Handling call forwarding over extensions from two different PRIs

[comn8u]

We have two PRI blocks, with two sets of numbers.  When I try setting up call forwarding from an extension that exist on one PRI to forward to an extension on one of our other PRIs, it does not work.  I think I understand why it doesn't work, but need some direction. 

Example of phone numbers:
PRI #1: 535-334-6132
PRI #2: 774-224-6602

Each, of the two phones, are at separate facilities.  There is one user for both phones.  What would be the best way to handle calls to one phone?  The phone call handling would have to change based on the day the person is at each facility.  Both phones are Mitel 5330.

What would be a good way of configuring the call handling.

Thanks in advance.

1- Does one PRI exist in the same PBX or are they connected to different systems?
2- Can you forward to a DID number (outside call) to a number on the same DID blocks *or* can you forward off prem to anything, such as a cell phone?

If you can't forward off prem to any number then there could be several things that would apply.
An easy test here is to set up a system speed dial to the remote number - be sure to check 'over ride toll control' - and then forward to the system speed dial.   That will tell you if you have a COR issue.

The PRIs are coming into two different facilities and connected to two different Mitel 3300 controllers.

I did a test by calling my Mitel 5330 from my cell phone and was able to forward the call to an extension on another PRI (in the same building).

I also setup call forwarding from my phone to a phone that is programmed to a number on a different PRI and it worked.  So, I can setup call forwarding to a phone with PRI #1 number to another phone with PRI #2 number as long as they are in the same building.  If I try forwarding a call with the same situation, across buildings and between two different Mitel 3300 controllers, it does not work.  So, the clustered Mitel Controllers must be the issue.  If that's the case, how would I go around that or what would be your recommendations?

I'll see if I can test the following:

Since you're clustered then I'm lead to understand that you're not forwarding externally so the speed dial test doesn't have much value.

Two things I can think of here:
1- Check the COR of the incoming trunks to be sure it can dial across the cluster.
2- Check to see if your trunks are in different tenants.
3- Be sure you don't have interconnect restrictions that will block your PRI from using your IP trunks.

Ok- that's three things.

Not sure I understand exactly what you are trying to do here, that being said:

Do you have site-to-site dialing across IP trunks? I assume so since you are clustered. If so, does the person need two seperate DIDs? Could you use Hot desking and one DID to route between the phones when they log in?

Are you forwarding the inbound calls back out and to the other DID or are you trying to forward them across the IP trunks to the other extension?

If I am way off base here just ignore me.

All I want to do is either call forward from one extension to another through two different Mitel controllers or add a button on each phone that will flash when a call is coming in to the other phone.  If the phones reside in the same building, and on the same controller, I can do this.  For some reason, it does not work when trying to do this through another controller that's at another one of our facilities.  We have 5 Mitel Controllers (each at a different facility) and all are clustered. 

For instance:

Building #1: has extension: 4231 (full number DID: 234-634-4231) - resides on PRI #1
Building #2: has extension: 7342 (full number DID: 423-323-7342) - resides on PRI #2

If 4231 is ringing, I want to have 7342's phone able to receive the call forwarding or see the ringing flash on the phone.
If 7342 is ringing, I want to have 4231's phone able to receive the call forwarding or see the ringing flash on the phone.

if both of these extensions were located in the same building, I can make it work.  Right now, since these extensions are at different facilities and are plugged into different controllers, it does not work.  But, if I'm at either building location, I can dial either extension to reach the other phone.  I just can't call forward.

I'm not sure if I'm making sense about what I'm trying to do, so I need a little direction.  I did not set these controllers up, so my knowledge is limited.

I'm not sure if they are connected to the same PBX, but I don't think they are.

Where do I check to see if the trunks are under a different tenant and how do I check interconnect restrictions?

Mattmayn, I'm not sure how to get the answer to your questions.  Could you tell me where to look?

Thanks,

Disregard what I said about Tenants.  Not likely.
Do the speed dial test I suggested above.   Create a system speed dial with COR Over ride enabled that points to the remote extension number.   Then forward the local number to the system speed dial.

This will prove what I think it is - COR.

Oh, and also check your COS of your IP trunks.   Be sure it has Public Network to DPNSS allowed.

This is a COR issue.

Can you 4 digit dial between sites? If you are actually clustered you could put the extensions in a personal ring group

Can you delete the COR tables and test?

[comn8u]

I can dial any one of our 4 digit numbers (no problems with any extensions).  I'll look into the Personal Ring Group option.
