VDN Calls
Issue 4 September 1995
6-13
As with other Advanced Vector Routing conditionals, the VDN for a
goto
step can
be specified in three ways: a VDN number, the value “latest,” or the value
“active.”
The following section describes which calls are included in the VDN Calls counts
and which are not.
Counted Calls
The VDN call count includes:
■ Incoming trunk calls that route directly to the VDN.
■ Incoming trunk night service calls where the VDN is the night service
destination.
■ Calls that cover or forward to the VDN if it is the first VDN routed to and the
call is an incoming trunk call.
■ Already counted calls that are conferenced with counted or not counted
calls from the same VDN.
The VDN call count does not include:
■ Internal calls to the VDN.
■ Calls that are transferred to the VDN.
■ Calls redirected to their VDN return destination.
■ Conferenced calls previously counted on different VDNs.
Example
The following example shows how the
counted-calls
conditional can be used to
route calls.
Figure 6-7. VDN Calls Routing
If more than 100 calls are active in VDN 1234, the caller will hear busy tone and
vector processing is terminated. If 100 or fewer calls are active, the call queues
to split 60.
1. goto step 3 if counted-calls to vdn 1234 <= 100
2. busy
3. queue-to main split 60 pri l
4. wait-time 20 seconds hearing ringback
5. announcement 27000
6. wait-time 60 seconds hearing music
7. goto step 5 unconditionally
