BLF with Star Code function

[mwb12345]

How do we get it to ignore the idle state and still pass the FULL *852113 ?? That is EXACTLY what we need it to do. In these shared line applications the customer would never press the BLF button while the Call is ringing. They would answer the call and then press the BLF key where we would need the phone to send the *85 and extension number which will put the call in park and blink the LEDs on all the phones sharing registration. Than anyone can push the programmed button to pick up the call and we have Shared Line Appearance.
