Not SBC DSL compatible

This machine worked okay until I had SBC DSL installed. Even with a filter on the line, it absolutely won't record incoming messages. The phone rings the specified number of times, the answering machine begins to pick up the call then beeps and seems to turn itself off, as if it thinks that the phone has been picked up. The same thing happens even if I plug the answering machine into a phone jack different from the one connected to the modem.

Prior to the DSL installation, it worked okay. It was really simple to operate. The incoming and outgoing messages played pretty clearly, but I wasn't super impressed. I'm angry that I was only able to use it for 3 months before needing to find one that is DSL compatible.
