Prolog information
This tab contains settings that are applicable to analog extensions. These extensions are provided by ports marked as POT or PHONE on control units and expansion modules.
These settings are not mergeable. Changes to these settings will require a reboot of the system.

Equipment Classification:

Field
Description
Default = Standard Telephone.
Only available for analog extension ports. Note that changes to this setting are mergeable.
Quiet Headset
On extensions set to Quiet Headset, the audio path is disabled when the extension is idle. Ringing is presented in the audio path. Caller ID is not supported on the phone.
This option can be used with analog extensions where the handset is replaced by a headset and all audio, including ringing should be through the headset.
Since the audio path is disabled when idle, the Quiet Headset extension cannot dial digits to make calls. Therefore, to make and answer calls this option is typically used with the user Offhook Station (UserTelephonyCall Settings setting which allows the extension user to make and answer calls using applications.
Paging Speaker
Used for analog ports connected to a paging amplifier. This extension will present busy and cannot be called or be used to make calls. It can only be accessed using Dial Paging features.
When using a UPAM connected to an analog extension port, the extension's Equipment Classification should be set to IVR Port rather than Paging Speaker.
Standard Telephone
Use for normal analog phones.
Door Phone 1/Door Phone 2
These two options are currently not used and so are grayed out.
IVR Port
Used for analog ports connected to devices that require a disconnect clear signal (a break in the loop current) at the end of each call. When selected the Disconnect Pulse Width is used.
FAX Machine
If fax Relay is being used, this setting should be selected on any analog extension connected to an analog fax machine. This setting can also be used with SIP trunks.
MOH Source
If selected, the port can be used as a music on hold source in the SystemTelephonyTones and Music settings. An extension set as a music on hold source cannot make or receive calls. The audio input can be monitored through the extension music on hold controls.
A suitable interface device is required to provide the audio input to the extension port. It must look to the system like an off-hook analog phone. For example, a transformer with a 600 Ohm winding (such as a Bogen WMT1A) or a dedicated MoH device with a 600 Ohm output designed for connection to a PBX extension port which is providing loop current can be used.

Flash Hook Pulse Width

The following options are only available for analog extension ports. They define the length of loop break that will be considered a time break recall (TBR) signal.
Field
Description
Use System Defaults
Default = On
Use the default values appropriate to the system's locale. Refer to Avaya IP Office Locale Settings.
Minimum Width
Range = 20 to 2540 milliseconds.
Minimum hook flash length used if Use System Defaults is not selected. Shorter breaks are ignored a glitches.
Maximum Width
Range = 30 to 2550 milliseconds.
Maximum hook flash length used if Use System Defaults is not selected. Longer breaks are treated as clearing.
Disconnect Pulse Width
Default = 0ms. Range = 0 to 2550ms
This setting is used with analog extensions where the Equipment Classification above has been set to IVR Port. It sets the length of loop current break used to indicate call clearing.

Message Waiting Lamp Indication Type

Field
Description
Message Waiting Lamp Indication Type
Default = None
Allows the selection of the message waiting indication (MWI) mode for analog and IP DECT extensions. The options are: On (See below), 51V Stepped, 81V, 101V (Phone V2 and IP500 Phone base cards), Bellcore FSK, Line Reversal A, Line Reversal B.
If the option Restrict Analog Extension Ringer Voltage is selected (System | Telephony | Telephony), the MWI options are restricted to: Line Reversal A, Line Reversal B or None with the default Line Reversal A.
On defaults the message waiting indication setting as follows based on the system locale:
Setting
Locale
51V Stepped
Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Japan, Korea, Mexico, New Zealand, Peru, Russia, Saudi Arabia, South Africa, Spain, United States, Venezuela
101V on Phone V2 modules and IP500 Phone cards, otherwise 81V.
Bahrain, Belgium, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, Iceland, Italy, India, Kuwait, Morocco, Netherlands, Norway, Oman, Pakistan, Poland, Portugal, Qatar, Singapore, Sweden, Switzerland, Taiwan, Turkey, United Arab Emirates, United Kingdom

Hook Persistency

Field
Description
Hook Persistency
Default = 100ms. Range = 50 to 255ms.
Sets the minimum time the extension needs to be off-hook before the system treats it as off-hook and applies any off-hook features. For example dialing timers or hot-dial short codes.
Shorter periods of off-hook time are ignored.
