Inter-Tel Digital Endpoints
The following paragraphs describe the features supported by Inter-Tel endpoints. Throughout
this guide, the term “Inter-Tel endpoint” refers to full-feature endpoints manufactured and sold
by Inter-Tel. The term does not apply to industry-standard single line DTMF endpoints.
Display and Nondisplay Digital Endpoints
The following display and non-display digital endpoints have a built-in speaker and micro-
phone that allow the user to answer intercom calls handsfree, dial while on-hook, monitor
calls, and listen to background music.
• Models 8500, 8520, and 8560
• Executive Display
• Professional Display
• Standard Display
• Associate Display
• Axxess Basic Digital
• Eclipse Basic Digital
These endpoints can be programmed in individual endpoint programming to be allowed to use
system resources for standard and enhanced speakerphones. Enhanced mode allows for full-
duplex operation over a limited volume range (the range depends on trunk characteristics, typi-
cally the range is 1-3). Enhanced speakerphones are explained in the following section.
If a user presses the Speaker button while on-hook, the standard switched speakerphone func-
tion is activated and the speakerphone resource is assigned to that endpoint for the length of
the call. If a user requests the speakerphone function when speakerphone resources are not
available, the user will hear reorder tones, and the display will show
NO SPKRPHN AVAIL
STAY OFF HOOK
.
If the user attempts to change to the speakerphone and hangs up during a call when speaker-
phones are unavailable, the user will be forced into a monitor-only mode. The user will be able
to hear the other party but will not be allowed to transmit to them. In this mode, the user’s
button will be lit, and the display shows
NO SPKRPHN AVAIL COME OFF HOOK.
Pressing the lit button will result in a burst of reorder tone; lift the handset to speak.
On certain handsfree-to-handsfree intercom calls, voice volume levels may cause feedback to
occur. If this happens; one station user should pick up the handset. Two display endpoints can-
not be in enhanced mode while on a call together; one endpoint must be off-hook to allow the
other endpoint to enter enhanced speakerphone mode. If both endpoints are on-hook, there is
no benefit to having one endpoint in enhanced mode.
