I've had a TD816 and TVS50 for a few years now and they worked fine until around Christmas. I reprogrammed the TVS and ever since it simply will not pick up incoming calls.

- phones ring three times. Something picks up the line, but there is no greeting or anything.

-After 5 rings, call is dropped and SBC vm picks up the call. (as it should.)

-Tested phone directly on CO's to make sure SBC vm wasn't beating the TVS to the punch. Picks up after 5 rings, just like it always has.

- Did a DIP position 5 reset, redid custom menus, re-recorded everything. Still no go.

- DPT is fine. Can program 'til I'm blue with hyperterm.

- Can dial into vm internally and get to mailboxes and menus just fine.

Auto attendant simply won't - er, attend. Have tried custom, A.A. and V.M. settings for day and night mode. No answer.

Stumped...
