button at any time to return to your original call and disconnect the second call. If you wish to keep the second call, you must remember to place it on hold before returning to the original call. You can switch between lines as much as you want during the course of a call. Always remember to place your current call on hold before seizing another line, or you will disconnect your current call.

6.3.3.Answering a call on another line

While having a conversation on one line, if a call comes in on another line, its line lamp will begin flashing and a double ring will sound every 15 seconds. If an incoming call is coming in on a line that is set to “ringer off”, the alerting ring will not sound.

You may answer the call by pressing the flashing LINE button. Remember to put the first call on hold before answering the incoming call, or the first call will be disconnected.
