Lines are accessed by pressing a line key. I verified that each line key on each set was programmed the same (key 01 - L01 etc).

Before the changes, the system was set up for 3 hunting lines on keys 1-3, & then 2 outbound only lines on keys 4&5. As the 2 new lines were added to the hunt group, the customer wants them to appear on keys 4&5 with the outbound only lines on keys 6&7.

Do you know if there is a "private line" feature in this system & if so could it cause me to get the "error" display if some other phone tries to access it?
