Thomson ST2020 IP Phone could be configured in two different ways. The first one is through the telephone itself by using the LCD displayed and the softkeys. The second way is to use the through your web browser by using the phone's web interface.

The configuration through the web interface is separated into two levels of access - user and administrator. They are giving different rights and possibilities for changes and configurations, to the user.

First lets see how we can make configurations through the phone device.

The phone has 3 soft buttons, which are used to perform different operations. They are: Vol -, OK and Vol +. In order to make changes in the configuration, you have to press the button labeled with menu. Once you press it you will be able to choose between two possible options - Info and Config.

If you want to see information about the phone's IP address, Status or Version, then you have to choose Info. Press the Vol - softkey and you will see the following three options: IP, Status, Vers. To check the current phone's IP address, press the Vol - softkey. To check the phone's status, press the OK softkey. The status could be either Succeeded or Failed. To check the current firmware version, press the Vol + softkey. Use the button labeled with C, if you want to go back or quit from the menu.

If you choose the Config option, you will be able to change the phone's configuration. Press the Vol + softkey. The phone will turn in Config mode. You have to wait a few seconds until you see the following message: Ready for Config and the phone's IP address. You have to press the Menu button again. You are now at the configuration menu. It is separated in several parts (pages).

On the first page you could choose between Acct (change the authentication's username and password), Phone (Volume and Call Forward) and Next (go to the next page). You could select the desired operation by pressing the corresponding softkey, placed under the options. For the left option (Acct) press the Vol - softkey, for the middle one (Phone), press the OK softkey and for the right option (Next), press the Vol + softkey. These rules are valid for all pages.

On the second page the options are: Speed (configure the speeddial buttons), User (change the username and password for the user level of access) and Next (go to the next page).

On the third page you have Boot (reboots the phone), Admin (gives you access to the Advanced options) and Home (return to the first page).

So let's take a closer look at the options.

The Acct section allows you to change the username and password used for authentication at the Asterisk server. Once you select the Acct menu, you will see the Acct submenu where you could change either the authentication username or the authentication password.

If you want to switch between capital letters, small letters and numbers, you have to use the Vol + softkey. Unfortunately, the current state of the keyboard is not shown anywhere on the LCD display, so you have to check it by pressing some of the keys.

If you type a wrong character, you could erase it by pressing the Vol - softkey. Do not use the C key, because it will return you in the previous menu.

The Phone section allows you to change the outgoing volume of the speaker and the incoming and outgoing volume of the handset (respectively headset). Also, you could change the Type and the URL (phone number) for the call forwarding.

If you want to change the settings for the speeddial buttons or the username and password for the User access level, then you need to go on the second page by pressing Next (use the softkey Vol +).

So, from the second page you could choose between the Speed and the User menus. Through the Speed one you could change the numbers for the five speeddial buttons.

Through the User menu you could change either the username or the password used for the User level of access (used through the web interface).

On the third page you could choose between Boot and Admin. The purpose of the first one is just to reboot the phone device. The system will ask you for confirmation. If you agree - press the softkey, which corresponds for Yes (Vol -) or if you disagree press Vol +, which stands for No.

Now, about the Admin section we will need to take a closer look.

First of all, if you want to make changes in the Administrator section - you will need the Administrator password. By default it is 784518. In order to input digits you will need to change the state of the keypad. Press the Vol + softkey twice. Once you enter the correct password, you will be able to change the following settings: Network, SIP, Media, Advanced, Phone and Reset. These options are again separated in three pages. The Network and the SIP are placed on the first page. The Media and the Advanced options are placed on the second page and on the third one there are the Phone and the Reset options.

Through the Network menu you could enable/disable the DHCP (the phone will take its network configuration from a DHCP server), you could change the IP address (DHCP disabled), the default subnet mask (DHCP disabled), the DNS server and the NTP server.

In the SIP section you could set or change the IP address of the SIP Proxy and the Outbound Proxy. The so called Display Name, which actually is the CallerId, could be changed from this section. The last option here is the User, which into this section actually means: the name that will be displayed on your phone's screen. That's it for the sections and the options on the first page from the administrator section.

Now let's go to the second page. The sections here are: Media and Adv (Advance). The media section allows you to choose the preferable codec and to enable/disable the VAD (Voice Activity Detection). By default the preferable codec is G.711 Alaw. The other options are: G.711 ulaw, G.723 and G.729. By default the VAD is disabled and it should be in this way when you are using the phone with the Asterisk. The Adv section allows you to enable/disable the VLAN (802.1q) and to change the number of the Auto Dials.

The sections on the third page are: Phone and Reset. Through the first one you could change the Time Zone, to change the Daylight settings (+1, -1, No), to change the Tone (could be France, Germany, Spain, USA, UK, Slovenia) and you could set the Voicemail number at which you receive your voicemail messages.

The second section - Reset - allows you to reset the phone device to the factory default settings. Possible options are Yes or No.

Once you are ready with the configuration, you have to reboot the phone. Use the Boot section from the Configuration menu. If all the settings are correct the phone will boot quickly and it will be ready to be used.

Configurations through the Web Interface

As we already mentioned there are two levels of access - User and Administrator. If you would like to log in as User, then use the username user - no password is required and of course your rights will be limited.

As a User you will be allowed to change the username and password only for the User account.

The user rights include the change of the authentication username and password used for authentication with the Asterisk server and the change of the numbers set for quick dial.

Apart from the Administrator account the User could only enable/disable the Call Forwarding function and to change the Call Forward number. You will not be allowed to change the Voicemail number.

The volume levels for the speaker and the handset (headset) could be also adjusted.

The Administrator has full access and the right to change everything. However, to enter as administrator, it is required to put the phone in Config Mode. Also you will need to enter the administrator password. By default it is 784518.

As Administrator you will be allowed to upgrade the firmware, to change the usernames and passwords for the User and Administrator level of access, to restore the default factory settings, to change the network options, to change the options connected with the SIP Server such as codecs, authentication accounts and VAD. You could adjust the Time Zone, Country Tone, Speaker and Handset volume, the VLAN settings and the Speeddial buttons. The Voicemail and Call Forward numbers could also be changed.
