Nortel M7310 I have a Nortel M7310 with Caller ID, is there any way to scroll through and look at the most recent incoming calls?

Your M7310 phone does not have caller ID. The phone system can have caller ID and there are a few different options you could have for phone system and caller ID packages. You should try to find out which Nortel phone system you have and possibly what type of Caller ID unit.

I suspect you cannot do what you are looking for because as I mentioned, the phone itself does not have caller ID and only displays what the phone system tells it to. It is more complicated for a caller ID system to store a list of previous calls when you have multiple lines and multiple phones. Would you want to see a list of every call that has come in, just the calls that rang at your station or just the calls that rang and you answered at your station.... BUT... this may be ansered in a user guide specific to your phone system or your caller ID interface.

Yes you can  turn on Call log on your system,specifically if you have caller ID LS/DS trunk cards.

System need to have Call log turn on, providing you have CID trunk card then this should work
