Call Log symbols

[Shorefisher]

I have searched various forums for explanations of the Stylo 3 call log arrows and found conflicting opinions and never a complete answer.
I would very much appreciate explanations of these arrows:

Arrow pointing left
Arrow pointing right
Arrow bending upward
Arrow bending downward
Red Arrow
Green Arrow

This information is not in the manual.

Upward, outgoing calls,
Downward, incoming calls.
Green, answered.
Red, missed call.
Left and right, no clue.
I hope this helps
