I just bought the Linksys CIT310 IP Wireless phone

Apparently the store that I bought it from had old stock as this was over 1 year ago out warranty the Linkskys' company said. I have it hooked up.

The problem is that when I place outbound calls to land phone calls or in coming land line calls. I can't hardly hear the person talk. My husband has used the phone as well. He has difficulty hearing the other person speak too.

I've looked through the manual and can't find any way to turn up the quality sound of the hearing only the telephone ring sound. I turned up the telephone ring sound but still there is no improvement in the hearing quality of this telephone.

If I can't improve the quality of the haring people speak on this telephone I will return the phone and get my money back as this is useless to me.
