There is no external IC to control its incoming voice. There is no volume level option for the incoming caller voice leveling. You can a little bit manage to repair it by cleaning the motherboard. Do not forget to dry your cell phone motherboard after cleaning it with an electronics cleaner.

If the mobile phone has a water damage issue. Try to find some missing, burning resistance or capacitors on its motherboard. You can resolve it by re-soldering or replacing any missing, damaged part before replacing it. Some time earpiece and its pinpoints are working fine. But the ringer in fitting with the front panel has a connection issue. In this situation, you can try a direct jumper from speaker pinpoints to its holder pinpoints. I have fixed this issue many times by re-soldering its speaker pad pinpoints.
