Important Note: This is the PSTI ready release for the UK

Important Note: The M56 handsets require the M500 base(s) to have firmware version 1.14.4 or higher. Using M500 firmware prior to version 1.14.4 will result in reduced functionalities. 

Important Note: 

• Please make sure you read ALL of the information below before installing the software on your device.
• Please install and test the software in your environment before mass deployment.
• We encourage you to read and follow our security advisories.

Starting with firmware version 1.14.4, we've simplified the firmware upgrade process by providing the M500 unified firmware image (M500-x.x.x-unified.img), which includes the firmware for the base station, handset, and cordless deskset in one file. This is the only file required to update all devices within the M500 family of products.

To utilize the unified firmware image, configure provisioning.firmware_url to point to the unified image. Ensure that provisioning.handset_firmware_url and provisioning.cordless_deskset_firmware_url are set to null using the following configuration:

provisioning.handset_firmware_url = %NULL
provisioning.cordless_deskset_firmware_url = %NULL

Alternatively, though not recommended, if there is a need to use a different firmware version for the handset or deskset, you can update provisioning.firmware_url , provisioning.handset_firmware_url and provisioning.cordless_deskset_firmware_url with different versions of the individual firmware images (M500-x.x.x.img, M55-x.x.x.img, and M58-x.x.x.img, respectively).

PSTI UK ready

M56 shares the same firmware image with M55. The following M55's properties are applicable to M56 as well:

• Firmware image name: M55-x.x.x.img
• WUI: Servicing → Firmware Upgrade → Auto Upgrade → Handset Firmware URL
• WUI: Servicing → Firmware Upgrade → Manual Upgrade → Handset File name
• WUI: Status → Cordless Upgrade Status → Handset Version column

M56 has these unique functionalities:

1. FLASHLIGHT

For the M56 handset, added the Flashlight function to the middle softkey to the following menus:

• Main menu (displayed when pressing MENU/Confirm key when handset is idle)
• Offhook menu (displayed when pressing MENU/Confirm key during an active call)
• Menu (displayed when pressing MENU/Confirm key on predial screen)
• Insert from (displayed when pressing MENU/Confirm key during transfer setup or conference call setup)

Added the PFK type "Torch" to the Type list of the WUI page System > Device Preferences > M56 Programmable Keys > PFK. The "Torch" type can only be selected for M56 programmable keys.

The flashlight LED on the side of the M56 handset can be turned on/off by:

• pressing a PFK type assigned as "Torch"
• pressing the MENU/Confirm key, and then pressing the Flashlight softkey (when handset is idle OR during predial, active call or transfer/conference call setup).

When the flashlight LED is on, a "flashlight" icon is displayed at the top of the M56 idle screen. 

2. VIBRATION

The M56 handset can be configured to vibrate when it receives:

• first incoming external SIP call
• incoming internal SIP call
• alarm-initiated emergency call

Vibration will be disabled if the M56 handset is in low-battery status.

A new Vibration menu option has been added to the M56 Handset Settings → User Settings → Audio → Ringers.

• Mode: Off, Vibrate only, Vib then ring (vibrates only for first 10 seconds, then vibrates and rings), Vib and ring
• Level: Low, Mid, High (intensity of vibration)
• Scheme: Intermittent (vibration on 2s, off 0.8s repeatedly), Continuous

If vibration is on, the vibration icon is displayed at the top of the M56 idle screen. 

Vibration options are related to enable / disable ringer, and there is interaction between them.

1. If "Vibrate only" is selected, "Silent Ringer" (PFK) option would be enabled (→ mute ringer during incoming call ).
2. If "Vibrate then/and Ring" is selected, "Silent Ringer" (PFK) option would be disabled.
3. If "Vibrate only" is selected, and user selects Ringer Volume (not equal to zero) to enable ringer, Vibration mode would change to "Vibrate then Ring".

Please note: the following "Ringer Off" conditions would cause no ringer during incoming call, no matter what the Vibration options:

• Ringer Vol = OFF
• Silent Mode = Enabled
• "No Ringer" = Selected (per Account)
• "Silent Ringer"(PFK) = Enabled

 3. ALARM

A new WUI page SYSTEM > Alarm to support the M56 Emergency alarm function.

In a dual-cell system, this page is only displayed on the WUI of the primary base station.

Handsets/Desksets can now send a multicast page to an external party. Handsets/desksets in a paging group can now receive a multicast page from an external party.

Updated the WUI page SYSTEM → Paging Configuration to add the Multicast section.

In a dual-cell system, this page is only displayed on the WUI of the primary base station. 

Added the following new parameters:

When a handset/deskset receives a multicast page from an external party, the name of the caller is shown as "External", and the and icons are displayed on the handset/deskset screen.

If a handset/deskset fails to initiate a page on a paging group because another handset/deskset is already paging on that same group, the message "Paging Group Busy" appears on the handset/deskset screen.

Handset/Deskset wallpaper and theme are now configurable via the WUI or provisioning.

Added a new parameter (default value: off/disabled) to allow the user to enable/disable the header.
