Extension Mobility

Overview 
...........

Extension mobility (EM) profiles (also known as roaming profiles), allow users 
to log onto a phone in another location and the phone automatically adopts
the profile for that user. 

An EM profile is required for users who move between 
locations on a regular basis, or for users in an organization or location, who
have been assigned an extension mobility profile rather than a permanent phone.

VOSS Automate provides three ways to create, manage, and associate extension mobility
profiles:

* Add an EM profile to a subscriber when adding a subscriber in a standard add process (see :ref:`add_subscribers`)
* Add a subscriber using Quick Add Subscriber, and choose an EM profile
* Add a standalone EM profile (see :ref:`standalone-extension-mobility`)

Add an Extension Mobility Profile
.......................................

Standalone extension mobility (EM) profiles allow administrators to create and manage all
EM profiles at the specified organization level. 


* Add or update a subscriber's extension mobility (EM) profile via **Subscriber Management > 
  Subscribers**. From the list view, open a subscriber, and select the **Extension Mobility** tab. 
  See :ref:`add_subscribers`.

* Add or update a standalone EM profile via (default menus) 
  **Subscriber Management > Extension Mobility**. From the list view, choose an EM profile 
  to open its configuration screen, and select the **Extension Mobility** tab. 

When adding or editing EM profiles, you can personalize the profile for each user. 

The table describes common rules for adding an extension mobility (EM) profile: 

================================== ==========================================================================================
Extension Mobility tab             Name must be unique. The name cannot be the same as a device name on Unified CM 
                                   since both are device types. This field is read-only when editing an EM profile.

Lines tab                          * Extension mobility (EM) can be associated to multiple subscribers. If the 
                                     **Show Numbers belonging to this Subscriber** option is chosen as the 
                                     **Inventory Filter**, only the directory numbers associated to the first subscriber 
                                     on the **Subscribers** tab are displayed.
                                   * Line settings can only be changed for the original line, not the clones.
                                   * All line settings changed for a line automatically apply for the clones of that 
                                     line (if any).
    
Speed Dials tab                     Allows you to manage the speed dial numbers associated with the EM profile. 

Services tab                        Extension mobility (EM) profiles can be subscribed, unsubscribed, and re-subscribed 
                                    to IP Phone Services such as Intercom Calls, Login/Logout, or SingleWire. Once you 
                                    choose the IP phone service, the system retrieves the URL and a custom parameter 
                                    (if any, for example, Ext1 and Ext2) from ``device/cucm/IpPhoneService`` and 
                                    populates the **URL** field. 

Subscribers tab                     Allows you to associate the EM profile to one or more subscribers. You can 
                                    also disassociate an EM profile from a subscriber by clearing the name from the 
                                    **Username** drop-down, and saving the change. The **Subscriber** link on an 
                                    existing EM profile links to the associated subscriber's **Extension Mobility** 
                                    form (default menu **Subscriber Management > Subscribers**).
