it depends where you use TCP. Between proxy and gateways IMO it is ok. 
But between clients and proxy it is IMO a problem. E.g. client REGISTERs 
with TCP. For some reason the TCP connection terminates. Then,during an 
incoming call openser tries to make a new TCP connection which will fail 
as user is behind NAT. Depending on the TCP timers this will block the 
thread.
