Context Sensitive Conferencing

Last Updated : Aug 30, 2026 |
On 1400, 1600, 9400, 9500, 9600, and J100 Series telephones there have been changes to the display and handling of calls put on hold pending transfer. For those phones there have also been changes to which calls are conferenced when a Conference button or Conf display option is pressed on the telephone.
  • Previously, pressing Conference would put the user's current call and all held calls into a conference. That included any calls that had be put on hold pending transfer by pressing Transfer.
  • The result of pressing Conference on the telephone now depends on which call is currently highlighted on the phone display and what other calls are held or held pending transfer.

Note that this new behavior only applies to conferences being initiated from the telephone. The original behavior of conferencing all calls still applies if the conference function is initiated from elsewhere such as from an application like one-X Portal.
  • Changing which call is currently highlighted
    On phones with a set of cursor keys (four cursor keys around an OK key), the up and down cursor key can be used to change the current highlighted call (or call appearance if idle). This can be done even whilst there is a currently connected call. On touchscreen phones, the cursor buttons on the right-hand edge of the screen can be used for the same purpose.
    The method of highlighting is:
    • 1400/1600 Series Telephones
      On these phones only details of a single call are shown on the display at any time. The displayed call is the currently highlighted call.
    • 9400/9500/9600/J100 Series Telephones
      On most phones in these series, the background of the shading is changed for the currently selected call. The exceptions are 9611, 9621, 9641, J159 and J179 telephones where a yellow symbol is shown on the right of the highlighted call.
