Phone access using the web UI

Last Updated : Apr 17, 2026 |
Prolog information
Use the web UI to access specific phone administration procedures. Avaya J100 Series IP Phones have an embedded web server that provides a browser-based web UI for phone administration.
To enable the web UI, enable the web server on the phone, define the login password, and set the port number. If you do not define the web UI password, the user must define it during the first login.
To restrict users from accessing the Web UI administrative procedures and changing the phone configuration, define a new password in the FORCE_WEB_ADMIN_PASSWORD parameter. The new password must comply with the following rules:
  • The password length must be between 8 to 31 characters.
  • The password must contain at least one numeral, alphabet, and special character.
    The allowed character classes are: numeric, upper case alphabet, lower case alphabets, and special characters.
    The allowed special characters are tilde (~), exclamation mark (!), at (@), pound (#), dollar ($), percent (%), carat (^), ampersand (&), asterisk (*), underscore(_), minus (-), plus (+), equal (=), back quote (`), pipe (|), back slash (\), parenthesis (()), braces ({}), brackets ([]), colon (:), semicolon (;), quote (“), single quote ('), lesser than (<), greater than (>), comma (,), period (.), question mark (?), and forward slash (/).
  • The password must have a maximum of four consecutive characters from the same character class.
  • The password must have a maximum of two consecutive identical characters.
The following are the web UI configuration parameters:
