to access their answerer from another location and
then hang up after 4 rings to save long distance charges.

Receiving Calls
1. To answer a call, touch or open the slide.
 If the slide is closed, simply slide it up.
 If the slide is closed, press the Voice
Commands key twice, then touch .
 If the slide is open and the touch buttons are
lit, touch .
NOTE If you touch Left Soft Key [Quiet] while the
phone is ringing, the ringing or vibration is muted
for that call.
NOTE If you touch Right Soft Key [Ignore] while the
phone is ringing, the call will end.



Mute Function
The Mute Function prevents the transmission of
your voice to the caller. To quickly activate Mute
touch Left Soft Key [Mute], then to unmute
touch Left Soft Key [Unmute].

NOTE! while doing this you must call someone then while talking with him touch Left Soft Key [Unmute] to Unmute

Hope it help you out ^_^
