    Tried this with the Stable 1.0.6 connected to Panasonic D500 and it 
indeed hung up a call from panasonics EXT  or CO line but it doesn't give a 
busy or concestion signal to a caller (no sound to caller). I presume this 
is a Panasonic issue :( .

    I belive that I have tried to set priindication=outofband and then tried 
with Congestion() in dialplan but it had a same effect as setting PRI_CAUSE 
+ Hangup() . I'll try with the priindication=oob tomorow and i'll post 
results if there is any success.
