Distinctive ring not working?

[Russell]

Two calls today (one real followed by one test) - and distinctive ring which worked before (Ring Tone 2) no longer works. The test was calling the main home number from a cell phone. We've been on vacation for a while with no child at home and so the home phone was turned off and saw minimal use, so I'm not sure when this stopped working - I'm fairly certain it worked yesterday morning. Our use should be returning to normal soon and if I don't get any follow-ups on this thread, I'll probably open a ticket.

Edit: Just checked the vPanel and it's interesting what I see under Devices - I wonder if there's a cause there for the behavior described above.
