As Peter suggested, the UPS was just there to handle short power 'bumps'. It all depends on your tolerance for service interruption for your intended use. If you're OK with a PC and an FXO card for hardware, then Peter's solution is the one I, personally, would recommend.
I haven't looked too deeply at how Asterisk writes voicemail messages. If you lost power while a message was being recorded, I think that message would be lost because it's not actually recorded directly to the message store but to at temp area. All previous messages should be OK though in the scenario you outlined. Dave On 6/7/07, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote:
Dave, Thanks for the advice. Regarding option 1 - why is the UPS required? If messages where written to a journal-ed file system, would a power failure negatively impact Asterisk? Desired configuration: • one PC, one FXO card (or ATA device), no UPS. • App and OS on read-only file-systems • Greeting and incoming messages stored on a JFS file-system Sequence Event: Asterisk is capturing an incoming message. Message is written to a JFS file-system Next Event: power drops half way through the message Next Event: Power resumes Next Event: OS and App reload off read-only FS Next Event: Asterisks loads state information for answering machine off JFS file-system. (Any issues?) Next Event: Remote user dials in and requests message playback. Request granted. (Any issues?)

If you're willing to spend a couple hundred bucks, then one of several Asterisk configurations would work. You could buy a cheap PC for $50, an FXO card for $30, a UPS for $70 and you with a bit of work, you're in business. That would only give you a short amount (maybe 10 minutes) of runtime in a power outage. You could get a WRT54GL, load Asterisk on it, and hook it up to an ATA and that would use much less power. You might do that for close to $200. There are tonnes of other configs that can work. As for non-asterisk solutions, you're looking at pretty basic features, other than the long message length. Still, I'm sure if you looked hard enough you'd be able to find a consumer grade, solid state answering machine to do what you want. Good luck.

I would like a "turnkey" answering machine that can deliver a long greeting (up to 20 minutes), capture messages for play back, and handle unexpected power outages.Remote greeting configuration and message play back is required.Extensions are not needed.The system will monitor one analog phone line. The ideal answering machine is inexpensive, low maintenance and unlikely to make outbound calls (i.e. no dial-out.) What's the best way to proceed?
