Typically, you want to have the lowest extension number associated with
the first port, the next highest extension number associated with the
second port, and so on.
To reassign the extension numbers:
1 Record the extensions and either the MAC addresses or port numbers for
the four Line Card ports.
2 In the NBX NetSet Menu window, click Reports > Device List .
3 Click on the Extension column heading to sort the list by extension from
the lowest extension. Click the heading again to sort from the highest
extension.
4 Review the extensions in the list to find the highest extension number
that has been assigned. Add one to that extension and record it. For
example, if the highest assigned extension number is 7268, you record
7269.
5 Click PSTN Gateway Configuration > Analog Line Cards .
6 From the four Line Card ports you recorded, click the extension number
of the port with highest MAC address or port number to open the
Modify
screen.
7 Change the extension number (7258 in this example) to the extension
number you recorded when you were viewing the Device List tab (7269).
8 Click OK . The Line Card Ports tab reappears showing the new extension
number. Extension 7258 is now unused.
9 From the four Line Card Ports you recorded, select the port to which you
want to assign the unused extension. In the example, 7258 is the lowest
extension number of the four, so select the port with the lowest MAC
address or port number and click its extension.
10 Change the extension number and click OK.
