### Button Module (SBM24) on the 9630

Use the 9630 Station form to enable the SBM24 Button (Expansion) Module and administer Call Appearances as primary appearances, bridged appearances, or busy indicators.

If the SBM24 Call Appearance corresponding to the CM call-associated display message or dialed-digits string is not visible because the user is not on the Phone screen, the telephone Top Line displays the call-associated display message or dialed-digits string.
