The extensions and voice mailboxes affected by the new numbering system are listed
in the following table.
Unit ID 1 Unit ID 2 Unit ID 3 Unit ID 4
Local Extensions 111-118 121-128 131-138 141-148
Remote Extensions 211-218 221-228 231-238 241-248
Local Mailboxes 111-118 121-128 131-138 141-148
Remote Mailboxes 211-218 221-228 231-238 241-248
General Mailboxes 410-419 420-429 430-439 440-449
As you may have noticed, none of the Extension Ring Groups are affected since they
are global to the entire system. It doesn’t matter if there is one or four TalkSwitch
units on a LAN, there will always be 10 Extension Ring Groups with the extension
numbers 300-309.
1.5.5 Keeping track of the lines and extensions
To keep track of the extensions and lines connected to each TalkSwitch, you may
want to label each unit with it’s respective Unit ID. This will simplify matters when it
comes to adding or removing extensions and lines.
In the event the TalkSwitch units are located in a room away from the extensions and
you need to identify which unit is which, there is a utility in the configuration
software that will allow you to identify each unit by flashing the lights on the front
panel. When the configuration software is opened, you can check details of the
TalkSwitch units on the LAN by clicking on the ‘LAN Details’ button.
In the pop up window, you can select a Unit ID, then click the Identify button to have
the lights flash on that unit. The lights will stop flashing when you click ‘finished’ or
5 minutes have elapsed.
1.5.6 Optimizing the system for networked use
TalkSwitch is designed to be as robust as possible for the price point. Keeping this in
mind, there is a limitation as to how many calls can be placed across the LAN from
each unit. This is known in the industry as a blocking architecture.
Each TalkSwitch unit can support up to 6 simultaneous calls through it’s LAN port.
This technique allows the systems to work as they should more than 99% of the time
since it is rare that more than 6 calls would need to cross from one unit to 1 or more
other units simultaneously. With the current design, this means that a total of 12
calls (using 4 units) can run simultaneously across the LAN.
