To switch calls from one server to another you have to use redis and
rptengine using HA with pacemaker y corosync.
You must have two OpenSIPs, Two RTPEngine, Two Redis servers
(primary-replica) Two Mariad servers (primary/primary)
With redis you can save calls data (ip, ports, callid) on active server
and then use these data on the replica server when swithc to active. On
my tests, when switching from a server to another I have between 5 and
10 seconds without audio.

I’m not using a VIP and I have made some progress by setting a different active tag on each
node…then upon node failure setting the failed node's tag to active on remaining node. This
lets the re-invite pinging work, etc. It’s almost there but the handling of the BYE…they are
still sent to the IP of the failed node even after re-invite pings so any in-progress calls
from the failed node are zombie when they hang up until the re-invite ping times out (30
seconds). I found an article about initiating a re-invite on the new node with something
like "opensips-cli -x mi dlg_send_sequential
callid="442CB6C1-6005F8B80009DA08-FC731700" mode=challenge body=outbound” but that
either seems to terminate the call immediately or say the dialog wasn’t found.
Thanks,

With dialog writing to db that both servers use. And same tag on both - modparam("dialog",
"dlg_sharing_tag", "vip1=active")
had this working on opensips 2.4
thanks

Hi,
I've been attempting to get a two node active/active setup to work with the
v3.1 clusterer module sharing usrloc and dialog. The setup is fronted by a
proxy that handles all of the NAT/media so either OpenSIPS instance can
communicate directly with the user.
What I have working so far:
Registrations and calls work when sent to either node and if you stop OpenSIPS
on a node new calls work fine using the other node.
What I can’t get to work:
Calls that are already in progress to switch between nodes when one node fails.
I have messed around with various sharing tags…no tag, same tag, different tags
but haven’t had any luck. I’m guessing that I’m missing something to trigger
the remaining node to send re-invites. Has anyone attempted this type of setup
and have any ideas?
Thanks,
Kevin
