    Ah, my apologies then. Sounds like two different problems?

    I cannot believe it
    My hearing impair works to my advantage
    J/K, I do not think I've ever heard the DTMF tone with my SPA-1001
    being a very old ATA, perhaps, it's impervious to the problem!?!

    my wish list:
    1. Intelligent Call Forwarding that detects the incoming call originated from the "forwarded" phone and rings the original destination instead
    2. Call History that makes use of CallerID/Custom CallerID+Location. Call History only shows Custom CallerId+Loc. No CNAM look up; Albeitly,it's a step in the right direction!
    3. Scheduled sim. ring with a twist (see wish #1)

    After making the suggested changes, I still hear the tone(s) calling the VOIPo line from a wireline. It seems to be related to the pitch of the voice as I only hear the tones while talking to my wife or daughter. When I am using the VOIPo line, the person on the other end, using a landline, never hears them. Could this also be related to inbound vs outbound calls?

    I would think you should only hear these erroneous tones outbound.
    Inbound would be the sending equipment's job.

    My suspicion, though, is that the ATA can incorrectly generate a DTMF tone and play that out the FXS port if it thinks it heard one or something?
