DNIS and ANI

[guycable2]

Hi

I am working with our LD provider (AT&T) to provision our LD T1s to ISDN PRI. We have several 800 numbers that are provisioned on these T1s and AT&T says we can block ANI by 800 number to avoid being charged the per call fee on all of our 800 numbers. However the way they say we need to block it is with our PBX.

I have done lots of research in the NTPs and can't seem to find how to do this. Has anyone ever had to do something like this? Is it even possible?

I should add we use AT&T on-net service to dial DIDs between sites so blocking caller id isn't an option. This is in fact the reason for our upgrade.

Block ANI by 800 number"

The call is coming to you though - what's to block?

I'm not sure what that could mean.

I would be blocking the ANI of the person that called the 800 number.

Info from their quote.

• If ANI is ordered and (not blocked by the pbx) the additional charge is xxx per call placed on our toll free numbers.

• PBX configuration to allow or to block ANI is done by each Toll Free Number (The PBX would control which TF #’s you would be billed ANI for.)

Well, one thing I can add is this:

Let's say you use AT&Ts SDN (or whatever the latest term is) and you have offices very close to each other.

AT&T will certainly suggest that you use their facilities to call between local offices. But if the billing plan when you are on their SDN network is a higher cost per minute than if you just called the nearby office "local" then you are better off not using SDN in that call example.

Just a thought

Oh that's easy. AT&T is wrong in my opinion. Your PBX cannot force AT&T's switch to anything. If you say you want to see Caller ID, then AT&T turns it on. If you say "no caller ID", then you won't see it. Your PBX cannot tell AT&T not to do something on an incoming call.

As for "ANI" - it's always there. Otherwise, AT&T would not be able to prove anyone ever called you. So, tell them "no ANI" and when the first bill arrives without any calling party info, tell them you have no intention of paying for calls they can't identify actually called you.

Well, you know what I mean. It sounds like the wording they sent you is a little off. New sales engineer maybe.

GHTROUT These locations span three states and the "On-Net" service definitely saves us a significant amount of money. When the sites are close enough for local dialing they are usually on our Network of PBXs sharing a dial plan and an LD T1. Thanks for the suggestion.

Good I'm not the only one that has never heard this. I'm going back to them and asking if they have an example customer using this. Sounded fishy to me from the get go.

Actually the AT&T rep has been there for quite a while and usually seems to know what she is talking about.

I agree the ANI is always there we are just starting to research if we want to display it in our Call Centers, use it for routing, etc.....

It's always on the call detail from them.
