[Asterisk-Dev] Pickup problem with SIP

[Leon Yeh]

Hi Vangelis,

I think you got the older version of the bristuff, try to use latest 
version( bristuffed -0.2.0- RC8).

It compiled and worked well on my FC2 box. I have added additional code 
for steal to only steal if the channel was put on hold only. Let me know 
  if you need additional help.
