Phone Display Language

Define in which language the phone’s PUI (phone user interface) menu will be displayed in. This might or might not include the device web interface. Default value is “English”. The selectable options varies per vendor/model.

Timezone

Define in which time zone your phone will be placed. “Use global Timezone” will be the one that was specified during the installation of 3CX, and can be found and changed in “Settings” → “Timezone, Office Hours & Holidays” → “Timezone”. Alternatively, each phone of an extension can be provisioned to show a specific timezone based on configuration.

Date Format

Based on the user’s preference, specify desired date format. Depending on the vendor the options range from 2 to 6 choices to display the date on the device PUI.

Time Format

Define which time format you wish to be displayed on your desk phone. 2 options are commonly available, AM/PM or 24h interval.

Phone Web Page Password

After provisioning the IP phone the web access will be locked with the given password. Passwords are set globally for all devices of an IP phone of an extension but should vary from extension to extension.

Transfer Method

This option allows you to define which transfer method (Blind / Attended) will be used when you press DSS key (BLF key for the extension that you have configured) on the desk phone.

Configure the device with “Blind transfer” or “Attended/Consultative Transfer” to control which action should be performed once a BLF key of another extension is selected during a call.

Default Ringtone

Define default ringtone that will be used on the device. Note that this ringtone will not be used if the call comes from a queue to the device. In this case the “alert info” ringer will be used which can not be set via provisioning options.

Default Queue Ringtone

Define the ringtone that will be used when calls originate from a queue.

Power LED

In this setting the admin can define what shall happen with the power led of the device and which notification shall be indicated with it. It can range from “missed calls” to “pending voicemail message”. Alternatively it can be disabled altogether.

Backlight Timeout

Most IP phones come with backlit LCD displays. In this setting this backlight is configurable as to  if it should turn on, when it should dim before turning off or if it never should turn on.

Screensaver Timeout

On a few models, certain devices also have the option to switch into screensaver mode. The time when the device shall hide its PUI and replace it with the screensaver can be set here.

Multicast Paging Ring Group

Define a Multicast Paging Group (Ring Groups → Add Paging → Ring Strategy = Paging Multicast) which will be provisioned onto the ip phones in order to be alerted when the Paging Group is called. To remove a Paging Ring Group from an IP Phone, set the option to Off.
