Changed Behavior Changes

snom715 & snom710
Usually 'busy' is indicated via a red solid light and 'available' via a green one. This cannot work for LEDs that only light in one color. So this now got repaired for 710/715 which only light in green. We introduced a new setting 'led_colors_used_for_green_only_leds' that controls which color will actually cause the green LED to light up (previously color was ignored and green LED always lit). Also we adapted the setting 'led_red' so that states 'calling' and 'holding' are no longer assigned fix to red but rather to default-color, which is red on multicolor-LEDs but green on 710/715 monocolor line-keys. Also we included state 'unavailable' into the red-list to make sure it won't be signaled on a green LED. I.e. the new concept for the green monocolor line-LEDs is, they light up to signal availibility but stay off when the other side is busy. By default this new behaviour is enabled, which can be adjusted via the available settings. Changes

SCPP-5218: It is possible to play back multicast audio through speaker now even though headset mode is active.

Changes: The playback device can be specified together with the multicast address. It is also possible to specify how multicast are handled even when the user is in an active call. So it is e.g. possible to define a multicast that is used for emergency announcements. For configuration options consult our wiki. Changes
