To place the original call on hold and connect the handset to the calling
party:
• Press + to toggle the handset between the two calls
• Press END CALL to terminate the original call and connect the
handset to the calling party
To store a number for later callback:
Note: If the word Messages appears on the handset Services display,
one or more calls have been stored.
• Press # while the handset is still ringing
• The return phone number will be stored with a number to identify
it for later callback
To recall a stored number for callback:
Note: If a callback number includes an extension, the user must note
the extension number prior to initiating the callback sequence, as
the extension number will no longer be displayed on the callback
screen.
Note: There are three types of aircall numbers: STATION, where a
number is assigned to each handset; AIRCRAFT, where a
number is assigned to the aircraft; and PERSONAL, where a
number is assigned to individual customers via GTE Airfone
cards. The difference between them is the handset activation
process. Calls to any aircall number are initiated from the
ground in the same manner.
• Press + to activate the handset (if applicable)
• From the main menu, press 8 to select the Aircall Menu
• Press 2 for AIRCRAFT, 3 for STATION, or 4 for PERSONAL to

numbers

to the ground party at that number
