Page Field Descriptions
Description
Specifies the phone system manufacturer, model and if
applicable, the integration type.
Type the appropriate integration options for the switch
installed. Valid integration options are listed in the following
table.
The Positive voice detection threshold is a threshold that
triggers Positive Voice Detection from the received audio. It
is a SW DSP detect function that does all the tone detection.
If there are more than 2 frequencies detected and if the
power levels goes above certain threshold PVD is reported.
For example, normal DTMF for in-band dialing has only two
frequencies, as do most of normal call progress tones. If
there are 3 or more frequencies, the system checks if this is
actually a human speaking. The PVD value determines what
amplitude and volume level of frequencies must be to be
interpreted as speech rather than static noise.
Type a floating point value for the threshold.
Description
Enables the messaging system to obtain enhanced caller ID
information on all calls and offer it to subscribers when they
retrieve their messages. This information might include the
name and phone number.
Optional parameters <x,y> indicate the minimum and
maximum number of seconds that the messaging system
waits for caller ID information from the phone system before
answering a call. Valid entries are x = 0
Typing CID=0,0 enables return calls to internal extensions
only.
Special dialing sequence used by the messaging system to
return to the caller after the call is transferred to an internal
extension and a subscriber with call screening rejects the
call.
Specifies the dialing sequence to use immediately after the
CR. For example, CR,,, tells the system to pause for 3
seconds while the caller is automatically reconnected.
Use this setting only when you want the return sequence for
rejected calls to differ from the return sequence for
unanswered calls.
