I am using Obi110. I have a POTS that has caller ID. When connected to the phone directly the caller ID worked properly. However when connected to OBI caller ID did not show up on the phone AND the call history.
I use all default settings but I also tried different settings. I am in Canada.
Physical Interfaces -> PHONE Port -> CallerIDMethod : FSK(Bell 202)
Physical Interfaces -> PHONE Port -> CallerIDTrigger : After First Ring
Physical Interfaces -> PHONE Port -> CallerIDEnable : (checked)
