Firmware

The KalliopePBX firmware follows a 4.X.Y numbering system where:

• X is the Major Version:
  • releases with an even Major Version number (4.0.Y beginning from 4.0.8, 4.2.Y, etc.) are Maintenance Releases (MR), i.e. stable versions that mostly contain bugfixes; these releases add fewer features but guarantee greater stability;
  • releases with an odd Major Version number (4.1.Y, 4.3.Y, etc.) are Technology Releases (TR), i.e. versions which introduce new features;
• Y is the Minor Version, the sequential identifier of releases within the same Major Version.

N.B.: The minimum RAM requirement for VMs is 2GB. If the RAM is below this requirement, the PBX will not start. The recommended RAM requirement for VMs with firmware version 4.9.8 or later is 4GB.

Bootloader

The bootloader is the base operating system of the PBX. It does not contain telephone features but is used to install and manage the firmware. The bootloader is updated similarly to the firmware, but it is updated in place and cannot be returned to return to a previous version. After a new bootloader is installed, the PBX will need to be rebooted (on the bootloader itself) to complete the procedure. After this, it will be possible to reboot the PBX normally on one of the available firmware versions.

Bootloader 1.1.0

This update adds to the bootloader software components usually distributed within the firmware, reducing the size of future updates. Bootloader version 1.1.0 is required for installing firmware updates starting from version 4.10 and 4.11

N.B.: There is a procedure to resolve the ERR_UNSAFE_PORT issue with Chrome and Firefox browsers. For more information on the procedure to follow (Click here)

Changes

• System:
  • K-2630: Changed the firmware update download path to fix an issue where updates sometimes failed if the RAM assigned to the Kalliope VM was limited.

Bootloader 1.0.7

This update changes the file system of the storage partition to add a journaling feature. This change helps reduce the file corruption issues present in this file system (configurations, logs, databases) that may occur in case of a power failure when the system is writing the data.

N.B. This bootloader is a prerequisite for installing firmware equal to or later than version 4.8.0.

Changes

After acquiring a dedicated license, the PBX admin will be able to assign to user groups the management of licensed video conference rooms; through the KalliopePBX web interface the user can easily view the status of each room, create a new meeting adding internal and external participants, and send invitations via email.

N.B.: the handling of issue K-3770 changes the way the phonebook is accessed via LDAP. Up until version 4.11.2 it was possible to access the dc=extensions,dc=phonebook,dc=<domain> sub-branch,dc=root anonymously, and authentication was only necessary to access the dc=system,dc=phonebook,dc=<domain>,dc=root sub-branch.

Firmware 4.11.0 (08/06/2020)

This version introduces support for a new optional module, extended third-party SIP phone support, concerning the integrated management of phones that implement some functions though non-standard SIP variants. At the moment these include some Cisco Unified IP Phones of the 79xx series that are flashed with SIP firmware, and others that share this property (e.g. 78xx).

The module enables handling of BLF (Busy Lamp Field) keys though the assigned SIP account panel and the generation of the corresponding provisioning file for the phone. Some services can also be controlled through the phone function keys (call pickup on BLF, unconditional call forward). The LDAP phonebook can also be accessed by phones for direct consultation.

Changes

• GUI
  • K-2507: In order to make the extension creation page more clear, when an account is created during extension creation there is now the option to only specify the base attributes (username, secret, and template), and the complete form will no longer be displayed.

Firmware 4.10.1 (09/11/2020)

N.B.: the handling of issue K-3770 changes the way the phonebook is accessed via LDAP. Up until version 4.11.2 it was possible to access the dc=extensions,dc=phonebook,dc=<domain> sub-branch,dc=root anonymously, and authentication was only necessary to access the dc=system,dc=phonebook,dc=<domain>,dc=root sub-branch. Starting from this version, access to both sub-branches requires authentication.

  • K-2812: Fixed a bug that caused the DND status of all extensions to be sent to clients simultaneously, which could cause the clients to be disconnected
  • K-2740: Fixed a bug that caused the a wrong notification to occur on KCTI iOS when the user made a call and cancelled it before it was picked up
• HA
  • K-2874: Fixed a bug that prevented the correct synchronization of of room status on the passive node of an HA cluster

Changes

• High Availability
  • K-247: Changed periodic cronjobs to execute only on the primary node
  • K-250: Changed periodic cronjobs to check that the resources used are active before execution

Firmware series 4.9.x (TR)

Firmware 4.9.6 (16/03/2020)

New features

• Extended the "Kalliope Hotel" module with the [Charges documentation] feature, which makes it possible to configure charges for calls made from rooms and generate a summary of the sustained costs from check-in. The reports persist after check-out and can be accessed through the "Booking log".
• Added the option to select the dial-out participants of audio conference rooms and the recipients of call campaigns from the phonebook by beginning to dial the number or the name; the system will suggest the matching contacts.

Known issues

See 4.8.0

Bugfixes

• CDR
  • K-1153: Fixed a bug introduced in version 4.8.0 that caused outbound fax calls and calls made through the click-2-call service not to be displayed in the CDR

Firmware 4.8.2 (23/12/2019)

Known issues

See 4.8.0

Bugfixes

• Multi-tenant
  • K-994: Fixed a bug present in version 4.8.0 that caused manipulation rules for calling and called numbers on outbound lines assigned to the tenants not to be applied

Firmware 4.8.0 (2/12/2019)

WARNING: This update distributes the updated certificates required by Apple's PushKit service. The certificates installed with previous versions will expire in January 2020. To guarantee the correct functioning of the KalliopeCTI mobile app for iOS after that date, it is necessary to update KalliopePBX to this version.

N.B.: In order to update the firmware to version 4.8.0, it is necessary to update the bootloader to version 1.0.7 (which is recommended even for previous firmware versions).

Known issues

For outbound lines (gateways, trunks, or terminations) with a space in their name (e.g. "Outbound line"), the outcome of outbound calls will always be reported in the CDR as "NOANSWER" even if the call was answered and its "Conversation time" attribute is not null. The current workaround is to remove any spaces in the names of all outbound lines.
