1. It would be a nice feature, if the speed-dial key would blink or light up, when a call from the assigned number comes in.2. the speed-dial-keys should be also assignable with more functions like call-forwarding,... The LED could light up, when the function is active. I am a user of the GXP-2010 WITHOUT Asterisk or any PBX-System. So it would be nice, if the dual-color-LEDs would show some information ;-)
