Something like that, I think. Try dialing *28 and then wait a moment. I get a second dial tone with higher pitch. This leads me to believe the call is going through a second ATA (or something to that effect) which interprets the tones correctly from my ATA and then passes on higher quality tones.

Because of the above, and since I seem to be the only one having this problem, I believe it is the Linksys RT31P2.

I've opened a ticket and will let everyone know how it turns out. That way if anyone else experiences something similar, they can point Tech Support here.
