Comcast to Start Charging For XFINITY Voice Backup Batteries → What battery?

I know there is a place for one but mine did not come with a battery and when I asked about it I was told basically that if we loose juice so do they hence no need to include...

Pretty much true. They also take a lot longer than commercial utility power to get back online.

File a FCC complaint, they are required to provide the batter for the eMTAs. This isn't MagicJack that gets away with it being non carrier grade VOIP. The battery backup ability was the whole reason the FCC permitted Cable VOIP.

ok but what difference does it make if/when they don't have power either. additionally i don't use their voip service so really a non-issue for me personally.

The plant is designed to have backup generators to enable the phone system to still get a signal. If Insight loses power at their office, odds are that the whole town is and you'll have bigger issues to deal with.

Not Comcast. Their nodes are out in the field, and there are no backup generators there...
