Line Buttons In Hybrid/Pbx Mode - AT&T MERLIN LEGEND Release 3.1 System Manager's Manual

Telephones
ICOM buttons fall into several categories:
ICOM Ring. Use this button to make inside calls and to receive inside
and outside calls transferred from another extension. When you use an
ICOM Ring button to make an inside call, the telephone at the destination
extension rings once per ring cycle to indicate an inside call.
ICOM Voice. Use this button to make inside calls and to receive inside
and outside calls transferred from another extension. When you use
ICOM Voice to make an inside call, the user at the destination extension
hears the caller's voice on the speakerphone after a beep that replaces
ringing. (If you are using an ICOM Voice button to make a voice-
announced call and the user at the destination extension has a single-line
telephone or a telephone that does not have a speakerphone, or has
disabled voice announcements, the telephone rings just as if the call was
made on an ICOM Ring button.)
ICOM Originate Only. Use this button to make inside calls. You cannot
receive inside or outside calls on ICOM Originate Only buttons. This
type of button ensures that you always have a button available to make or
transfer a call, establish a conference call, answer a call-waiting call, or
pick up parked calls. You can program this button for either voice or ring
operation.
You can assign any combination of up to 10 ICOM Voice, ICOM Ring, and
ICOM Originate Only buttons to each telephone on line buttons 1 through 10.
The number of line buttons that you can assign to a telephone is limited only by
the number of lines/trunks in the system and the number of buttons available on
the telephone.

Line Buttons in Hybrid/PBX Mode

Because outside trunks are pooled in Hybrid/PBX mode, outside numbers are
not associated with individual telephones. SA buttons on multiline telephones
allow you to access a pool of lines and make different kinds of calls from the
same button. Other types of buttons may connect the user to pools of special-
purpose lines or to personal lines that are not pooled.
You can assign the following types of buttons to multiline telephones:
SA Ring. Use this button to make and receive inside and outside calls.
When you use an SA Ring button to make an inside call, the telephone at
the destination extension rings once per cycle to indicate an inside call.
