Adjust the Volume During a Call

If the sound in your handset, headset, or speakerphone is too loud or too soft, you can change the volume
while you are listening to the other person. When you change the volume during a call, the change only affects
the speaker you're using at the time. For example, if you adjust the volume while you're using a headset, the
handset volume doesn't change.
Procedure
Press Volume up and down to adjust volume while you are on a call.

Adjust the Phone Ringer Volume

If your phone ringer is too loud or too soft when you get an incoming call, you can change the ringer volume.
Changes to the ringer volume do not affect the call volume you hear when you are on a call.
