6900 Handset Engineering Guidelines

This section of the engineering guidelines provides information on the architecture and implementation of the 6900 Handsets on the MiVoice Office 250.

Overview

The 6900 handset is Mitel's new premium range of telephones. Currently there are three models of handset available; 6920, 6930 & 6940. From release 5.1, the MiVoice Office Application Suite supports the 6900 handsets and acts a configuration server to allow many of the MiVoice Office 250's features to be used on the 6900's SIP telephones.

From 5.2.20 Support was added for the 6970 IP Conference Phone

SIP Implementation

To connect to the MiVoice Office 250, 6900 handsets operate as a SIP extension. All call control functionality is provided through the SIP connection directly to the telephone system (or via a MiVoice Border Gateway).

Each 6900 handset requires a Cat-F license on the telephone system.

Out of the box, all 6900 handsets come with MiNET firmware for a MiVoice Business. SIP firmware must be loaded onto the handsets before they will connect to a MiVoice Office 250.

Licensing

In addition to the Cat-F licensing on the telephone system, there are two levels of license on the MiVoice Office Application Suite that are used to control 6900 handsets:

Mitel 6900 Handsets (Basic), provides access to core functionality (Firmware, Keymaps, Configuration, Paging etc)
Mitel 6900 Handsets (Advanced), provides access to advanced functionality (Currently this includes the ability to Change Caller ID and Recording Pause/Resume toolbar buttons).

Without a license, the 6900 handset can still be connected to the telephone system but would need to be manually configured and would only support the basic SIP features.

Licensing may change at any time. Please refer to the latest product bulletins for updates on how 6900 handsets are licensed.

Implementing 6900 Handsets on MiVoice Office 250

The following sections cover various aspects of 6900 handset implementation on the MiVoice Office 250.

Connectivity, provides information on the architecture of how 6900 handsets, the MiVoice Office 250 and MiVoice Office Application Suite work together.
Rollout, provides information on how to install 6900 series handsets including MiVoice Office 250 configuration, firmware updates and MiVoice Office Application Suite configuration.
SIP Hot Desking, provides information on how SIP hot desking works and how it is configured.
Teleworker/Remote worker, provides information on how 6900 handsets can be implemented in Teleworker/Remote worker scenarios.
Multi-Node, provides information on how 6900 handsets can be implemented in multi-node environments.

69xx Power Requirements

A 69xx working with a DECT headset is still a standard class 3 POE device. As soon as a single PKM is added it requires additional power and becomes a class 4 POE device (See Notes below).

Device Config	POE Class
6940, 6970	3
6940 With DECT Headset	3
6940 With 1 M695 PKM	4 (See Notes 3 & 6)
6940 With 2 M695 PKMs	4 (See Note 3)
6940 With 3 M695 PKMs	4 (See Note 3)
6940 With 3 M695 PKMs + DECT Headset	4 (See Note 3)

An external DC power supply is available for the phones: 50006924 - 6800/6900 AC Adapter Universal.

Note 3: Attention - Devices that require more than 12.95 watts are designated as IEEE 802.3at Class 4 devices. To operate correctly, all IEEE 802.3at Class 4 devices must be connected to a L2 PoE switch that is IEEE 802.3at compliant. Some IEEE 802.3at L2 PoE switches require connected devices to send power allocation requests in excess of 12.95 W (Class 4 devices) using LLDP-MED. Therefore, Administrators must ensure that LLDP-MED is enabled on the L2 switch.

Alternatively, IEEE 802.3at Class 4 devices may be powered with an in-line IEEE 802.3at power injector, or if supported, an AC to DC adapter.

Note 6: Upon initial power up, these sets (with associated accessories) will advertise their power Class via IEEE 802.3at. Once these sets have completed power up, they will advertise modified power requirements via LLDP-MED that are less than what was reported by the IEEE 802.3at Class advertisements. However, the L2 switch must have LLDP-MED enabled to take advantage of the lower power advertisement.
