2.2 Forwarding.
Call Forwarding Unconditional (CFU). Incoming calls are immediately forwarded to the number, mentioned at activation of the service. During the activation of the service (checkbox Activity) in the field Destination DN it is necessary to provide a subscriber number, to which all calls will be forwarded. If necessary it is possible to setup Call Forwarding Unconditional, Time Dependent (CFUT), which is located on the tab Forwarding (2).
Call Forwarding Busy (CFB). This service is executed when a terminal of the destination subscriber with activated service CFB can’t accept a new call and responds with busy tone. The call will be forwarded to the number of a terminal, mentioned during the activation of the service.
Call Forwarding No Reply (CFNR). If the subscriber with this activated service will get a call, the timer is started. If the subscriber until expiration time does not respond, it will be forwarded to the specified number, chosen during the activation. For this service additionally the time interval, after which the call is forwarded, can be specified (Not Respond Timer).
Any of these services can be changed to the selective service, for this (e.g. for the service CFU) there exists the parameter Selective CFU (the same for CFB and CFNR) for which the options Authorization and Activity should be chosen. The button More opens the window for management of sampling of lists. Both white and black lists can be created for forwarding. Call from numbers in whitelist will be forwarded, others – not.
For all services of forwarding such parameters are specified:
Destination DN Subaddress;
Call to Forward (set up for Feature Set);
Call Transfer (CT) It allows transferring the active connection to another subscriber. For this it is necessary to hold the current call, dial the number of the subscriber to which you want to transfer the call and after his response to put down the handset (e.g.: during the conversation of subscribers A and B, the subscriber A holds the call, dials the number of the subscriber C and after reply of the subscriber C, the subscriber A puts down the handset, the call is continued between subscribers B and C).
2.3 Identification services:
Calling Line Identification Presentation (CLIP). It is used if the correspondent possibility exists in the terminal of the destination subscriber fot identifying and displaying the number of the call subscriber’s number.
Calling Line Identification Restriction (CLIR). It cancels the possibilities of using of the service CLIP, Override, the activity of the service is specified by the option Activity. Also it’s possible to choose variants of prohibition rights, Authorization:
The absence of the right to use the service, Not Authorized;
The permanent right to use the service, Permanent;
The temporary right to use the service with the default parameter On Demand Allowed;
The temporary right to use the service with the default parameter On Demand Restricted.
Other services of the tab Identification are used less frequently for providing by service providers and will not be considered in this textbook.
