Enhanced Speakerphones for Digital Endpoints
Enhanced Speakerphones for Digital Endpoints
The following display and non-display digital endpoints have enhanced speakerphone capabili-
ties:
•
Models 8500, 8520, and 8560 digital endpoints
•
Executive, Professional, Standard, and Associate Display Endpoints
•
Axxess and Eclipse Basic Digital Endpoints
To use an enhanced speakerphone on a digital endpoint , the user establishes a call and presses
(the Special button) and then the Speaker button (or presses and enters the
Enhanced Speakerphone feature code, 310). There will be about one second of white noise at
this point. Both parties should avoid speaking during this white noise, which is used to cali-
brate echo-canceling circuitry. After the white noise, there will be a confirmation tone that both
parties will hear (except for Executive Display and Professional Display endpoint users who
will hear the tone, but the other party will not). Then the user will be connected in an enhanced
handsfree call. If the speakerphone cannot be calibrated correctly due to trunk conditions, the
enhanced speakerphone will not be enabled and the display will show CANNOT ENABLE
ENHANCED MODE.
NOTE:
It is normal for an outside party to hear a minimal amount of his or her own echo when
speaking to a digital endpoint in enhanced speakerphone mode. This is usually acceptable to
most callers on local calls and on most long-distance calls. However, on some T1 and long-dis-
tance calls involving significant delays (for example, cross-country T1 calls, overseas calls or
calls via satellite), the amount of echo may be objectionable, and the enhanced speakerphone
mode should not be used on these types of long-distance calls.
If an enhanced speakerphone call is placed on hold and then taken off hold on an Executive or
Professional Display Endpoint, it remains an enhanced speakerphone call. For all other digital
endpoints, if the call is placed on hold, the call is returned to standard speakerphone mode.
A station can only have one enhanced speakerphone call. For example, if an Executive or Pro-
fessional Display endpoint user makes an enhanced speakerphone call, puts it on hold, and
establishes another enhanced speakerphone call, the first call will be turned back into a stan-
dard speakerphone call.
A digital endpoint user can set up a conference and then, once it is established, presses the
(Special button) and Speaker (or presses and enter the Enhanced Speakerphone
feature code, 310) to have an enhanced speakerphone call in the conference.
Analog, IDS, and Wave Endpoint Speakerphones
NOTE:
The volume adjustment range of non-AIM and non-DVK analog endpoints may not be
suitable in all user environments. In such cases, Inter-Tel recommends using AIM and/or DVK
endpoints, if possible.
