How to configure Konftel 300IPx for use with OpenScape Cloud

Last updated:

Tested model(s): Konftel 300IPx.

The conference phone has been tested with OpenScape Cloud with the following firmware: 2.7.28.

The instructions provided below are likely valid for other firmware versions or compatible devices but Unify will not validate it.

A 3rd party device configuration should be done by your ICT service partner or company administrator. Support from Unify for 3rd party devices is restricted to provide a generic configuration of OpenScape Cloud so that a device can be connected, and to operate the Cloud solution. If you have issues when setting up a 3rd party device, including its connection to OpenScape Cloud, or with its features and functions, please contact your 3rd party device supplier.

  • A Circuit domain administrator has assigned a phone number and desk phone to the user who will be using the phone.

  • Make sure you have the following SIP information:

    • User ID: this is usually identical to the phone number assigned to the user who will be using the phone.

    • User-specific password for SIP digest authentication.

    • SIP realm.

    • SIP server address and port.

  • Make sure you have the necessary certificate for establishing a secure TLS connection to OpenScape Cloud: RootCA.pem.

SIP information and certificate is obtained in self service from Circuit domain administrators who need to navigate to Administration > Cloud telephony and then select the user who will be using the phone.

To configure the phone for use with OpenScape Cloud, perform the following steps:

  1. Connect the phone to the network and power source.
  2. Reset the phone to its factory defaults, if it has residual settings from previous configurations:
    1. Press MENU on the phone (top center key with gear icon), and select SYSTEM > FACTORY RESET.
    2. When prompted, enter the administrative PIN code and press OK. The default PIN code is: 1234
    3. Confirm that you really want to reset the settings to default by pressing OK again.
    4. When the factory reset is completed, you are prompted to enter information to register an account. Press MENU on the phone to return to the idle screen.
  3. If DHCP is used in the network, the phone will automatically get an IP address from the network’s DHCP function. Check the IP address of the phone, as follows:
    1. Press MENU on the phone, and select STATUS > NETWORK.
    2. Find the phone’s network address under the heading IP ADDRESS.
  4. If DHCP is not used in the network, assign an IP address to the phone:
    1. Press MENU on the phone, and select SETTINGS > ADVANCED.
    2. When prompted, enter the administrative PIN code and press OK.
    3. Select NETWORK > IP > STATIC IP.
    4. Enter values for the IP ADDRESS.
    5. Enter HOSTNAME. Please ensure that it is unique.
