Proxima, Libra firmware ver. 2.12.xx
rev. 2.12.01
3.4. Calls made by external port
External port is a special type of equipment in Proxima and Libra PBX servers,
that is available after buying an appropriate licence.
A user with external port and mobile phone or any other external number can
become a PBX extension user with full access to the functions and services
according to the assigned privileges.
Extensions set in the PBX server as External port – in order to make these kinds of
calls or to use the server funcions or services – have to make a call on an PBX
external phone number provided by the system administrator. After having
established a connection they’ll hear a server’s continuous dialling tone. Then they
can dial a phone number they want to make a call to or a function/service code
according to the traffic and service class assigned to this extension.
Functions requiring the use of Flash are activated during a call after dialling a
symbol set as Flash by the administrator when configuring the port.
