Yes, it is doable but there are several considerations.

Are these numbers DID numbers in the old switch? If so, all their calls will come into the old switch and have to be sent to the new switch.

In the new switch if the stations are within the dialplan for that switch just add them like any other phone.

I need to know the software release of the old switch before I can tell you how to specifically route the call from the old switch. Each version does it a little different. Since you are already dialing four digit (or whatever your station length is) between the systems now, all you will be doing is what you already do to get calls from one PBX to the other now.

Also, are you using AAR or UDP to route calls?

Dear Marty,

thanks for the reply,following are the answers for your questions
1.Yes,These are DID numbers in old switch,so you mean to say like we need to Fast Forward the Extns to new switch.

2.In the new switch if the stations are within the dialplan for that switch just add them like any other phone.--i did not understood what is means...?we are adding new digital card into switch to add new extns...but there are existing dial plan for other working extns.it is not complete new switch...

3.both swtich are having same versions Ge Version:V12.

4.we are using AAR to route calls.

Thanks a million.
PS.

For question 2.

Let us say that the station number that is moving from the old PBX is 3120.

In the new PBX can you type "add station 3120" and get to the station screen or do you get an error message saying you can't do this.

If you get to the station screen then that number is in your dialplan in the new PBX, if you get the error message then the station number is not in the dialplan.

Hi Marty,

that is fine,we dont have that Dial Plan in switch B,so you mean to say we need the dial plan in switch B as well.but as you know our rek is to bring the Extns present in switch A to Switch B where both Switch A and Switch are connected together and they can call Extn to Extn...so i think we need to do some prog in switch A and might be in switch B as well...or do you think,we can use the Trunk pairs and no need to connect those extns to switch B at all...is it possible like that...we have T1 24 channels PRI line which is connecting Switch A to Switch B....pls advise...thanks.

Your question is a little confusing so I will answer what I think you are asking.

What I think you are asking is how do you dial extension to extension between two PBXs using an ISDN-PRI T1 that is tying the two machines together.

First you will need to have Universal Dial Plan active in both machines. Type "display sys cust", the list is alphabetical so look for a "y" after the above choice. If it is not, then contact Avaya and get the feature turned on.

Next you need to make the dialplan identical in each PBX and any conflicting numbers corrected (these will be the same number in use in both machines), each machine must be unique. Now make sure there are no conflicting TAC, FAC, or DAC codes. If there are then they also need to be changed.

We will make it simple for the Universal Dial Plan, you can add more to this to match your exact configuration. Switch A has an extension range of 2000-2999 and switch B has 3000-3999. In switch A type "change uni 3". In this field type 3 in the first column, 4 in the Len column, 0 in the Del column, leave Insert Digits field blank, aar in Net column, n in Conv column. Now save this.

Type "add aar an 3". Put 3 in the first column, Min/Max of 4, choose a route pattern (I choose 100 for this), Call Type is aar. Now type "change rou 100". In the first field put the trunk group number of the group tying the two machines together with an FRL of 0.

In switch B do the same thing but use 2 instead of 3.

Now test it. When you dial 3xxx from switch A it should ring that phone in switch B.

This is a simple overview. You can be very specific on the Universal Dial Plan form, you can get right down to the individual stations. Don't do that normally because the form does have a finite size. I could give some examples but lets not complicate life just yet.

Dear Marty,

thanks a lot...ur simply gr8 help..also i have one more important question that some extensions currently working in switch A needs to be moved to switch B but users dont wanna change the existing extensions numbers to the new extension numbers provided by switch B...they want to keep the same existing extension numbers.....how can i achieve this...thanks.

Regds,
PS.

Yes, if you have Universal Dial Plan activated.

The call will still ring in on the PBX they left and will go over the tie to the new PBX. You are going to need to monitor the traffic over that T1 to make sure there is not too much because then you will get call blocking.

If you are consistently running at 75% capacity it is time to add another one.
