Nway confernece call finally works

Asterisk 1.4.4

Followed the link voip-info.org/wiki/view/Aste … call+HOWTO, after 1 week struggling, finally, the nway confernce call is working, but I have to change some conf in extensions.con.

1st, FindFreeConf is not registered function, I have to manany assign the conference number xxxx.

2nd, dial plan
exten => 0,n,Dial(Local/${DEST}@dynamic-nway-dest,g) dose not work properly, if you only Asterisk is SIP only, just simply replace above dial plan to :
exten => 0,n,Dial(SIP/${DEST}).

Anyway it is working, I wonder what features I am going to lost after these 2 change.
