Use the Number Plan tab to specify the following parameters:
Parameter Description
Extension Number
Length
The number of digits for your extension numbering system. Valid entries are from
3 - 6. For example, extension 2001 and 4020 are
4-digit extension numbers.
Note: Once the first extension is configured, the extension number length cannot
be changed
without totally reconfiguring the system or deleting all the
extensions already configured.
Further, if a first digit dialed is assigned to extensions and you have set up
extensions beginning with that digit, you cannot change the digit
assignment without first deleting all affected extensions. For example, if 7
is assigned to Extension and you’re using extensions 7010, 7113, and so
on, you cannot reassign 7 to IP trunk access, without first deleting all the
7nnn extensions.
Default Password
The default password for newly created extensions is randomly generated by the
system. (When the password is changed, it must be four to eight digits in length.)
