Call Menu
The call menu allows the user to place a call by either inputting the resident ID or looking the resident
up in an alphabetical list. The calls menu also allows broadcast speech (optional). The Quickdial
function is not supported.

Placing a call using resident ID
Press the 'Resident ID' key on the Call Menu. Enter the Resident ID, with leading zeros for IDs less than
100 (e.g. enter 20 as 020). Pressing the 'Clear' button at any point clears any input numbers and
pressing 'Exit' returns to the Call Menu. Once a 3-digit number has been entered the SCP will check
that the ID exists in the database. If the ID does exist the 'Call' button will illuminate and pressing this
will start a call attempt.
Placing a call using resident lookup
Press the 'Resident Lookup' key on the Calls Menu. A list of residents in the system will be displayed.
This list can be navigated by pressing the '<' and '>' keys to scroll up and down respectively. For faster
searching through large lists the alphanumeric keys can be used to move through the list
alphabetically in much the same way as a telephone or mobile keypad. For example, to jump to
residents beginning with the letter 'H', press the 'GHI' key (key '4') twice. To select a resident, press
the illuminated key by their name. The SCP will display ‘please wait connecting…’. It will then allow
the user to select ‘call’ to call the resident, ‘skip’ to move to the next resident ID in the list or ‘Exit’ to
return to the Call Menu Screen.
Handling a Call
In processing a call, the SCP will attempt to establish a connection between the residents speech
module and the SCP phone or telephone line 3 (telephone line 3 should be on-hook at this point
Once connected, the caller has the option to terminate the call by hanging up or pressing the 'Clear'
button and can change the mode of connection being used (see Fig. A.6).
The connection will start in the default mode for the resident’s speech module, and will allow
appropriate changes from there. The sequence of possible modes is HVS -> VOX -> PTT. In HVS
(Hands-free Voice Switched) mode, both participants in the conversation appear to talk
simultaneously. In VOX (Voice Operated switching) mode, the system will automatically detect who is
speaking and allow one-way communication on this basis. In PTT (Push-To-Talk) mode, the bottom
right hand key will alternate between 'Talk' and 'Listen'. Press 'Talk' to enter talk mode, and 'Listen' to
enter listen mode.
