I realized today that my call waiting isn't working properly. If I am using the FXS attached phone and a call comes in the FXO, it just goes directly to voicemail, with no indication (call waiting beep). If I flash there is a second dial tone, and I can initiate a second call. If I am dialed out through the FXO and another call comes in I hear the call waiting beep, when I flash over I hear another dialtone rather then the incoming call. With the HT-488 this feature seemed to work. With my new Wellgate 3701a I don't know what to do to make it go? Thoughts, ideas, suggestions welcomed. Marty
