Basic Call Vectoring

Issue  4 September 1995

The following vectors illustrate how interflow is used:

In the first vector, a branch is made to Step 8 from Step 2 if the condition in the 
latter step (

oldest call-wait in split 1 > 120 seconds

) is true.  If the condition is 

false, a branch is made to Step 9 from Step 3 if the condition in the latter step 
(

calls-queued in split 1 > 10

) is true. If that condition is also false, the call is 

queued (Step 4), and a wait-announcement loop becomes effective (Steps 5 
through 7).

If a successful branch to Step 8 is made from Step 2, the 

route-to number

 

command is executed.  The destination number (2020) in this particular 
command is a VDN.  Accordingly, vector processing terminates in the first vector 
and begins at the first step of the second vector, to which the VDN points.

Once processing control is passed to the second vector, the caller is provided 
with the appropriate announcement (Step l).  Thereafter, upon execution of the 

messaging split

 command in Step 2, the system attempts to either queue the call 

to the message service split or else terminate the call to a message service agent 
or to an AUDIX voice port.  If one of these attempts succeeds, the caller may 
leave a message. If none of the attempts succeed, the command fails, and 
vector processing continues at the next vector command (usually an 
announcement explaining that the necessary connection could not be made).

Vector initiated Service Observing is available with G3V4 and later releases. For
