I have a pair of opensips stateful proxies and am trying to achieve
Active-Passive failover model with clusterer dialog replication.
Primary Proxy is working in the middle of 2 SBCs and all nodes are
within the same network so NATing is NOT involved ;secondary proxy is
accessible through VPN. It's pretty simple configuration, proxy is
just adding and removing headers in the middle.
So if I stop the opensips service on primary IP , SBCs blacklist that
and start sending new invites to secondary IP that takes active state.
That's all good.
But if I reproduce this failover during a connected session , SBCs do
not send mid-dialog requests/responses to failover IP. I can see they
still try to send messages to primary SBC which obviously end up with
timeout. I understand the most natural solution is HA with Virual IP
but it's not possible because secondary IP is accessible through VPN.
I tried to use DNS SRV record with priorities but that also does not
work with mid-dialog messages, I also have tried to change
record-route/via header to fqdn through advertise_address. Its not
changing record-route but via only but I am still not getting expected
results.
Any guidance of possible solution(s) here will be appreciated.
