There has been a change in the behavior of how the Call Waiting number is displayed.



The old behavior 

  1. "Call Waiting Indication (CWI)" If Call Waiting is enabled ("on", "visual only", "ringer") the incoming caller extension is displayed in the lower left corner of the display. A short knocking signal can be heard simultaneously in the background of your current active call indicating another incoming call.


The new behavior

  1. "Call Waiting Indication (CWI)" If Call Waiting is enabled ("on", "visual only", "ringer") the incoming caller extension is displayed of the next screen by pressing the arrow - -> context sensitive key in the lower right corner of the display. A short knocking signal can be heard simultaneously in the background of your current active call indicating another incoming call.


        Unfortunately, in newer versions it is not possible to have the full old behavior (show both current caller ID and new incoming caller ID at the same time). However, it is possible to disable setting http://wiki.snom.com/Settings/always_show_active_call in order to display the new incoming caller ID instead of the the current caller ID when the new call comes. Setting "always_show_active_call" can be changed by using provisioning or a simple HTTP request: http://wiki.snom.com/FAQ/Can_I_set_single_phone_settings_via_HTTP_requests

Starting with 8.7.5.9 Call Waiting setting is per identity.
