3.2. External calls
External calls – calls between extension users (server users) and outside parties.
Outgoing calls may be made by authorised users only (privileges of each server
user are granted by the server installer or by the service technician in the computer
program).
The basic method of accessing trunk lines is to press 0. Using the computer
program, the installer determines the trunk lines which will be available to a given
user after pressing 0. In addition, the installer may make the following trunk lines
available: *81, *82, *83, *84 and *80a*b*c#, where: a – unit number, b – slot
number, c – port number on the server card, while * is a function access symbol.
If you want to make an external call:
Pick up the phone.
You will hear a dialling tone.
Dial
You will hear:
local exchange (LE) dialling tone
engaged tone if the trunk lines connected to the server are engaged
“unavailable” tone if your phone is not privileged to make outgoing calls
or if its trunk line is blocked with an individual code.
Dial an external number.
You will hear a ring-back tone from the local exchange. The tone type
depends on the status of the outside party – idle, engaged or unavailable.
If an external number is engaged, a call to this external number may be booked
(Booking of a call to an external number – functions: *92, *94, *95).
It is not possible to programme direct access to a trunk line using the telephone
(i.e. without dialling “0”), but it is possible to do so from the computer program
level – the so-called Hotline.
Hotline is not available from VoIP phones.
