Hi Tuomas,
In your script, I would try to handle the case when a back server (a
destination in dispatcher) is down and re-route to the other available
destination - use failure route with the ds_next_dst() in order to do
serial forking in case of failure.

register my client with the SIP domain as the IP address of the
dispatching OpenSIPs server as the SIP proxy on the client, the
registration request times out. I do NOT see the destination OpenSIPs

I see in tcpdump the client's register is received, then the

packets Source IP is marked as 192.168.1.1 -- which is NOT the

dispatcher will overwrite the source IP with 192.168.1.1 -- is there
a configuration that I should have to make it use its advertised_address?

Re: [OpenSIPS-Users] Load Balancer module for REGISTER as well as INVITE?
Yes, I really wanted to use variables for doing the forwarding, but that method only accepts literal strings, so I had to do this in m4 script. Really crude as you say. We're looking into doing the simple active-standby failover first. Doing scalable Client NAT traversable, RTP Proxying, shared database solution is a long stretch.

Re: [OpenSIPS-Users] Load Balancer module for REGISTER as well as INVITE?
Load balancer depends on SIP address only for routing, so just about any SIP server and just about any SIP method, you can use this module for load balancing. However, you need to plan carefully how on-net calls and presence will work in such an architecture! Thank you.

[OpenSIPS-Users] Load Balancer module for REGISTER as well as INVITE?
Can the Load Balancer module be configured to balance REGISTERs as well as the INVITES so that the above mentioned setup would work? OR is the Load Balancer module just useful for balancing RTP Proxy / media server resources for INVITEs? I'm new to the Load Balancer module of OpenSIPs. I am running OpenSIPs stable branch 1.7 - just by looking examples from the documentation it looks like INVITE load balancing is supported.
