Set Up Multiple Provisioning Servers

You can configure multiple (redundant) provisioning servers—one logical server with multiple addresses.

You can set up a maximum of eight provisioning servers.

You must be able to reach all of the provisioning servers with the same protocol, and the contents on each provisioning server must be identical.


  1. Power on the phones and connect them to your VoIP network using a Power over Ethernet (PoE) switch or external adapter and a network cable.
  2. Create a root FTP directory on the provisioning computer with full read and write access to all directories and files.

    This is where you need to place configuration files.

  3. In your FTP server application, create a user account for the phone to use and take note of the user name and password.
  4. Launch the FTP application.

    You must keep it running during provisioning so that the phones can communicate with the UC software.

  5. Download Polycom UC Software from Polycom Support and uncompress the files into your root FTP directory.

    You can choose the combined UC software package or the split UC software package.

    • The combined version contains all files for all phone models.
    • The split software package is smaller, downloads more quickly, and contains sip.ld files for each phone model, enabling you to choose provisioning software for your phone model(s) and maintain software versions for each model in the same root directory.
  6. Map the provisioning server DNS name to a unique IP address for each server.
  7. Configure the following settings:
    • Number of times a file transfer tries each server
    • How long to wait between each file transfer attempt
    • Maximum number of servers to which you want to try to transfer files
