Configuring Siemens C470IP with 3CX Phone System

IMPORTANT This guide has been tested with firmware version 021840000000 / 041.00 and EEPROM Version 1.4. Be aware that different firmware revisions may have different web interface formats and functionality.

  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 Siemens C470IP phone to the network and mains power supply. The phone will boot up, and providing you have DHCP installed on your network. (IMP Note: This FAQ is based on a phone that is set to factory defaults.)
  3. To obtain the IP address assigned click on the right hand option of the joystick button, and scroll down to ‘Settings’ and click OK.
  4. Scroll down to ‘Base’ and select OK. Scrolling down the menu you will find a ‘Network’ option. Once you OK this option all the network information will be displayed.
  5. Now point your browser to the web interface of the phone: 'http://<phone-ip-address>' where is the IP address shown on the phone.
  6. Enter the system PIN of the phone and click ok to access the phone’s configuration. The default PIN is ‘0000’.
  7. The configuration will now display 3 tabs, namely Home, Settings and Status. Enter the ‘Settings’ node to start configuring the phone.
  8. In the ‘IP Configuration’ node, all defaults may be retained, unless you wish to specify a fixed IP.
  9. Click on the ‘Telephony’ node to access the phone configuration.


     
  10. The ‘Connections’ node will allow the configuration of the device, which allows various IP connections / profiles.
  11. Click on the Edit button next to the Profile you wish to configure.


  12. In the ‘Connection name or number’ enter ‘3CX Phone System’.
  13. The ‘Authentication name’ , ‘Authentication password, ‘Username’ and ‘Display name’ fields should be populated with the extension information as defined in 1 above.


  14. Click the ‘Show Advanced Settings’ option.
  15. The ‘Domain’ field needs to be populated with the same domain entry that appears in the 3CX configuration > General settings > Settings for Direct SIP.
  16. In the ‘Proxy Server Address’ and ‘Registrar Server’ enter the IP address of your 3CX server.
  17. Click on ‘Set’ to apply the changes and start making calls.

Note1:
Our tests indicate that the phone will use its own music on hold, rather than that offered by 3CX Phone system.

Note2:
If you have problems when transferring calls using this phone, disable “Supports Replaces” from within the PBX. This is done from 3CX Web Interface by editing the extension and going to the "Other" tab.
