Are you planning to add a battery backup for OBI devices?
pjs344:
Most internet/voip providers have their devices with a battery backup. I have not seen any standalone voip provider offer any voip devices with either an internal or external battery backup for when the power goes out. Most cable, DSL, Wimax and 3G/4G hotspot providers are on backup system. So there service does not go down when the local power goes out in the area. Not everyone can afford a Cell phone and that is why they use a free or low cost voip provider.

You could look at a small UPS device like one MFG by CyberPower that has a small foot print and would keep you up long enough to complete a call and protect if from outages and spikes. You could add your modem and router to keep your Internet connection up for a time. I think they have one at the 35.00 mark, but maybe it's a little more.

Mine is protected by an UPS which services all of the computer equipment in the area where it is located. It's probably good for an hour. After that, I'd probably have my generator online if I were there.
When I considered cutting the cord to the landline and replacing it with a VoIP solution, a protracted power outage was probably the most serious scenario: Not only would it likely be widespread, but it will kill my ISP in about an hour as well. However, in a pinch I have my cell phone as a backup.
I have a friend, BTW, who is running his OBi200 off a 12.6V trickle-charged battery. So far, it's run fine.

That's actually a good idea, as long as all the other equipment upstream of the OBi is also running on that battery :o
At one time, I actually sold UPSs for data centers and branch office use. I've got 5 of them at home, spread all over the place, since we get power outages here every winter. The problem is, that their inverters (the circuitry that converts the battery power to AC) aren't very efficient, and they waste a fair amount of battery power as heat. Ideally, they're just intended to ride out short outages, or until a generator can kick in. Skipping the DC-->AC-->DC conversion by hooking the ~12VDC networking gizmos up to a AGM lead acid battery (or bank of several batteries) is a more efficient solution, and it's what the telcos did for decades, running most everything on 48VDC and rooms full of batteries.

The following devices are connected to my Back-UPS 550 http://www.amazon.com/APC-BE550G-Back-UPS-8-outlet-Uninterruptible/dp/B0019804U8 (Shipping Weight: 13.7 pounds):
- Cable modem/router/wifi
- Another router
- Obi200
- Panasonic phone base station
I was disappointed that this UPS lasted only 45 minutes in my test.
I recommend buying a larger UPS or supplementing similar UPS with an external battery.
