DNIS confusion 2

[vee2058]

There is one 1-800 number that our company utilizes. I know the DNIS number that is sent back to us by our telephone provider. I put that number into the OUTSIDE CALLS trunk and have the calls transfer to a local extension. I can make all other incoming calls work well except the 1-800 number.

Thinking maybe the first DNIS number may be faulty, we had our provider send with a new DNIS number. Same results. Instead of the calls going to the programmed extension they default to our console (internal operator).

I don't understand what I'm missing here!

DNIS refers to a string of digits being sent in the call setup message to identify to 800 number coming in on a dedicated LD trunk group. It sounds like you're confusing DNIS with an 800# terminating via switched service to a local POTS, CO, or DID line. Usually DNIS is a 4 digit number matching the extension number you've programmed in your PBX to accept the call. If you've told your provider to send 555-555-1234 as the DNIS, the call will terminate to your attendent unless you have an extension 5555551234 defined (which isn't even possible pre R11). -CL

Actually in the 555-555-1234 example above, usually the first six numbers is a RTN (routing transit number) which refers to your trunk group, and the last four numbers is your DNIS.

The RTN is not passed to the customer. If a customer asks for a 10 digit DNIS they'll get a 10 digit DNIS. DNIS is independent of the RTN. -CL

Well what I got back from provider is that the 1-800 number is sent through the DMS Switch and comes back as another 4 digit number which I was told is a DNIS number. THIS number is then sent to our PBX.

Maybe it be best if they just kept with the last 4 of the origional 1-800 number? But on the other hand...digits are digits? NO?

We had a similar problem when we went from switched to dedicated toll free. The phone company was sending the full phone number instead of just the extension. The extension doesn't have to be a DID, it just has to exist on the switch. We have it pointing to a VDN which then routes to our call center via vectoring.

I hope this helped.
