Programming Esi-Link network dialing
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 IP Server 900 ESI Web 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 IP Servers 900 and ESI Communications Servers
1
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.
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 J.10).
4. Test some assigned network numbers.

For network numbering to function properly, ESI Communications Servers must be running compatible software.
