I get outgoing dialtone and can make calls from that machine. The moment the Samsung is plugged into a jack that's wired BEFORE the system, it rings like a charm.
Hi Larry - The Partner's ring generator doesn't make a nice rounded sine wave, like the phone company's does, it's more of a square wave. Point is, I have seen some devices that simply don't "like" that type of ring voltage, and won't ring from it. If you know the extension number of the port that you are using, you can call it directly on the Intercom from another phone. This will bypass any possible programming error (but I don't think you have any, based on the old fax machine working fine in the same jack). I think that you're just out of luck using this particular machine.
