How To Create A Mitel 3300 IP Loopback Trunk

1) Network Elements

This Network Element will be/is your local PBX. Note: if this 3300 is already in a cluster then these fields are already filled in.

Assign a Name

Select type of “3300 ICP”

Enter the IP address of the local PBX. (The one you're logged in to.)

Enter a PBX Number/Cluster Element ID

2) Trunk Attributes

Edit an unused Trunk Service Number. This TSN will be assigned to your new loopback trunk.

Enter '0' for in the “Dial In Trunks Incoming Digit Modification – Absorb” field.

Enter “LoopBack” in the “Trunk Label” field.

3) ICP/PBX Networking

Enter the ICP/PBX Number. It is recommended that you use the same number as the Cluster Element ID number used in step 1.

Select YES for the “Local ICP/PBX” entry.

In the “Max Number of VoIP Calls” field enter a number greater than the expected number of active calls. Maximum is 2000.

For Clarity, in the “Comment” field enter “LocalPBX”.

4) IP/XNET Trunk Profiles

Create a new IP/XNET Trunk Profile.

In the “Trunk Service Number” field enter the TSN created in step 2.

In the “Interconnect Number” field enter the number “1”.

In the “Remote Profile Number” field enter the exact same number as the Local Profile Number. This must match.

In the “Comments” field enter “LoopBack”

5) IP/XNET Trunk Groups

Create a new IP/XNET Trunk Group by selecting an unused entry.

In the “PBX Number” field, enter the PBX Number created in step 1.

In the “Local Profile Number” enter the LPN created in step 4.

In the “Comments” field enter “LoopBack”.

6) ARS Digit Modification Plan

Select an unused Digit Modification Plan. The entries made here regarding the “Number of Digits to Absorb” and the “Digits to be Inserted” will be specific to your own applications. For our example we will not be absorbing or inserting any digits.

7) ARS Routes

Create a new ARS Route.

Select an unused ARS Route.

In the “Routing Medium” field select “IP/XNET Trunk Group”.

In the “Trunk Group Number” field enter the IP/XNET Trunk Group created in step 5.

In the “COR Group Number” field enter the number '1'. This should be unrestricted.

In the “Digit Modification Number” field enter the Digit Mod Number created in step 6.

8) ARS Digits Dialed

Your new loopback trunk is now available and ready to use. You may now point ARS digits dialed to your new loopback route. Note: for this How-To we did not absorb or insert any digits in the digit modification table. It is is expected that you will need to in order for your application to work.
