atl Telecom FAQ’s - click + for solution

Ensure you are using both the cords that were supplied with the telephone, i.e., the Line Cord and the Handset Cord, other cables may not work, even ones from other Berkshire products, they may look similar but the pin-outs may be different.


Ensure the wall socket is working and that it’s an analogue type socket not a digital socket, if you have a fax line try it in that socket or if you have a known working socket try the Berkshire in that socket to test that the telephone is functioning correctly.

To divert phone calls to a different extension you will need to get a divert code from either your line provider or if you work behind a switchboard ask your switchboard supervisor. The code will be the same for you and all your other phones that work behind the switchboard.

This is possible but you will need a feature code / facility code that has been set up on your switchboard. Ask your switchboard supervisor about Group pickup / Direct pickup options.
