Description
Network numbering assignments are made using programming Function 342. Although Function 342 can be accessed via Installer mode programming on an ESI desktop phone, ESI strongly recommends using ESI System Programmer for this task when performing range and multiple assignments. Network numbers need to be assigned only once at one location in an Esi-Link network; the assignments are automatically applied to all ESI Communications Servers1 in the Esi-Link network. Each extension, mailbox, or department number that is to be assigned a network number must be unique throughout the Esi-Link network; therefore, it is almost always required that Function 341, flexible number assignment, be used to re-assign numbers at each location. Be sure you COMPLETE Function 341 BEFORE programming Function 342.
Rules
1. The local numbering plan always takes precedence over the network numbering plan.
Example: If extension 1200 is assigned at location 701, and the network number 1200 points to department 1200 at location 702, then callers dialing 1 2 0 0 at location 701 will always ring extension 1200; they cannot reach department 1200 at location 702 (unless they dial the full seven-digit Esi-Link number)
2. A number must be UNASSIGNED in Function 341 at all locations on the Esi-Link network EXCEPT the location with the extension, mailbox, or department that is to be assigned the network number.
Preparation
To support four-digit network dialing, all locations must be programmed with four-digit numbering plans. ESI does not recommend using three-digit dial plans, because the total number of available numbers for network dialing would be fewer than 100 (e.g., a fully populated ESI-200 with a three-digit dial plan will offer only 44 unassigned numbers that can be allocated for network numbering).
The simplest way to implement network numbering is to first perform the appropriate flexible number reassignments in Function 341 at each location in the network.
To complete this, you must perform the following tasks:
1. Perform flexible numbering assignments.
2. Assign network numbers to the necessary Esi-Link locations.
3. Print out the network number report to use as reference, using Function 76 (see page K.10).
4. Test some assigned network numbers.

Programming
1. Perform flexible numbering assignments
Here, you’ll be using Function 3411 to reassign the numbers in each system.
1. Use ESI System Programmer to connect to the first system in the Esi-Link network.
2. Select F341, Flexible Number Assignment. Exchange all extension numbers that are to be assigned to the remote locations with unassigned numbers.
Here’s how:
Range reassignments
a. In the New Type field, select Unassigned.
b. In the Old Type field, select Extension, Department, or a mailbox type.
c. Check the Range checkbox.
d. Select the range of old numbers and an equal quantity of new unassigned numbers, and click Exchange to confirm.
Individual number assignments
a. In the New Type field, select Unassigned.
b. In the Old Type field, select Extension, Department, or a mailbox type.
c. Select the old number and the new number to be assigned, and click Exchange to confirm.
d. Continue steps b through d until the number reassignments are completed.
3. Use ESI System Programmer to connect to the next system and repeat step 2.
2. Program network numbers
1. Launch ESI System Programmer, and connect to one of the ESI Communication Servers on the Esi-Link network.
2. Access Function 342.
3. Populate the network number list by either:
a. Clicking the checkbox for populating the number table with a range of numbers, and then entering the starting and ending numbers.
or
b. Leaving the checkbox unchecked, to select the dialing plan(s) to use to populate extensions from selected dialing plans.
4. To complete populating the network number list, click Add Filter Numbers.
5. To select a range of numbers, choose the numbers to be assigned to the first location by clicking the first network number and, while holding down the Shift key, dragging the mouse.
6. Next, right-click a location field (or “cell”). An Esi-Link location list will appear. Select the location to which the selected numbers are to be assigned, and click the check mark icon.
7. Repeat steps 5–6 to assign network numbers to other locations in the Esi-Link network. (For numbers that you won’t be using, leave the location number blank.)
8. When finished with this operation, click Save and send programming changes to the system.
3. Print a network numbering report
After sending the programming changes, you should generate a report of the network number assignments. It will be used both to verify network number programming and for reference. Here’s how to generate the network numbering report:
1. In ESI System Programmer, select F76 and click Run.
2. When the report is displayed, print a copy for each location in the network.
3. Keep the printouts for use as checklists when performing flexible number reassignments in Function 341 at each location.
4. Test some assigned network numbers
When you’ve finished the previous steps, test by dialing some network numbers assigned to extensions at remote locations. They should ring. If they don’t, follow the steps in
