In theory, you could use a FWM (firewall mark) setup and persistent  
connections.  If you map the virtual server group to use the same FWM  
for the TCP ( SIP uses TCP port 5060) and UDP (RTP usually is  
configured for UDP ports 16384-32767)  datastreams.  It should work in  

However, the application-based Load-balancing in Asterisk does  
function fairly well and you might end up with a better solution.   
Typically, with load-balancing I find that the more complexity you add  
just makes it that much harder to debug when things go awry.
