How to terminate a DID via ISDN-PRI 1

[Ding07]

We're in a process of converting some of our "copper" terminated DID numbers (e.g. 814-123-4567) to ISDN-PRI T1 with the service called ISDN-PRI LOCAL provided by our LEC.

We have Avaya S8700 ACM1.3. Based on what I have learned so far, LEC (Verizon in our area) will send (at least) the last 4-digit of a 10-digit DID number, then I will have to create a 4-digit VDN 4567 with a call vector to terminate 814-123-4567 to a needed location (e.g. an internal extension). I'd appreciate it if you would provide any advices on how to implement DID ternimation via ISDN-PRI T1 trunk group. Since there is no incoming destination for an ISDN trunk group, I assume that the only way to properly terminate a DID call is to use a VDN with a call vector. Is there any document to do this? I've not found any in my Avaya S8700 set as of yet. Thanks in advance!

The 4 digits will be sent by the provider (could be more or less depending on how it was ordered)

In any switch, the 4 digits should be a valid extension.
You can assign a station, hunt-group, vdn, terminating extension group, etc.... Or if not defined, you could use UDP or ENP to route the call from the terminating switch to another switch over tie lines. You could route extensions that are not defined in the switch to intercept (attd or announcement) or to an attendant queue.

There is not a document that describes this as there are way too many options and Definity feature programming is very flexible.

try this command:
change inc-call-handling-trmt trunk-group x , where x represents your PRI trunk group number..

AvayaTier3,

Thank you very much for your advice! Your response confirmed what I got from some discussions with my "official" support. This is good news.
Here is the "bad news" to me, some 4-digit numbers are already used in our dial plan and most of them may not be easy to change. For instance, the last foru digits of 814-123-4567 "4567" is already used by a data-extension assigned to one our C-LAN card, and some other are already assigned some live DNIS numbers associated with live numbers. Do I have to ask for some new DID number with the last 4 digit numbers accepted by our Dial Plan? Thanks again!

kank,

Thank you for your response! What is "inc-call-handing-trmt"? I can't find this command in my system (Avaya S8700 ACM1.3).

Thanks!

 

[AvayaTier3]

you can redirect this to a different number on the trunk-group form

when the provider sends you digits that don't match your dialplan

--------------------------------------------------------------------------------

this can come in handy. provider is sending 6842 and let's say in your switch that 6 length of 3 is used
for TAC for all trunk-groups. This will receive 6842 and send the call to 7482.

AvayaTeir3,

I am excited! Please corret me if I am wrong with the following.

For instance, to replace "3618" (the 4-digit Verizon is sending) with "7401" (my new terminating extension) enter command:
1. Enter command "change trunk-group 23"
2. Goto page 3, enter the following:

Service/Feature: public-ntwrk
Called Len: 4
Called Number: 3618
Del: 4
Insert: 7401
Per Call CPN/BN:
Night Serv:


I hope this is it!

Thanks!

Yes, that is one place you can do it.

Another is as suggested in post above by "kank"

change inc-call-handling-trmt trunk-group xx

AvayaTier3,

Thanks very much for your quick response!

1. I can't find "inc-call-handling-trmt" under "change", "display" or "change" command. Is this a new item under newer version? (we have ACM1.3 or MultiVantage 1.3) or something we have to turn on via system-parameters customer-options?

2. I think I'm OK for right now with the trunk-group based incoming call handling treatment pages you recommended. The only issue may be that there are 18 (rows) x 3 (pages) = 54 entries in total I can use to replace the incoming digits.

 

[AvayaTier3]

change inc-call-handling-trmt trunk-group xx

This command is not available until cm3 version and higher

This is the same as what you can do for R011 using the change trunk-group command.

As always, I thank you all for your valuable assistance!

One of our PRIs are down and the phone carrier is redirecting all of our DIDs(about 300) to our other PRI. How do I get those calls to pass directly to their stations? If I use call treatment, it seems that I can only handle each DID one line at a time....

Where do I go to tell the trunk group#10 to forward these calls to the DID station number that was dialed? Thanks
Val

 

[AvayaTier3]

look at the incoming call handling treatment for the trunk-group that is down. Duplicate this on trunk-group 10.

It will look something like this. You need to know how many digits and what digits your provider is sending. But if the other trunk-group worked, it should be easy to program the new trunk-group the same way for a temporary resolution.

Thanks for responding....I looked at incoming call treatment and there are 3 entries tied to 3 specific DIDs. When I asked the carrier to redirect my calls to the PRI, they asked for a lead DID number. So they are pointing everything to this 1 Lead DID and on incoming call treatment, it seems like I can only make that lead DID terminate to a specific internal number versus having it know how to handle all of the 300 DIDs. Do I need to tell my carrier something different?

 

[AvayaTier3]

I would tell them to direct all DID blocks of numbers to the new group the very same way they pointed at the old group.

Sounds like they just want to call forward your main number.
I would not agree with that.

I will check into that. Since we are waiting for the other PRI to be repaired, I wonder if this is the only option that they will give us under short notice. Thanks

 

[AvayaTier3]

This is not an unusual request. They should be able to accommodate you with no problem. This stuff happens all the time. Don't take no for an answer.

take names, ask for managers if you must. You are out of service.
