Article Summary

Dialpad is proud to support Polycom deskphones, both with and without Obi firmware.

Let's go over how to configure Poly devices to set you up for success. 

Obi Firmware Compatibility

Due to the global chip shortage, Poly re-chipped their VVX 150-450 phones, meaning newer inventory no longer works with Obi. First things first, you'll need to check and see if your device is Obi-compatible.

Check For Obi Compatibility

Discover if your device is Obi-compatible or not by checking the hardware Revision Code — this is located on the sticker on the back of your phone (the same sticker contains your Mac Address).

Incompatible revision codes are ZZA, as well as ZA, ZD, ZH (though those three are less common). Any other hardware revision code should be compatible with Obi.

Any other hardware revision should be compatible with Obi.

Your Polycom phone must be on the list of Supported Desk Phones and use the listed firmware version before proceeding with these steps.

Factory Reset

Before starting the provisioning process, a simple Factory Reset (also known as a hard reset) is recommended to ensure any previous configuration does not interfere with your Dialpad service.  Don’t worry, it won’t remove the device’s operating system, it will just set everything back to its original settings. 

To reset your Poly Obi Edition device from a browser:

Open a browser to display the Poly Obi-Edition phone’s web interface

  1. Navigate to System Management
  2. Navigate to Device Update
  3. Navigate to Reset Configuration at the bottom of the page
  4. Select Reset then OK to confirm the operation

To reset your Poly Obi Edition device from the phone:

  1. Press the Home button
  2. Use the directional arrows to highlight Settings 
  3. Press the center Ok button
  4. Press the softkey marked Factory Reset
  5. Enter the Admin Password for the device

Provision to Dialpad

If your Device is confirmed to be an Obi-revision model and has Obi FW already, setup is accomplished by accessing the Local IP and configuring the phone’s settings on the web server on that IP.

  1. With the device on, press the Home button and access Settings
    • Record the IP address
  2. Access the IP address in a new browser tab using HTTPS, as HTTP is unlikely to work
  3. Navigate to System Management 
  4. Select Auto Provisioning
  5. Under Auto Provisioning, the ITSP Provisioning section must be manually configured
    • Uncheck the boxes beside Method, Interval, and ConfigURL
    • Set Method to: System Start
    • Set Interval to: 0 (zero)
    • Set ConfigURL to: (the terminating backslash is required)
  6. Select Submit


My phone rebooted multiple times, is this okay?

Yes. A successful result will see the phone reboot several times, possibly update firmware, and then show “Dialpad Activate” on line 1 in the top left of the screen.  

How long does provisioning take?

If a firmware change is required, this can require 8-10 minutes to complete, otherwise, a normal provisioning can be done in roughly 2-3 minutes.
