remove battery from phone and reinstall after 10 mins... this seems to fix alot of things also go to sound setting a make sure the volume is turned up all the way

Here some solutions for your problem + a link to the user manual.

**Selecting the Ring Tone and Volume
Your phone has five different ringer tone/volume combinations you can choose from.
To select the ringer:
1) With the phone in standby, press [vol/ / ] or [vol/ / ].
2) The phone will sound the different ring tones at different volumes. To turn the ringer
off, select RINGER OFF.
3) When the phone sounds the ring tone and volume you wish to use, press [end].


**Temporarily Mute Ringer
If the handset is off the base while an incoming call is ringing, simply press [end] to mute
the incoming ring. The ringer will sound with the next incoming call.
Note: You can only mute the handset ringer if the handset is off the base when the phone starts
ringing.

Please give me positive feedback if this helps you.

Thanks.

check and make sure you ringer is set to something but silent.

firstly read the operations manual for that phone look on how to adjust the settings of your phone it probably sure was indicated there, because the way i see from what you posted it has no internal circuitry prob. it just needed an adjustment.. hope this advice helps... ;-)

maybe check on the ringer type for restricted numbers- you can change ringers by all calls, restricted calls, and caller id numbers. your incoming restricted numbers is probably set at none or silent

If someone is calling, do you see it on the phone? If so, you may have muted the sound. Try looking for a a button with a music note on the phone. Hold that button for a bit(atleast that's how it works on my phone)

you would have to saved the contacts on your phone memory then assign ringer id to them and pics as well.
