asterisk users - Aug 2004 - h.323 debug

I've got a problem connecting to Cisco call manager.

  h.323 debug shows this 

Allowed Codecs:
         Table:

 Set:
   0:
     0:
       G.711-ALaw-64k{sw} <1>

        == New H.323 Connection created.
        -- 6129 is calling host 3200@10.1.105.3
        -- Call token is ip$localhost/7984
        -- Call reference is 7984
        =*= In CreateRealTimeLogicalChannel for call 7984
                -- externalIpAddress: 10.23.17.5
                -- externalPort: 11972
