What’s New: Network Call Redirection 5
CMS database 
changes
0
CMS database items are affected by NCR, as follows:
•DEFLECTCALLS: In the vector and VDN tables, the 
DEFLECTCALLS item includes the number of calls redirected using 
NCR through the BSR feature by using the route-to-number ~r or 
queue-to-best commands. Successful NCR attempts are pegged as 
DEFLECTCALLS.
•INTERFLOWCALLS: In the vector and VDN tables, the 
INTERFLOWCALLS item includes successful BSR interflows using 
NCR...

What is Network Call Redirection?0
Overview0Call redirection using NCR is accomplished by using either the public 
network’s NCT or NCD options. For NCD, there are two operations that 
can be used for call redirection: “retain call until alerting/connect” or “clear 
call upon invocation.” NCD is only offered outside of the United States. At 
this time, it is offered in Britain, Germany, Belgium, and France. In the...

What’s New: Network Call Redirection 7
With the “clear call on invocation,” which is the only NCD operation 
currently available, the 
DEFINITY loses control of the call once the call 
has been transferred to the public network for redirection. The 
DEFINITY 
does not retain control of the call until it has been acknowledged by the 
network, so there is no alternative transfer possible if the public switch 
cannot acknowledge and transfer the call to the second location....

Implementation0
Overview0The NCR feature uses either the Network Call Transfer (NCT) or Network 
Call Deflection (NCD) operations provided by the PSTN to redirect an 
incoming ISDN call from a 
DEFINITY Enterprise Communications 
System (ECS) to another PSTN endpoint. In the call center environment, 
NCR is intended for multi-site configurations where ISDN calls are 
interflowed between 
DEFINITY Enterprise Communications Systems...

If NCR is activated using either the route-to-number
 or queue-to-
best
 vector steps, either the NCT or the NCD options may be used to 
redirect an incoming call while the call is still being processed by the 
DEFINITY ECS vector. 
The NCR feature is activated by 
DEFINITY call vectoring if:
•The Best Service Routing feature selection of a “best location” has 
been administered with the...

NCT call success0With NCT, a call transfer is considered to be successful if:
•The public network responds to the FACility message that requested 
the NCT operation with a FACility message to the requesting 
DEFINITY indicating “PSTN success.” The requesting DEFINITY 
should then receive a DISConnect message for both the first and 
second leg of the call after the original call and the second leg are 
joined by the PSTN.
•If the...

NCR and ASAI0NCR is activated by ASAI call processing when the Third-Party 
Merge/Call Transfer operation is requested by a CTI operation. This 
occurs in the following manner:
1. This is typically initiated by the CTI user selecting an icon, menu 
item, or button to transfer an incoming ISDN call to another user on 
the public network. 
Since the incoming ISDN call must be connected to a station user 
before the Third-Party Merge/Call Transfer...

What’s New: Network Call Redirection 13
A successful NCR completion (when the PSTN indicates a successful 
NCT invoke) will terminate vector call processing while the original call is 
connected through the interflowed to call center site by the public 
network. CMS will track this as a successful network call redirection for 
the call.
An 
unsuccessful NCR attempt (NCD invoke failure or NCT secondary call 
failure) results in vector processing going to the next step in the vector...
