The phone supports push-to-talk mode with the feature key function Speed Dial, Busy Lamp Field, and Page Group 1
and 2. See the corresponding feature key section on how to enable the PTT mode with each function.
Speed Dial Feature Key
The phone administrator may allocate one or more feature keys on the phone to be used as Speed Dials. To find out
which feature keys are set up as Speed Dials, you can:
-
For a VLK, check the function icon on the respective VLKW on the display
-
For any feature key, press and hold down the key until the respective feature key item is shown on the display.
Then check the function icon of the feature key item.
Note that only the administrator can designate the function for each feature key. The user is not able to change the
function of a feature key as assigned by the admin. The user can however configure the
Number
and
Service
parameter of a speed dial feature key from the phone. The user can press and hold down the key until the
corresponding feature key item is shown on the display and then enter view or change the target number and the
service (a.k.a. line) to use when calling from that speed dial key. To call from a speed dial key, simply press and release
the feature key normally.
To enable the PTT mode on a speed dial, the administrator must include the ptt flag in the Number parameter of the
speed dial. The general syntax is
Number
= {
target-number
}[
;ptt
] where {
target-number
} can be an empty value if
the number is unassigned.
Block Caller ID*
(SIP and OBiTALK only.) Block Caller ID (or Anonymous Call) allows you, when making an outgoing call, to prevent your
name and number information from appearing on the called phone. This is a feature to can be enabled for all calls on
the phone or only for calls on a specific service. For calls on an SP service, the feature may be offered locally by the
phone, or by the soft-switch serving that SP service on the phone. For SP1 – SP6, the parameters that are related to this
service are (where the
