Never used, thought we would try, did so 2 day ago.
iP5 w/ iOS8 signs into the App store fine but not FT.

FaceTime says: FaceTime Activation could not Sign In

Two different iP5's both iOS8.x
Different networks.
Turned off iPhone overnight last night.

Read this, no help:

If you can’t turn on or sign in to iMessage or FaceTime on your iPhone - Apple Support

To use either iMessage or FaceTime, you need to activate them on your iPhone. If you see an error message when you try to activate, follow these steps.

Perhaps iOS8 is no longer supported?

Time to shake the cobwebs out and take the update.

Download Google Duo, better video quality and UI.

And it comes with free data mining included!

iOS 8.1 has some advantages, even over 8.3. For one I can access data within Apps with iMazing, Apple took away access w/ 8.3.
The iP5 runs great on 8 and doubt it would update to any 64bit iOS (would need an iP5s).

I downloaded Duo on a Mac then tried with the iP5 and it said there was no version for this device (often one can download anolder version of an app if one first purchases on a Mac that has iTunesprior to v12.7.
Google Voice app (32bit) - will no longer let one sign in. Hence my thought about FT.

I did more research and found this which would indicate iOS8 and earlier are no longer supported:
