Every keyset must necessarily have a line key for the primary line. To configure the key of the primary
line, set Primary line to "true". Only one single line can be the primary line. Enabling the primary line
option will disable a possibly previous configured primary line.
If Ring on/off is checked, the line will ring when an incoming call occurs, and a popup will appear on
the display. If the option is not checked, the incoming call will be indicated only by the blinking of the
key's LED. If it is desired that the line ring with a delay, the time interval in seconds can be configured
by Ring delay.
When the user lifts the handset in order to initiate a call, the line to be used is determined by selection
rules. To each line, a priority is assigned by the Selection order parameter. A line with the rank 1 is the
first line to be considered for use. If more than one lines have the same rank, the selection is made
according to the key number. Note that Selection order is a mandatory setting; it is also used in the
Terminating line preference, as well as in other functions.
The Address (Address of Record) parameter gives is the phone number resp. SIP name corresponding
to the entry in the SIP registrar at which the line is to be registered. The phone will register each line
with 'Address@Registrar'.
Remark: For the configuration of line keys, the use of the WPI (Workpoint Interface) [4] is
recommended. For operating the WPI, please refer to the WPI developer's guide. Alternatively, the web
interface or the local menu can be used. Note that the creation of a new line key and the configuration
of some parameters can not be accomplished by the phone's local menu.
Generally, it is advisable to restrict the user's possibilities to modify line keys. This can be achieved
solely by the WPI. For further instructions, see the WPI developer's guide.
The Realm, a protection domain used for authenticated access to the SIP server, works as a name
space. Any combination of user id and password is meaningful only within the realm it is assigned to. If
the Realm is not set by admin, the phone will set the Realm automatically after the first successful
registration. The other parameters necessary for authenticated access are User Identifier and
Password. For all three parameters, there must be corresponding entries on the SIP server.
The Shared type parameter determines whether the line is a shared line, i. e. shared with other
endpoints, or a private line, i .e. available exclusively for this endpoint. A line that is configured as
primary line on one phone can be configured as secondary line on other phones. The MAA
environment is restricted to private lines. Therefore the option must be set to 'private' in this case.
When Allow in Overview is set to "Yes", the line can be visible in the line overview on the phone's
display.
With firmware V2, hot/warm line functionality is available. If a line is configured as hot line, the
number indicated in Hot warm destination is dialled immediately when the user goes off-hook. This
number is configured in the user menu under Configuration > Keyset > Lines > Hot/warm
destination. To create a hot line, Hot warm action must be set to "hot line". If set to "Warm phone", the
specified destination number is dialled after a delay which is defined in Initial digit timer (seconds)
(for details, see Section 3.6.3, "Initial Digit Timer"). During the delay period, the user can dial a number
which will be used instead of the hot/warm line destination. In addition, the user will be provided with
a dial tone during the delay period. With the setting "No action", the line key will not have hot line or
warm line functionality. As the hotline/warmline function is used in special scenarios only it's
recommended not to use this option in MAA environments in general.
