VDN Return Destination Considerations

If the host security is not passed, the host will route the call to an appropriate alternate destination (e.g., announcement with security violation message) and log the invalid call attempt.

If the host is not available, the call will be disconnected after an announcement (vector step 7 above).

After the called destination disconnects from the call, the caller can remain on the line to be connected to the Return Destination. A sample Return Destination vector is as follows:

1.collect 16 digits after announcement 1002 ("Please enter the telephone number of your destination followed by # sign")

2.adjunct routing link 1221

3.wait-time 6 seconds hearing silence

4.disconnect after announcement 1003 ("We are sorry, but we are experiencing technical difficulties at this time, please try again later")

Figure C-2. Sample Return Destination Vector with Disconnect

The caller, once connected to the Return Destination, can enter a second destination/phone number to connect to. The host performs the same validation on the destination number as in the first destination and routes the call as appropriate (destination entered by caller or alternate destination). Note that the host can also provide reports on all the destinations and times reached by each remote user.

In the Return Destination vector, it is recommended that the first vector command give the caller the opportunity to disconnect from the call rather than immediately routing the call to some destination. If the call was immediately routed and then the caller decided to hang-up, the destination that the call was routed to would ring, alerting the called party, but then no one would be on the line at the other end (this could be confusing to customers, and could be misinterpreted as a problem with the feature). Vector commands such as "wait", "collect after announcement", and "announcement" can provide the caller with the opportunity to disconnect before the call is routed. As an example, an "announcement" command with the recording "Please hang-up to end your call, or remain on the line if you wish to place another call" instructs the caller to disconnect, before the call is routed.
