Inter-Tel Digital Phones
The following paragraphs describe the features supported by Inter-Tel endpoints.
Display and Nondisplay Digital Phones
The following display and non-display digital phones have a built-in speaker and microphone
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 phones 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 below.
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.
Executive and Professional Display Speakerphones
Each Executive and Professional Display phone has a built-in, integrated speakerphone that
allows on-hook dialing and handsfree operation on outside calls and inside (intercom) calls.
The speakerphone can be used in standard mode or in enhanced mode which 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 on the following page.
The Executive and Professional Display phone’s speakers can also provide background music
if an external music source is installed and the speaker is used to receive pages.
NOTE
Throughout this guide, the term “Inter-Tel endpoint” refers to full-feature endpoints/
phones manufactured and sold by Inter-Tel. The term does not apply to industry-
standard single line DTMF phones.
NOTE
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 phones cannot be in enhanced mode while on a call together; one
phone must be off-hook to allow the other phone to enter enhanced speakerphone
mode. If both phones are on-hook, there is no benefit to having one phone in
enhanced mode.
