Considerations
• If several calls arrive at a DSS/BLF key, the calls are queued and ring on a first-in, first-out basis.
• If a BLF key has a second call while busy and off- hook signalling is enabled, the BLF key starts
blinking. The call can be answered by pressing the BLF key or going on hook and then off hook.
DIL Appearances
DIL keys are used to originate and receive calls over specific trunk numbers (DIL keys can be
assigned to any trunk number).
The LED for a DIL key will flash red on an incoming call even if the trunk is set to ring. If another
extension answers the call, the LED on the telephone will light solid red.
