Enhanced Speakerphone Mode - Inter-Tel 8520 User Manual

Enhanced Speakerphone Mode

The Enhanced Speakerphone Mode improves transmission quality while on a speak-
erphone call over a limited volume level range (typically the range is 1 to 3).
NOTE:
To use this feature, the system administrator or installer must program your
endpoint for Enhanced Speakerphone Mode.
To enable enhanced speakerphone mode while on a call:
EITHER, Press
OR, Press
when you end the call.
There will be about one second of white noise while the speakerphone circuitry is cal-
ibrated to the call. (Both parties should avoid speaking during this white noise.) If the
speakerphone cannot be calibrated correctly, displays show CANNOT ENABLE
ENHANCED MODE.
NOTE:
Two display endpoints cannot be in enhanced mode while on a call together;
one endpoint must be off-hook to allow the other endpoint to enter enhanced speaker-
phone mode.
ALSO:
On some long-distance calls, the outside party may hear his or her own echo
when speaking. If the amount of echo is objectionable, do not use the Enhanced
Speakerphone Mode.
