Callers can dial a general number, for example, 615-3111. The caller is provided service in part using Call Prompting. The following figure depicts how a call to VDN 3111 is processed using Call Vectoring.
After the number is dialed, the call is directed to VDN 3111, which points to vector 1. Note that there are no skill preferences assigned to VDN 3111, which is the only VDN that is administered to point to vector 1. Therefore, VDN 3111 is used for calls from all states.
The collect digits command in step 2 of the previous vector first requests the caller to enter the appropriate 2-digit state code and then collects the digits. If the caller enters the correct code for Texas, which is 05, the converse-on skill command in step 3 delivers the call to the converse skill if there is a queue for the skill and the queue is not full, or if a VRU port is available.
When the VRU port responds, the step outpulses the state code 05 to the VRU using the passing digits parameter that is included in the command. Once the VRU receives this state code, the VRU in turn outpulses the Texas VDN (3222) to Communication Manager. Thereafter, the collect digits command in step 4 collects the digits that comprise this VDN. Finally, the route-to digits command in step 5 routes the call to Texas VDN 3222, which points to vector 2.
