I think the delay is so the Toshiba system can proccess the digits before sending them out. If you set the trunks to "Immediate Cut-through" Then you will connect directly to the trunk line. I think the delay may be gone (can't remember), because now it's just sending DTMF without proccessing the digits dialed. No matter what, you have to wait for dailtone from telco before you dial.
Problem is: You Will Lose REDIAL!
I don't know why you would set it for idle. If you pick up the handset, I would think you want either intercom or a line. You can dial a number without pickup up the handset or picking a line. Dial 9 first to call an outside number. Just leave the phone on-hook and just start dialing, as fast as you can.
Speaking of DK; I'm not really a DK person (started on CTX), but I now service them sometimes. Had a guy that dialed so fast after pressing the line key, that the telco would very often miss the first digits. He made many wrong number calls.
