Query: Poor sound quality

The phone is hard for both parties to understand and the volume is low. I have to use the speaker phone setting for most conversations. People on the other end of the line always ask me whats up with my phone. I have had 2 different multi extension phones and neither has had the same sound quality as my old vTech $20 single line cordless.
