How to access settings


Also, there are some global settings for the phone, as well as policies that control certain features that can be enabled or disabled.

  1. Go to Zoom’s web portal and sign in.
  2. The Navigation Menu should have a section called Phone System Management followed by a section called Users & Rooms.
  3. Depending on your preference, you may select Zoom Rooms or Cisco/Polycom Rooms.
  4. You can adjust settings for a room by clicking its name.
    Here are the options and information you will see:

Profile tab

  • Site (only visible if you have multiple sites):
  • The site to which the room belongs is displayed. Move the room to another site by selecting another site from the drop-down menu.

  • Extension Number:
  • Changing the extension number associated with a room can be done by clicking on the Edit button.
  • In some cases, extension numbers can’t be used due to the fact that they are reserved. There is a limit of six digits for extension numbers. It is possible for extension numbers to be 2 to 5 digits if you have multiple sites and enabled site codes, and site codes can be between 1 and 2 digits if you have multiple sites.
  • Number(s):
  • The direct phone numbers can be assigned to a room by clicking on the Assign button. There is only one setting that is visible if a package has been assigned to it.
