Configuring SNOM 300-320-360-370-SIP for 3CX Phone System

IMPORTANT This guide has been tested with firmware versions 6.5.15 & 7.1.30. Be aware that different firmware revisions may have different web interface formats and functionality. See compatibility list for latest phone firmware revisions that we have tested with 3CX Phone System.

  1. Ensure that you have created the extension that you wish to use with the phone in 3CX Phone System first. Take note of the ID field and the password that you have entered for the extension.
  2. Connect the Snom phone to the network and main power supply. The phone will boot up, and providing you have DHCP installed on your network, will obtain an IP and display it at the bottom of the phone’s LCD screen.
  3. Now point your browser to the web interface of the phone: ‘http://<phone-ip-address>’ where is the IP address shown on the phone.
  4. Enter the password of the phone and click login to access the phone’s configuration. For this particular phone, the default password to reach administrator mode is “0000”

  5. Click on ‘Identity 1’ on the left pane under Setup category so you can configure the phone. (Refer to figure 1)
  6. First make sure that ‘Identity active’ under Identity 1 is set to On.
  7. In the “Display Name” field enter the name you want to be displayed on the Phone display.
  8. Now proceed by entering in the “Account” field which is the extension you want to associate with this phone. This should match the “Extension number” field in the User Information section of the ‘Add Extension’ page in the 3CX Management Console
  9. Enter a password for the account in the “Password” field. This should match the “Password” field in the Authentication section of the ‘Add Extension’ page in the 3CX Management Console
  10. In the Registrar field, enter the IP or FQDN of the 3CX Phone System server. If entering an FQDN, review this FAQ.
  11. Repeat the same setting for the Outbound Proxy option
  12. In the “Authentication Username” field enter the authentication ID. This should match the “ID” field in the Authentication section of the ‘Add Extension’ page in the 3CX Management Console
  13. Now press “save” to save all changes which is on the bottom of your configuration screen. Your phone will register with the 3CX phone system. You can verify that on the Phone System\Line Status page of the 3CX management console.
  14. If you want to configure additional lines, please repeat steps 5 to13 providing that you have additional extensions created on the 3CX server.


Configuring BLF (busy lamp field) on a SNOM phone and 3CX Phone System v5

To configure BLF on a SNOM phone one needs to access the phone’s web interface via a web browser. In our example it is assumed that the phone has IP address 10.172.0.104 and the 3CX Phone System in installed on IP address 10.172.0.2.

Click on “Function Keys” on the left to access the “Key Settings” page. Go to the lower part of the screen and select the position/lamp to configure on the device. In this example we are configuringposition 8. From the “context” field select the identity from the drop down list that will be monitoring the status of the other extension(s). In the “Type” field select type “Extension”. In the “Number” field type the number of the extension you wish to monitor, followed by the IP address of the 3CX Phone System. In our example we want to monitor extension 121 and the server IP is 10.172.0.2, so you must enter “121@10.172.0.2”. Then click the “Save” button. BLF is now configured.

NOTE:
* This feature (BLF) is not available in the Free Version of 3CX Phone System. The MWI feature is available in all other versions.
** This was tested and configured on a Snom 320 with the following system information:
Application-Version: snom320-SIP 7.1.30
Rootfs-Version: snom320 jffs2 .36.
