SBC Dual Cordless Telephone Handsets Model SBC-6028-2HC

I bought this phone because it has music on hold which is a feature I need. The problem is that the phone is so soft you can barely hear what others are saying. And they can't hear me either. In fact, you have to talk on speaker or you really...

These phones are not what I expected. They have no jack for a headset and the address book must be entered in each phone (quite tedious and time consuming).
