The user can also make a choice on a menu by pressing the corresponding numeric value appears to the
left of the menu item. After entering one or more digits and if the number of items in the menu is such that
another additional digit may still result in a valid choice, the SPA-841 will wait for the next digit for 2
seconds before processing the selection. Note that the SPA-841 will ignore any leading 0 digit entries. If
the user press a digit sequence that is outside the range, the SPA-841 will simply position the highlight to
the first or the last item on the menu. Depending on the menu, selecting a menu item by pressing the digit
keys may automatically perform the default action on the item, or simply repositioning the highlight on that
item (i.e. no default action). For example, on the Speed Dial or Directory menu, the default action is to
edit the selected item as if the item is selected by pressing SK(edit). On the other hand, there is no
default action on the Redial List or Missed Calls menu.
When a menu is shown on the screen, the status line (between 2 soft key labels) will show the title of the
menu. If the menu is invoke as a submenu under the
i
button, the
i
symbol will be prepended to the
menu title. This indicates that the user can exit all the way from the setup menu by pressing the
i
button
again.
A menu item may have contents that are wider than the LCD can show. When the user highlight the item,
the SPA-841 will automatically scroll the contents horizontally from right to left so that the user can view
the entire contents.
Definitions for the Four Call Appearances
Some definitions:
•
Station: A SPA-841 phone (or similar device) with one or more Extensions and Call appearances
provisioned
•
Ext: An extension in the SPA-841 is a VoIP account in a voice service provider (VSP)’s network
or an IP-PBX system. An extension can be uniquely identified with a User ID (like a phone
number) that is unique within the VSP. Up to 4 extensions can be configured in the SPA-841,
which we will refer to as Ext 1, Ext 2, Ext 3, and Ext 4 (or simply E1, E2, E3, and E4 respectively).
Note that the same extension can be configured on more than one station. These extensions are
called
Shared Extensions
. Extension 1 is referred to as the Primary Extension. Some features
can only be activated on the Primary Extension such as Call Forwarding and VMWI.
•
Call Appearance: Physically a call appearance corresponds to a Line Key on a station. There are
4 Line Keys in SPA-841, which we refer to as Line Keys 1, 2, 3, and 4 (or, simply, L1, L2, L3, and
L4 respectively). Functionally a call appearance is an instance of an extension. We call it a
Share
Call Appearance
if the associated extension is shared. Multiple instances of the same extension
can be configured on SPA-841. In fact all four call appearances can be instances of the same
extension. Note that call appearances (on the same station) which are instances of the same
extension are shared call appearances if and only if the extension is. Any of the 4 Line Keys can
be disabled in the configuration. Each call appearance supports one call at a time.
•
VoIP Interface (VI): An Extension and its associated control parameters configured on a particular
station. The SPA-841 includes a rich set of configuration parameters to control the operation
when calling via the account. When configuring an extension on the SPA-841, we are configuring
the core account information as well as the set of VI control parameters. While the account
information is usually the same for a shared extension on different stations, the rest of the VI
parameters can be very different (such as the dial plan or the preferred codec to use when
making a call on this extension could be different for 2 different stations sharing the extension).
•
Call Appearance State (CAST): The state of a call appearance which can be one of the following:
o
Disabled: The Line Key is disabled
o
Idle (Ready): The Call Appearance is ready for use
