Two ways to customize configurations of your SIP-T23P/T23G IP phone:

● The user interface on the IP phone. ● The user interface in a web browser on your PC. The hardware components keypad and LCD screen constitute the phone user interface, which allows the user to execute all call operation tasks and basic configuration changes directly on the phone. In addition, you can use the web user interface to Overview access all configuration settings. In many cases, either the phone user interface and/or the web user interface interchangeably. However, in some cases, it is only possible to use one or the other interface to operate the phone and change settings. You can customize your phone by pressing the Menu soft key to access the phone user interface. The Advanced Settings option is only accessible to the administrator, and the default administrator password is “admin” (case-sensitive). For more information on customizing your phone with the available options from the phone user interface, refer to Customizing Your Phone on page 21. In addition to the phone user interface, you can also customize your phone via web user interface. In order to access the web user interface, you need to know the IP address of your new phone. To obtain the IP address, press the OK key on the phone. Enter the IP address (e.g., http://192.168.0.10 or 192.168.0.10) in the address bar of web browser on your PC. The default administrator user name and password are both “admin” (case-sensitive). The options you can use to customize the IP phone via phone user interface and/or via web user interface are listed in the following table: Options Phone User Interface Web User Interface Status --IPv4 --MAC --Firmware √ √ --Network --Phone --Accounts Basic Phone Settings --Contrast √ --Backlight √ --Language √ --Time & Date √ --Administrator Password √ √ --Key as Send √ --Phone Lock √ --Ring Tones √ --Contact Management --Directory x 7 User Guide for the SIP-T23P/T23G IP Phone 8 Options Phone User Interface Web User Interface --Local Directory √ --Blacklist √ --Remote Phone Book x --Call History Management √ --Logo Customization x --DSS Keys √ --Account Management √ --Dial Plan x --Emergency Number x --Live Dialpad x --Hotline √ Basic Call Features --Recent Call In Dialing x --Auto Answer √ --Auto Redial √ --Call Completion √ --ReCall √ -- Do Not Disturb (DND) √ --Call Forward √ √ --Call Transfer √ --Call Waiting √ --Conference x --Call Park √ --Call Pickup √ --Anonymous Call √ --Anonymous Call Rejection √ Advanced Phone Features --Busy Lamp Field (BLF) √ --BLF List x --Call Recording √ --Hot Desking √ --Intercom --Multicast Paging √ x √ --Music on Hold x --Automatic Call Distribution (ACD) x --Shared Call Appearance (SCA) x --Bridged Line Appearance (BLA) x --Messages √ SIP Account --User Options x √ --Active Line √ Options Phone User Interface Web User Interface --Label √ --Display Name √ --Register Name √ --User Name √ --Password √ --Server Options --SIP Server 1/2 √ --Register Port x --Outbound Status √ --Outbound Proxy1/2 √ --Proxy Fallback Interval √ --NAT Status √ Note Overview The table above lists most of the feature options.
