IP Phones are not working

All 3 of our phones, Model # Cisco IP Phone SPA 525G are not working. We can get a dial tone but we cannot hear callers and they cannot hear us.  We share an office with another doctor and they use the same modem, router, etc. but with a different phone #.  Their phone is working.

 

On the display screen their phone shows a phone icon on the far right, ours shows an envelope with a phone receiver at an angle.
