Is 223 a registered alias of 827?
Have you configured this destination pattern in 827?

 From http://www.packetizer.com/in/q24.html

resourceUnavailable
-------------------
Indicates that the gatekeeper does not have the resources, such as 
memory or administrated capacity, to permit the call. Could possibly 
also be used in reference to the remote endpoint, although another 
reason may be more appropriate, such as callCapacityExceeded.

asterisk-oh323 cannot handle G.729 properly yet. Try it with G.711.
Make sure that cisco also uses the same codec. You should also
set the 'frames' option, in oh323.conf, to the same value used by
the cisco gw.
