#anything# won't reset that. What do you want to get? From the idle phone, press PROGRAM and dial 19x where x is 0 for none (probably someone dialed 190), 1 for idle line, 2 plus a number 01-36 for a specific line, and 3 for intercom, followed by SAVE or ENTER.
System commands start with *xxx for resets. ie *790# erases some extension features like call forwarding.

Just want to get back to not having to press the "Intercom" button for a dieltone, i.e. for an internal call, just dial the extention, and for external simply '0' will get an outside line.
