I am using Nu Fone Network's h323 drivers.
I can place H323 calls using following in extensions.conf file,
exten => _1732.,1,Dial(H323/${EXTEN}@192.168.1.2)
If I need to use h323.conf to do the same I cannot configure h323 to do the 
same. I get everyone is busy message and I do not see IP packets being 
generated by * trying to communicate to 192.168.1.2. Can someone point out 
what I am doing wrong here.
extensions.conf
-----------------------
exten => _1732.,1,Dial(H323/${EXTEN}@h323-out)
h323.conf
--------------
[h323-out]
type=h323
host=192.168.1.2
In addition in the * console, when I issue following command I do not see 
anything. Is there something that need to be done with codec registration 
for asterisk ?
host01*CLI> h.323 show codecs
host01*CLI>
In addition I see following H323 related messages during asterisk start in 
the Console.
