Caller id not working

Make sure the batteries are good and the AC adapter is plugged in and your caller ID is working on other phones. I had a similiar problem with the same unit and that was the problem. Good Luck!

Does the LCD not work at all? or do you mean that it doesn't display Caller ID information? If the LCD is completely dead, you'll need to get the phone repaired. On the other hand, if it's just the Caller ID that's on the fritz, try this: unplug the base from the power socket; remove any batteries in both the base and the handset; wait one minute; plug the base back into the wall and replace all batteries. This will reset the Caller ID so it works again. (Depending on the phone you may or may not lose settings and memorized numbers.) If this doesn't help, the problem will require a professional repair.

Try making a new recording.

Log into your TalkSwitch Management Software.
Go to Telephone Lines.
Under each incoming line make sure that Caller ID is checked.

Hopefully this will fix it for you.

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.

How to get the caller ID to work on the additional GE DECT phone handsets. You must follow these steps in the exact order :
#1 - unplug the base phone
#2 - unplug the telephone line from the base phone
#3 - remove the battery packs from the phones
#4 - wait 10 minutes. reverse the order when assembling. Put battery packs in phones, put the telephone line back in the base phone and lastly plug all phones back in.
It takes about another 10 minutes after that before all phone handsets start recognizing caller ID.

there are a very small capacitor in the board that produce low battery mesege when it get damage, but you gona need a tech to repair your phone there are another problem in your phone its not a seting problem...good luck
