DialPlan Question

[prflash]

Have an issue and I believe I know the answer but want to ask the community. I am trying to use 8 as the AAR access code but the system tells me to check the dialplan. In the dialplan 8 is administered as a FAC lenght is 1 digit. Then it has 81,82,83 etc as 4 digits in lenght and as an ext. Am I going to be allowwed to use 8 for AAR access if the other strings that start with 8 are already extensions?

If I can use the 8 then what am I doing wrong.

I inherited this Avaya 8730 CM 5.2. The Home office now wants to use Cisco and use AAR to connect via the WAN to all other offices. I was able to use 8901 as a FAC for AAR but they do not want the users to dial an extra 4 digits.

Why do you need an AAR access code the first place? Just put what extensions you want to route in your dial plan and send them to AAR.

If you must do this, then remove the 4 digits that start with 8. Ehen you dial the AAR access code you get dial tone. With that said you would never be able to dial 8XXX.

do you get an error when trying to administer 8 as AAR feature-access code?

With your dialplan as is and using mixed numbering (stations, tac, fac, dac of different lengths beginning with the same first digit)

shorter length dac, fac, tac, ext have a built-in 10 second timeoout. That timeout can be cancelled by hitting the "#" key. The 10 second wait is to see if the user is going to dial another digit.

On specific CM loads if you try to mix first digit with some 2, 3, 4, or longer digit lengths that cause conflicts, the dialplan change will return an error that will explain what you can and cannot mix.

5 digit station (longest length beginning with 8)
81234

tac (dial 84# or 84 and wait 10 seconds)
84

fac (dial 8# or 8 and wait for 10 seconds)
8

PhoneGuy55 your answer is confusing. Do you have another way that I can have users in this facility access a routing table that will send certain digits that co-incide with pre-determined locations and route those calls to that location. Example: Site A wants to talk to Site B. Site a dials 8 901XXXX to reach Site B. 8 is the AAR access code and 901 is Site B code followed by 4 digit extension at Site B. The Avaya would send those digits minus the 8 to a Cisco that will route the call to the correct location. Basic DCS routing.

Tier3,

So basically I cannot use 8 as an AAR code unless I explain to the pwers that be they will have to wait 10 secs after hitting the 8 or 8# before they can begin dialing the other sites. Just great. That isnt going to work for them. Any other good alternatives to this problem. Ive never had this issue before becuase almost all Avaya PBX's I have worked on came with 9 as the ARS code and 8 as the AAR code. Thought this was standard.

The way I see it, you have a couple of options

1. change your dialplan and get rid of the conflicts with the first digit 8

2. use uniform dialplan programming. UDP uses AAR route patterns without dialing the AAR access code.

what he said ^^^^. There is no reason to dial 8 + tac + XXXX. Just dial XXXX and let the PBX figure out where to route it.

Uniform Dial Plan
UDP range 7700 - 7799

You must use UDP to dial only 4 digits. If any stations local to this R11 csi
are 77xx, you won't be able to get to the IP PBX with these 4 digits.
They can only exist in one switch.

If you do not use UDP, you can TAC dial or use the AAR access code.

Let's make the RNX for the IP PBX switch 999
RNX codes are assigned to identify different switches.
When you see them used in list aar analysis you will know what they go to.

example:

Node 1 991
Node 2 992
Node 3 993
.... . ...
.... . ...
.... . ...
Node 9 999

UDP Extension Search Order: udp-table-first

If any stations local to this R11 csi are 77xx, you won't be able to get to the
IP PBX with these 4 digits.
They can only exist in one switch.

You can change your system dialplan to look at the UDP extensions first and you
could dial 4 digits to get to the other switch but you would not be able to get
to the same 4 digit station in your switch.

You can change your system dialplan to look at the local extensions first and
you could dial 4 digits to get to the local extension but you would not be able
to get to the same 4 digit station in the other switch.
--------------------------------------------------------------------------------
3 different ways to dial and test this, they will all work provided the
programming is correct. After all testing is done, you can force UDP 4 digit
only, and AAR code + 7 digit, turn off Dial Access? y on TG 5 so nobody can
TAC dial.

1. TAC dial (I don't know TAC for Trunk-group 5) so using 105 as example
   This is also assuming you can TAC dial and TG 5 set to Dial Access? y

from a station, dial 105 7700

2. AAR dial (I don't know AAR code) so using 8 as example
   This uses AAR analysis routing

from a station, dial 8 999 7700

3. Uniform Dial Plan - (what you want in the end 4 digit dialing to IP PBX)
   This uses the udp tables. with local extension first, if you have a local
   extension 7700, it will not look at UDP tables.
   This will look at local extension first, then uniform dialplan, find the
   AAR routing, route to pattern 90, on to trunk-group 5 sending 7700 to far end

from a station dial 7700
