I know that we have to provide power to the modem, the router and the ATA.
And, as Jake mentioned, a phone base if one is used (or if a phone requires electricity)
(Of course the ISP should not be affected by the outage)
It should be noted that no ISP has 100% up time.
No SIP service I'm aware of does either.
I suggest reading pages 46 to 48 from
download/file.php?id=2195 ("I've heard scary stuff about VoIP 911. Isn't it unreliable?").
With the exception of the $35 fee discussed using FPL and the OBiBT Bluetooth adapter, everything else applies.
Does a good UPS battery backup system provide enough power to keep the phone working for some hours ?
APC BR1500G attached to APC BR24BPG external battery should last at least 8 (likely closer to 9) hours, depending on the modem, router, ATA, and phone being used.
I think context is important. If you're worried about your father, I would consider a cellphone for a backup for 911. Suddenly, requiring a UPS is less important than having external batteries for a cellphone, particularly if your father already has cellular service.
Even if he doesn't, it may still be possible for a deactivated cellphone to call 911.

"Can I still call 9-1-1 from a deactivated cell phone?
Possibly. In some cases, a call to 9-1-1 from a deactivated cell phone will reach a 9-1-1 operator. However, because that phone is not associated with any particular wireless service provider, the 9-1-1 operator will not be supplied with a dialable phone number. In the event of a call disruption, the call taker would not be able to call back. The operator may receive information about the cell site or cell tower that is transmitting the call, but they will not be provided with longitude and latitude coordinates."
Theoretically, 911 calls from deactivated cellphones are supposed to work in Canada. If you pop a sim card out, the cellphone is supposed search for a signal when dialing 911. I can't say I've tested dialing 911 with a deactivated cellphone. I can't guarantee a 911 call from a deactivated cellphone will work, but it should work provided you're in an area that has cellular signal coverage that the cellphone can connect to.
