Phone line, forwarding, need help?

I need to set up a phone line, that when called will redirect the call to a cell (one on a list of many). If a cell is not avalible, it needs to move to next. What are my options and what is average pricing?

then why don't you use GrandCentral.com its free...you can register all your numbers to GC!!

From my experience with GrandCentral, it will forward your calls to "all" phones on your list "simultaneously", but not sequentially, as you seem to emphasize in your question.
As well, GC is not available in all area codes, so you will need to verify that GC has a phone number in your area code of choice. However, GrandCentral service is currently free, while in beta development phase.... so free is hard to beat...

If GC doesn't fit your bill of needs, then I would suggest InPhonex (see link through my profile).
InPhonex will provide you a phone number in most any area code of USA/Canada - more to choose from than GrandCentral.
InPhonex will forward to "multiple phones" you specify, or forward "sequentially", one phone at a time, until someone picks-up the call, or ultimately off to voice-mail.
InPhonex is a VoIP service.
But, to use InPhonex as a call-forwarding/call-hunting service, you do not actually have to have any VoIP equipment installed. Just administer the call-forwarding and call-hunting features directly from the InPhonex web administration page and you don't have to mess with any VoIP hardware issues.
InPhonex is not free, but their rates are very low and reasonable.
You can get InPhonex "Lite-LIne" for $7.95/month, which includes an area code phone number in your area code of choice. All incoming calls are included free. All outgoing and "forwarded" calls are charged at 2.5 cents/min to anywhere in USA/Canada.
I use InPhonex Lite-line as my primary VoIP home phone service and am very satisfied with it.

I'm moving to a new residence next week. I will be using the InPhonex call forwarding and hunting feature to take calls between my two residences until I renovate and sell the old residence.
