External Hot Desking extends hot desking capabilities to an external device, which makes it appear as an extension on the system. When the external hot desk user (EHDU) is logged in to MiVoice Business, a caller only needs to dial the extension number assigned to the user and the system automatically rings the user's cell phone, home phone or other device of choice—including an extension on another private network or PBX.
As a PBX extension, the external device user has access to extension dialing along with select PBX features and enterprise CLID on all calls originated through the system. When a call is extended from the system to an EHDU, the internal state of the user is updated to reflect the busy condition. Since the state of the user is known, an EHDU can be monitored by DSS/BLF keys on other devices. Call diversion features and group features, such as hunt groups, follow the normal treatments for busy, out of service, etc. For example, if an EHDU is a member of hunt group, and is active on a call, the hunting algorithm will skip the busy EHDU and try the next member.
External Hot Desking supports the following additional capabilities:
the ability to remotely change the external device number as well as the login PIN used for authenticating the user and granting access to system resources
access to mid-call features—Hold/Retrieve, Transfer, Conference, Call Swap/Camp-on Retrieval, Handoff, Flash, and Cancel Call—by dialing fixed single-digit codes or system feature access codes while active on a PSTN trunk
access to select system features, such as Call Forward Setup, Paging, Group Presence, through the use of feature access codes.
the option (via Class of Service) to remain permanently logged in
a Call Recognition Service that simplifies or eliminates the need to log in
push-to-answer, which requires the EHDU to press a DTMF key to accept an incoming call (This a Class of Service option used when the trunk terminating on the EHDU device fails to provide answer supervision.)
group membership, including hunt groups, ring groups, personal ring groups, hospitality suites.
a Callback service that recognizes that an External Hot Desk user is calling, hangs up on the user and then calls them back. Mobile phone users can take advantage of this service to save on the charges normally associated with outgoing calls.
the ability to receive message waiting indications
device resiliency
mobile failover operation whereby calls to a desktop device in failover state are automatically rerouted (via CFNA) to a mobile device that is provisioned as an EHDU.
Hot Desk PIN Security for forcing hot desk users to create more secure PINs.
Announcements - a Call Coverage Service that can be assigned to the agent (using the User and Services Configuration form). If configured, announcements are played to the caller when queued to the requested group.
the ability to automatically log out a EHDU. For more information, see Hot Desking - Logout and Scheduling Hot Desk User Logouts.
When a user logs in to a hot desk set, the system associates the user's settings—such as directory number, COS/COR settings, display preferences (such as language), and button programming—with the set.
For EHDUs logged on to private trunks (such as a Suite EHDU), the system uses the CESID associated with the user’s mobile DN. For EHDUs logged on to public trunks (such as a cell phone), the system uses the external party’s public number as the CESID. For EHDUs logged in over public trunks that provide no calling line identify, the EHDU configured external number is used as the CESID.
NOTE: An EHDU external number configured with *, # or P characters cannot be used for the CESID. For EHDUs logged in internally (such as a Minet device), the CESID associated with the originating set is used.
For local notification (SMDR log and attendant console), the system displays the DN and name of the active profile (if available). If a hot desk user is logged in, the user's DN and name are displayed.
IMPORTANT: Emergency calls should not be made from an EHDU device since the call cannot be guaranteed to contain the correct location information. Mitel assumes no legal, financial or personal responsibility for users or persons performing such actions.
