auto-attendant VOIP soho service

Archived from groups: comp.dcom.voice-over-ip (More info?)

I'm looking for an inexpensive VOIP service provider that provides
auto-attendant features with multiple voice mailboxes.

You know: "dial 1 for sales, 2 for billing, etc" for that big-company
feel--even though it may just be one actual line.

Packet8 seems to have lots of good features in their business plan, but I
don't want to be obligated to get 3 lines and adapters right away.

I'd also rather not have to set up a Linux server, etc to do it inhouse.

Any ideas? Thanks.
