That should work around the issue but will not "fix" it.  Issue is the 
h225 TCP session is getting aborted by TCP FIN or RST.  Allowing h.323 
call preservation will mask the issue by allowing calls to stay up.  
However, there will be no supplementary services for those calls such as 
hold/transfer.  Call will be in the same status as when a call is active 
and phone changes to "cm down, features disabled".

Additionally, preserving h.323 calls is likely to leave abandoned active 
RTP session active between endpoints in the network.  Calls can be 
nailed up indefinitely until endpoints are rebooted or calls forcibly 
cleared.  If the call goes out a gateway on remote site as an LD call 
to, for example, a conference service, you could run up one whopping 
phone bill.  When call is "preserved" CM gives up on all management of 
the call so even CM's "max call duration" does not tear the call down 
after 24 hours.
