      Polycom OBI Adapter Guide (Classic)

      This article describes the configuration of most Obi adapters in case they are used for analog phones. The difference in models will be in codec supported, which is represented at the end of this guide.

      Accessing the web interface

      Connect the adapter to the network and find the IP address using network scanning software like Netscan (Windows) or Angry IP scanner (Mac).

      To edit an item in the Web interface, you will need to uncheck a Default checkbox near it.

      After you modify some values under ITSP you will see a prompt to reboot the phone. Only do it at the end of the configuration.
