4. 11. 3 Incoming Calls via a KT Line
All calls can be routed to a KT line if the destination KT is defined in the correspond-
ing call distribution element:
• Calls from the public ISDN network
• Calls from the public analogue network
• Calls from the private network
• Internal calls
If an incoming call reaches a busy KT line, the call is routed to the second KT line. If
the second line is also busy, the call is routed to the third KT line, and so on. If there
are no more KT lines available, busy is signalled. If "CDE if busy" is configured, the
call is routed is via the call distribution element.
Note:
If a call is routed to a KT line to which no line key is connected, the call will
simply idle or be routed to the alternative destination (setting CDE if no
answer).
Transferring from a Key Telephone to another Destination
Each connection on a KT line can be transferred to any internal user. For this simply
press the personal key.
If a key telephone user is already making an internal call and wants to answer a call
on a line key, the response depends on the parameter Internal brokering/line key in
the user settings:
• If the parameter is set on No, the internal user (in order to maintain the connec-
tion) must first be parked before the call can be answered on the line key. In re-
turn the external call can be forwarded directly using the personal key.
• If the parameter is set on Yes, the call can be answered directly on the line key
and the internal user is automatically parked on the personal key. To forward the
external call internally, initiate an enquiry call.
