I am tring to figure out how to program extensions on our kx-t7737 phone.
A 773x phone has 24 buttons, 12 are lighted and 12 are Feature. If you want to reassign some of the lighted buttons as extension buttons on the phone, you can press PROGRAM 1 + ext no STORE and that will give you a busy indication whenever that extension is off hook.
You can program the right side buttons to speed dial the extensions by just pressing PROGRAM ext no STORE. It will dial the extension when you press it if you have intercom dial tone.
How the button behaves is dependent on which system the phone is attached to. In a TA, you have to start with dial tone on the intercom. In a TAW/TDA you don't.
