Call Completion
Call Completion is the same service as Call Back, except that it is conducted within a
networking connection environment, and is used at H.450 protocol standard specification.
There are two kinds of call completion as follows:
Completion of Calls to Busy Subscribers (CCBS)
- After calling a user in another system
using basic call and encountering a busy tone. A station user can be notified when the busy
destination of another system becomes idle. If the user wants to make a call to the destination
on that notification, the call can be reinitiated to the destination of another system again.
Completion of Calls on No Reply (CCNR)
- After calling a user in another system using basic
call and encountering no reply. The caller can be notified when the destination becomes an idle
status after some actions. If the caller wants to make a call to the destination, the call can be
reinitiated to the destination again.
Operation
To activate CCBS, use the following procedure:
1.
Dial a Station on another networking System.
2.
If the busy tone is provided, press the [CALLBK] button; a confirmation tone will sound,
and the call will be disconnected.
3.
When busy Called Station returns to Idle, the Caller will receive a call-back ring.
4.
When the Caller answers the call-back ring, a new call will be initiated to the Calling
Station.
Conditions
•
A new Call Back request left at a Station will cancel any previous callback messages.
•
A voice message cannot be left even though the VMIB is installed in a local system.
