My phone stopped ringing.

Hi, my Poblano VLE5 Hot Pepper phone has just stopped ringing about two weeks go. The calls go through,but I never hear them and only know someone called if I check my phone all the time.
I checked to see if I had the ringer turned on,and yes,there's a ring sound. However,I dont hear it either when I click it to listen to it.
I got this replacement phone when my other one died about 6 months ago,so it should be working fine. Does anyone know where I might check on my phone other than where the ring sounds are on settings? I may have changed something I dont know about.
Please help,if you can.
Thank you,
Sandy
