Hello Andrew and welcome to our forum. You have come to the right place for support.

Identifying each extension is fairly simple. Just dial 0 from each extension and view the calling extension number on the receiving display.

To call them, just dial the extension number.

To transfer, just hit the Tran/con button while the caller is on the line and dial the desired extension.

My memory is quickly failing on this system, but I thought that might get you started until someone with better knowledge of your system can step in to assist.
