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.
