Uhhhh.... Yeah. What did you think was going to happen, Asterisk was 
going to magically bridge four phones together because they all answered?

As soon as one phone answers, the call is complete and the remaining 
phones will not be able to answer (because the calls going out to them 
will have been destroyed).

If you need more than two parties in a call, you need to use MeetMe or 
one of the other conferencing applications.
