ok.
some more questions.
1) is there a significance of what the numbers are?
my LDNO is 4499 so it is receiving 4 digits.
However, the 4xxx doesnt correspond with any of our DIDs we've ever had at that building.

2) if i want the Telco to start sending me 10 digits, is it just a matter of changing the LDNO to 1234567890?

3) lastly what are the ICI? I have one site with and one without.
ICI 00
ICI 01 R005 LD2
ICI 02 R007
ICI 03 R008
ICI 04 LD1
ICI 05 MWC
ICI 06 CFB
ICI 07 RLL
ICI 08 INT
ICI 09 DL0

Why would you want 10 digits?

your IDC table would be redirecting them if your DID numbers dont match extensions

it will be 10 because we have a unified dialing plan over Voip that spans north america with several different area codes.

Let's say your PBX is based in California NPA 818.

A caller dials your New York office in NPA 212.

Where will that call arrive first? In New York, or in California? I say it is going to land in New York, and that PBX is going to answer. In other words, I am not sure you need 10 digits because you are only accepting calls that translate to your Home NPA 818.

I’m not saying your plan is bad – it sounds intriguing.

This is what the book says on LDN0 as it relates to PRI service:

Listed Directory number 0 must be defined for ISDN PRI DID service.
The length of LDN0 determines the number of trailing digits translated as the dialed DN on PRI DID routes. Up to seven digits can be entered if DNXP option 150 is equipped. Otherwise, up to four digits can be entered.

ICI is Incoming Call Indicator and it only relates Attendant Consoles. It is the place that lights up on the console for that call type. Here are yours explained:

ICI 00 Not defined
ICI 01 R005 LD2 incoming to LDN 2 and over Route 5
ICI 02 R007 incoming over Route 7
ICI 03 R008 incoming over Route 8
ICI 04 LD1 incoming to LDN 1
ICI 05 MWC incoming Message Center
ICI 06 CFB incoming Call Forward Busy
ICI 07 RLL incoming Recall
ICI 08 INT incoming Intecept
ICI 09 DL0 incoming Dial Zero

GHTrout,
Our problem is, we have a centralized enterprise phone system with many sites in different parts of the continent connected to it. Moreever, we have other things within the system like IVRs and queues etc that require some sort of number/extension to identify it.
At 4 digits, we would easily have overlap. At 7 we would eventually overlap. At 10, it just increases the window for us.

Are you able to answer my first 2 questions?
1) is there a significance of what the numbers are?
my LDNO is 4499 so it is receiving 4 digits.
However, the 4xxx doesnt correspond with any of our DIDs we've ever had at that building.

2) if i want the Telco to start sending me 10 digits, is it just a matter of changing the LDNO to 1234567890?


thanks

I sense you are struggling as the "go between" in this. I am not certain you are grasping how the system is going to be routing calls. If your system is as large and complex as you are portraying, you have a wealth of resources with your distributor. They can go right to Avaya and, seeing the future dollar signs, will advise you on what to do. You may be well beyond an Internet Forum. We can offer tips and tricks, but your situation is bigger than a thread on line. Sending 7 or 10 digits would seem to be the least of your worries.

Anyway: The maximum DN length in the PBX is 7 digits. LDN0 cannot be more than 7 digits long.

The LDN0 value you see today does not need to be DID - the PBX does not know what is, or is not DID. It can be a random number, set just to define the length for the PRI.

I would add that it is likely the carrier is going to be the "thing" or "cloud" that performs the routing between cities. You need more horsepower than your PBX alone.

We have Cisco gateways that route calls where they need to be.
So for example, you make a call from California to NewYork. The phone gateway in Cali will match the number to a dialpeer that sends the call to NewYork across the WAN so that the call is made off of a NewYork line and we dont pay longdistance.
There is 1 last nortel we have in 1 building in 1 city. We are planning on decommissioning it soon and getting them on the "new-school" system.
Long story short, the new system would be in place for a bit (while receiving 10 digits from the telco) while the old Nortel is slowly phased out. So the Nortel would need to know how to receive 10 digits for a bit.
So if what you say is true, and the nortel can only receive a max of 7 digits, i will need to have the Cisco gateway strip down the 10 digits before it hits the nortel.

And apologies, dont get me wrong. im not tooting my own horn. my setup is big in the sense that there are enough little offices everywhere that 4 digits isnt enough for us.

Oh, I see... that Nortel is the thorn in your side. I was thinking THAT was the centerpiece of the collection.

I would say your plan is right to have the gateway translate things to the old iron.

I am not positive since it was a few years back, but I recall a Nortel site that Telco swore was getting 10 digits, and it worked. We figured the Nortel was capable of looking at the last 7 digits, or 4 in our case, even though Telco was sending 10, so they said.

It might work without any extra effort.
