      <div dir="ltr">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.
        <div><br>
        </div>
        <div>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.</div>
        <div><br>
        </div>
        <div>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.</div>
        <div><br>
        </div>
        <div>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.</div>
        <div><br>
          Any guidance of possible solution(s) here will be appreciated.</div>
