What module do I need to purchase to get called ID on my M7310

This feature requires a class trunk card in the phone system to pass Caller ID.

You must have latest software to have Caller ID
You must have a Caller ID line card
Caller ID must be programmed on the phone to allow it
Caller ID signal from carrier is sent between 1st and 2nd call

FYI on the fax: Analog ports (ATA's) on the Norstar system do not show Caller ID, instead you would need to use a line share device that supports caller id such as the STICK.

The M7310 will display "Message for you" on the LCD screen when you have a message, provided that the Voice Mail system is configured to provide indication to the phone.

The exact steps to do this will depend on what kind of Voice Mail system you are using on your Nortel PBX.

This can happen if you transfer a call from outside to another outside line, or if somone has their phone set to forward to an outside line (like a cell phone)

Also, if you do not have "Disconnect Supervision" on your trunks and "Clear on Disconnect" (COD) set by the phone company, this can happen.

This sort of fix is usually done by a telephone professional, but you can do it if you specify the model number of the PBX that you have.

To clear the lines, you either need to reboot the PBX or temporarily disconnect the lines from the PBX.

You need a CI trunk card not a LS/DS trunk card for caller id.

that's a setting within the PBX system. See if you can find your user manual, or contact a business telecom company to see if they can provide you a copy.

In system programming your station needs to set caller id to Y.

i am assuming the system accept caller id. Other stations are working.

Try FEATURE 6 6 and the extension of the phone that you want to page to.

When you say you are the one responsible for the programming, are you referring to programming the "physical phone" or the PBX and line cards and system functionality?

You should have an extension on your phone. Has that extension for example 222 been translated at the PBX to ring on a direct number -> (xxx) 555-1222

Or by what you are describing, you are more looking at having "shared lines" that ring in multiple locations simultaneously, and once picked up somewhere a "line lock" should be in place?

First off seven to nine you do not use an external cid unit for norstar systems. Make sure you have a caller id card in the main ksu or key service unit( the phone cabinet) It should say CI on it. If the card says DS then you do not have a caller id card on the system and will need to exchange it for one. Then the system phones will have to be programmed for cid.
