Administrator’s Guide for SIP-T2 Series/T4 Series/T5 Series IP Phones188Macro ActionDescription$LEDtime>&L(not applicable to T19(P) E2 IPphones)The status of the BLF/BLF list DSS key LED. Enable tospecify the LED color for the BLF/BLF list DSS key, andspecify the duration time (in milliseconds) for thecorresponding status of the BLF/BLF list DSS key. The validvalue of the duration time ranges from 100 to 60000ms.Can be composed of multiple combination of “color” and“time”. The status will be stuck in an infinite loopuntiltriggered by other macros.Supported colors include (must be lowercase):r (red)ri (red; red with incoming mark for T48S/G)ro (red; red with outgoing mark for T48S/G)g (green)gi (green; green with incoming mark for T48S/G)go (green; green with outgoing mark for T48S/G)o (off)&L(Optional.): You have to put the “&L”last in the command flow.Example:$LEDg1000o100r300&Lidle$ means an infiniteloop for BLF/BLF list DSS key LED status: glow green for1000ms, be in the off state for 100ms and then glow redfor 300ms. At the same time, the label of the BLF/BLF listDSSkey is changed to “idle”.Note: The last “color” can be configured without “time”,and it means permanently displaying the last color untiltriggered by other macros. This macro can be only usedfor BLF/BLF list feature. For more information, refer toBLF/BLF List Key LED Status and Behavior Configuration.EDK ConfigurationTo configure EDK list, EDK prompt, EDK soft keys and custom DSS keys, you have to enable EDK feature.By default, the EDK feature is disabled.Yealink IP phones support displaying the softkey ID or menu item ID by long pressing the Volume Up key.It is especially useful for those users who need to view the softkey ID or menu item ID when configuringEDK macros.The following graphic shows an example for displaying the softkey ID and menu item ID after accessingthe menu of T46S/G IP phones:
