It's been a few years since I programmed a 624, but here goes.
IIRC the 624 selects lines in 1,2,3 order vs. the 824's 321. Dial "9" from the intercom and you can verify this.
The system has 3 modes of operation when it comes to outside line access, No preference (gives you intercom dial tone) Idle line preference (gives you the same as if you dialed "9", and specific line preference.
From the phone, do not pick up the handset but press PROGRAM or use the set switch to program, dial 1 1 for none, 1 2 for idle, or 1 3 x for a specific line. Any of those commands would be followed by STORE.
Put the system back in SET or press the PROGRAM button to exit.
With any line preferenc, you have to press Intercom to dial internally or page. If your specific line is busy, you won't get anything when you pick up the phone or press SP PHONE. It also disables Last Number redial if the line is busy.
Did I mention that I don't use it :-) Of course, I don't use the 624 either.
