Hi there,
If you use DNS server for load balancing... the client receives one of your domain IP
addresses according to SRV. I don't see the problem with a call here, cause UAC asks
the address only once (before sending INVITE). UAC already has the IP for BYE/reINVITEs.
So why would you replicate INVITEs?
If you use IPVS/LVS... I believe you can force SER to insert it's public IP into VIA,
so there is no problem with replies. With regard to another requests, I believe load
balancer keeps connection template, then when another request comes it would be forwarded
to the same ser.
Any comments?

Yes, I believe that is so. But still you get a problem if the NAT is
restricted, port-restricted or symmetric... The best would be to load
balance and always make sure that a given client is handled through a given
SER (REGISTER and INVITEs). That includes forwarding INVITEs from one SER to
another... OR you must load balance in front of your servers with one common
public IP.

Ack, I didn't even think about NAT. Would these be
added before it
gets sent off to the second proxy? ie:
if (!src_ip==blah.netlogic.net) {
add_rcv_param();
t_replicate("blah.netlogic.net", "999");
};

Well, you still have the NAT issues unless you do load balancing and
your
SER servers have the same public IP.
Have you looked at 0.9.0 nathelper function add_rcv_param() ? It will
add received info to the contact header for the other SER to
process. Haven't really tried yet...

I'm starting to lean this direction, using
t_replicate and all. I
could never get usrloc (db mode) to function properly.. t_replicate
