Setting Call Back
During network intercom calls, if a calling station encounters DND, RNA, or busy signals at the called station, the
caller can activate a call back operation by dialing the appropriate code or pressing the appropriate button.
The network system then automatically calls back the calling station from the called station whenever the called
station becomes idle (in the case of busy) or makes and ends a call to someone else (in the case of RNA).
Alternately, the user at the calling station can cancel the call back operation by dialing the appropriate code or
pressing the appropriate button anytime before the network system activates the feature.
Setting Message Waiting Lights
Callers from one node to another that encounter DND, RNA, or busy signals at the called station can turn on the
message waiting light at the called station by dialing a message waiting code or by pressing a button designated
for that purpose.
They also can set the message waiting light at another station anytime by pressing their intercom button and
dialing the appropriate code followed by the other station’s extension number.
Recipients of a message waiting action can press the appropriate buttons to call the message depositing station.
Alternately, recipients of message waiting action can clear the message wait action by dialing the appropriate
code or pressing the appropriate button.
Transferring Calls
Station users can transfer intercom calls from one node to another in either a supervised or unsupervised manner.
1. In the supervised manner, the user of a transferring station calls the receiving station and announces the
call to its user before hanging up.
2. In an unsupervised manner, the user merely hangs up after calling the receiving station. While a transfer
is pending, originators can retrieve a transferred call if they wish.
NOTE: Users cannot retrieve intercom calls transferred to another node.
The transfer recall feature does not work with calls transferred to another node.
Transferring Voice Mail Calls
While you can map up to thirty-two different voice mail access buttons (XVM1 through XVM128) on system
stations, the network software reserves mapped button XVM128 as the button for accessing centralized voice mail
on the hub. The remaining index numbers (01 through 127) are available for access buttons that you can use with
local voice mail systems at the nodes.
NOTE: In networked environments, CTI applications that use the transfer to voice mail feature must be used
in conjunction with centralized voice mail.
Using the Impact SCS Large Screen Display Speakerphone
Networking software extends functionally to the Impact model 8412F and 8412S large screen display
speakerphones. Usually, this functionally is generic. This means the large screen display speakerphone makes,
conferences, forwards, and transfer calls to remote extensions, and sets call back and message waiting lights or
accesses the network voice mail in both intra-node and inter-node environments in the manner described in
GCA70–349, Impact SCS Large Screen Reference Manual and amplified upon in the previous paragraphs.
