6900 Handset SIP Hot Desking

SIP Hot Desking is a feature that has been designed specifically for 6900 handsets. Any '69xx/Phone Manager SIP Phone' extension on the telephone system can be configured on the MCS as a SIP Hot Desk Phone. Once this has been done, it can be used to log onto any 6900 handset connected to the MCS server that has been enabled to accept hot desk logons.

SIP hot desking is different from both agent hot desking and MiVoice Office 250 hot desking. The different types of hot desking cannot be used together.

SIP Hot Desk Features

When logging into a 6900 handset with a SIP hot desk login, the handset will be reconfigured so that it becomes the hot desk extension. The following list shows what configuration gets updated on the handset:

SIP credentials (Extension No, Username etc)
Keymap
Configuration Options

When a SIP hot desk logs in to a handset, the handset will cease to be its base SIP extension and will become the SIP hot desk extension. If the SIP hot desk that has logged in resides on a different node than the handsets fixed extension, the handset will un register as a SIP device on one node and will re-register on the new node where the handset resides.

When the SIP hot desk logs out, the handset will revert back to its fixed extension.

SIP Hot Desk phones can be configured on the MCS for all features that a fixed 6900 handset can:

Configuration Profiles
Keymaps
Alarm Notification
Page Zones

All of the above features will be applied when a SIP hot desk phone logs on.

If a SIP hot desk phone has not been assigned a Keymap Profile or Configuration Profile directly, the keymap and configuration profiles for the base extension will be used.

Adding a SIP Hot Desk Extension

A SIP extension to use for Hot Desking is no different in PBX configuration from a SIP Extension used as a base handset extension. Any SIP extension not assigned to a base extension is available for use as a SIP Hot Desk Extension

On the MCS server, Configuration -> Features -> 6900 Handsets

Enable Base extensions for Hot Desking

In the Phones section edit all the base extensions you will want to be able to SIP Hot Desk into and Tick the 'Enable Hot Desking check box'

Enable an SIP Extension to be a Hot Desking device

In the SIP Hot Desking section, press the 'Add' button. In the form that appears, enter the number of the SIP device on the telephone system to configure as a hot desk phone (the device picker will filter out any SIP device which are already have a fixed mapping to a handset).

Once a hot desk phone has been created, it can be used to logon to any handset that has been enabled for accepting hot desk logons.

It is important to set authentication against each SIP extension and ensure the password is complex. For example, Mitel*Server1!. If connecting externally through and MBG, a complex password is a requirement.

If a user is using a 6900 handset and a softphone (on either or both of Phone Manager Desktop & Phone Manager Mobile) it is important to set them up with separate SIP Endpoints on the phone system.
