This is currently only supported by our Polycom phones when enabled, and allows you to send a page to one or more phones.
Each
phone can be setup with a single list of extensions to page. This will
normally be setup when your phone system is installed, but can also be
modified on the MyPhone portal in the Enhanced Services by entering a comma separated list of extensions to page in the Speakerphone Page dialog.
To page the group of extensions defined under Enhanced Services, dial *399.
To page a single extension, dial *400 followed by the extension to page. i.e. *400201.
Two Way Speakerphone Paging
Two way paging allows you to page a single extension, and start a two way conversation through the dialed phone. To start a Two Way Page, dial *400* followed by the extension to page. i.e. *400*201
