8.1.5 Call Waiting
The Call Waiting feature enables FXS modules to accept an additional (second) call on
busy endpoints. If an incoming IP call is designated to a busy port, the called party hears a
call waiting tone (several configurable short beeps) and (for Bellcore and ETSI Caller IDs)
can view the Caller ID string of the incoming call. The calling party hears a Call Waiting
Ringback Tone. Called party can accept the new call, using hook-flash, and can toggle
between the two calls.
To enable Call Waiting:
 Set ‘EnableCallWaiting = 1’.
 Set ‘HookFlashOption = 0’.
 Set ‘EnableHold = 1’.
 Define the Call Waiting indication and Call Waiting Ringback tones in the Call
Progress Tones file.
 To configure the Call Waiting indication tone cadence, modify the following
parameters: ‘NumberOfWaitingIndications’, ‘WaitingBeepDuration’ and
‘TimeBetweenWaitingIndications’.
 To configure a delay interval before a Call Waiting Indication is played to the currently
busy port use the parameter ‘TimeBeforeWaitingIndication’. This enables the caller to
hang up before disturbing the called party with Call Waiting Indications. Applicable
only to FXS modules.
Both the calling and the called sides are supported by FXS modules; the FXO modules
support only the calling side.
8.1.6 Message Waiting Indication
Mediant 1000/FXS modules can accept an H.450.7 message that indicates on waiting
messages. Users are informed of these messages by a stutter dial tone. The stutter and
confirmation tones are defined in the CPT file (refer to Section 16.1 on page 367). If the
MWI display is configured, the number of waiting messages is also displayed. If MWI lamp
is configured, the phone’s lamp (on a phone that is equipped with an MWI lamp) is lit.
To configure MWI set the following parameters:
 EnableMWI
 StutterToneDuration
 MWIAnalogLamp
 MWIDisplay
 CallerIDType (determines the standard for detection of MWI signals)
 ETSIVMWITypeOneStandard
 BellcoreVMWITypeOneStandard
8.1.7 Name Identification
The H.450.8 service enables Mediant 1000 gateways to send and receive the calling party
name and its presentation (allowed or restricted). To configure name identification set the
EnableNameIdentification ini file parameter.
