Logging in and out at a phone can be done either using system short codes or programmable buttons.

• The default system short code for logging in, is *35*N# where the user replaces N with their extension number and log in code separated by a *. This uses the short code feature ExtnLogin. If the user dials just a log in code as N, it is checked against the user with the same extension number as the extension's base extension number.

• The default system short code for logging out is *36. This uses the short code feature ExtLogout.

• The ExtnLogin and ExtnLogout features can be assigned to programmable buttons on suitable Avaya phones. The ExtnLogin button prompts the user to enter their details.
