Incoming calls on the LINE port don't seem to pick up CallerID. Any ideas ???

If your OBi unit is in US, you might check "RingDelay" setting on LINE port, and make sure it has sufficient time ( > 3500ms) for OBi110 to collect caller ID.
Looks like you have similar issue as Northern.Bob with the PSTN line callerID not displaying:

Please send email to support@obihai.com with your OBi number. Support might be able to provide a new firmware to cure this issue.
