Advanced Operational Features

You can configure the boot sequence recovery mode parameters using the configuration files
only.
CONFIGURING BOOT SEQUENCE RECOVERY MODE
For the specific parameters you can set in the configuration files for boot sequence recovery
mode, see Appendix A, the section,
“Boot Sequence Recovery Mode Settings” on page A-287.
AUTO-DISCOVERY USING MDNS
The IP phones can perform an auto-discovery of all servers on a network using mDNS. When
the IP phone discovers a TFTP server, it is automatically configured by that TFTP server.
An unconfigured phone (phone right out of the box) added to a network, attempts to
auto-discover a configuration server on the network without any end-user intervention. When
it receives DHCP option 66 (TFTP server), it automatically gets configured by the TFTP server.
An already configured phone (either previously configured by auto-discovery or manually
configured) added to a network, uses its predefined configuration to boot up.
AS-FEATURE-EVENT SUBSCRIPTION
The IP phones support server-side Do Not Disturb (DND), Call Forward (CFWD), and Automatic
Call Distribution (ACD) feature events. This feature is called “as-feature-event” and works with
the DND, CFWD, and ACD keys.
This feature is configurable using the configuration files or the Mitel Web UI.
HOW IT WORKS ON THE PHONE UI
When you enable the “as-feature-event” on the phone, AND you activate a DND, CFWD, and/or
ACD key, pressing the key performs as follows:
Note:
After the phone has been successfully recovered through the web recovery mode,
the phone will fully download and upgrade to the firmware defined in the configuration
files (upon reboot) or pushed through the Web UI even if the defined/pushed firmware’s
version is identical to the version already loaded on the phone.
CONFIGURATION FILES
Notes:
1.
Configuration parameters received via DHCP do not constitute configuration
information, with the exception of a TFTP server. Therefore, you can plug a phone
into a DHCP environment, still use the auto-discovery process, and still allow the
use of the TFTP server parameter to set the configuration server.
2.
DHCP option 66 (TFTP server details) overrides the mDNS phase of the
auto-discovery. Therefore, the DHCP option takes priority and the remaining process
of auto-discovery continues.
3.
As the phone performs auto-discovery, all servers in the network (including the TFTP
server), display in the phone window. However, only the server configured for TFTP
automatically configures the phone.
