INTER-TEL AXXESS MANUAL VERSION 11.0 – May 2008
12.13 Executone IDS Keyset Models 160, 64, 32, 18, and the Wave phones have a speaker
and a microphone for handsfree intercom reply. They do not need any additional speakerphone
system resources. Executone IDS Keyset Model 12 keysets and the Agent Terminal have only
a speaker. They do not have a microphone.
12.14 Each time a speaker/microphone keyset user presses the Speaker button while on hook,
the standard switched speakerphone is activated, and the DSP resource (DKSC-16/DKSC-16+
or Options Card) is assigned to that phone for the length of the call. If a phone user requests
the speakerphone function when DSP 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 speakerphones
are unavailable, the call will be forced into a monitor-only mode. The user will hear the other
party but will not be allowed to transmit to them. In this mode, the user's button will
MUTE
be lit, and the display shows NO SPKRPHN AVAIL COME OFF HOOK. Pressing the lit
button will result in a burst of reorder tone; you must lift the handset to speak.

Enhanced Speakerphones for Digital Phones
NOTE:
In general, IP phones and phones that connect to IP calls (i.e., calls that are routed
through an IPRC) cannot enable enhanced speakerphone mode. However, sometimes the sys-
tem may not detect that a call is connected over an IP network. If this occurs, the system may
allow users to enable enhanced speakerphone mode, which will affect the call quality.

12.15 To use an enhanced speakerphone on a digital phone, the user establishes a call and
∞ ∞
presses or and then the Speaker button (or presses or and
SPCL SPCL
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.) This
white noise is used to calibrate the echo-canceling circuitry. After the white noise, there will be
a confirmation tone (Executive Display and Professional Display Phone users will hear the
tone, but the other party will not. On a Standard Display, Associate Display, Axxess Basic Dig-
ital, Eclipse Basic Digital, Model 8520, Model 8500, or Model 8560 Phone, both the user and
the other party will hear the tone.) 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 phone in enhanced speakerphone mode. This is usually acceptable to
most callers on local calls and on most long-distance calls. However, on calls established using
an IP Networking Module or IPRC and some T1 and long-distance 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, including those connected via an IP Networking Module.
12.16 If an enhanced speakerphone call is placed on hold and then taken off hold on an Exec-
utive Display and Professional Display Phone, it remains an enhanced speakerphone call. If it
is placed on hold at a Standard Display, Associate Display, Axxess Basic Digital, Eclipse Basic
Digital, Model 8520, Model 8560, or Model 8500 Phone, the call is returned to standard speak-
erphone mode.
12.17 A station can only have one enhanced speakerphone call. For example, if an Executive
Display or Professional Display Phone 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 standard speakerphone call.
