Abstract
A method of operating a multi-line telephone apparatus includes, when a phone line switch (140) is actuated, taking a phone line off-hook when the line is on-hook and bringing the phone line on-hook when the line is off-hook. When the phone line is off-hook and a hold switch (164) is actuated, a hold condition is placed on the phone line when the line is not on hold and removed when the line is on hold. When a phone call is established on a first phone line and a conference switch (160) is actuated, a second phone line is brought off-hook and a conference call connection is established. A common conventional method of making a conference call, which includes actuations of hold switch (164) and phone line switches (140, 142), is retained.
