While I was searching for your answer , I came accross with this ...This might help you
DNIS is the number sent to you by your telco,,, usually the last 4 digits of the number,
VDN is Vector Directory Number, it is a pointer to a vector for vector processing.
If your DNIS matches the VDN then it will just flow to the vector. If it is different, then you would need to manipulate it with incoming-call-handling-treatment.
Alot of the telcos will let you request a DNIS for the 800#,,
so lets say you had a VDN for the test call,, 5555, and and 800# of 800-123-4567, you could either ask the telco to send 5555 for the DNIS, or you would need to use incoming-call-handling to convert 4567 to 5555.
If you had 800-123-4567, and your vdn was 4567, then you probably would not need to do anything
