Hello,
There is this known issue with state "Off-hook" being activated after using for a while. There is this temporary fix with shut/no shut of the port but need a permanent solution.

Tried a combination of what others have suggested on other threads but it didn't work.
Old Config for this port was:
voice-port 0/2/1
trunk-group AT_FXO
connection plar opx 445
description AT Group
caller-id enable
!
New config based on other recommendations:
voice class custom-cptone MYTONE
dualtone disconnect
frequency 425
cadence 350 350
!
voice-port 0/2/1
trunk-group AT_FXO
supervisory disconnect dualtone mid-call
supervisory custom-cptone MYTONE
connection plar opx 445
description AT Group
caller-id enable
!
