Snom programmable buttons


I want to pick up a call with the snom’s programmable buttons with asterisk server (v 1.2.0), I tried with the option ‘Destination’ and when the incoming call arrive to another snom phone the button blinking.
In this way I can only pick down it pressing the blinking button.

The solution is call the *8 or parcking the call but my pbroblem is when the incoming call are 2 or 3 and I would press a programmable button to pick up the calls.

Are there solutions ?

Thanks L.L. [cfh]
