Out-of-box firmware upgrade

At present, no such upgrade is enforced. This software release introduces the capability for future needs. The following description explains how it will work if utilized in the future.

Out-of-box firmware upgrade feature potentially resolves onboarding issues caused by lower firmware version on the phone.

Upon initial onboarding, if the phone fails to register with any calling system through Zero Touch Provisioning, an automatic firmware upgrade will start to install the minimum required firmware version. Once the update process is complete, the phone will reboot and continue the out-of-box provisioning process.

See the following list for the specific conditions that trigger an auto firmware upgrade:

  • The phone is in the initial onboarding process
  • The phone has failed to register through DHCP or DNS-SRV
  • The phone's MAC address isn't provisioned in CUCM server or Cisco Device Activation (CDA) service
  • CDA service has identified that the phone is running a firmware version that is lower than the required one

Changes in the Settings menu

This release includes the following changes in user experience:

  • About this device

    The phone's IP addresses are available in Settings > About this device.

  • Network settings menu

    The Network settingsmenu has been restructured. Some of the menu items are repositioned, such as alternate TFTP, DHCP.

    For more information about network settings, see Configure the network settings on your phone.

Voicemail configuration

The Voice Mail Enable parameter is added to the phone administration web page. This parameter enables the administrator to turn on or off the voicemail feature on phone lines. By default, this parameter is set to Yes.

For more information about this parameter, see Configure voicemail settings.

Enhancement for group pickup notifications

This enhancement is for the primary line on phones that are registered with Webex Calling.

In addition to the existing BLF notifications, incoming calls to a group also alert group members with the handset LED indicator and ringtone.

For the primary line on the phone, the handset LED flashes red and ringtone plays for incoming calls to other members in the group. The ringtone notification changes with phone statuses, such as idle or on a call.

On the phone administration web page, the new parameter User ExternalID is added to Voice > Phone > XSI Phone Service. The phone gets the User External ID from the Webex Calling server. The populated ID must be matched with that on the server. Otherwise, the notifications don't work for group pickup calls. Administrators can use this information for troubleshooting.
