Opensips3.0 Highly Availability of progress call?

[amitpaltech]

Hello guys,
hope all of you are fine.

My primarily requirement is to recover the Progress call(Ring) in failover between two opensips vm.
I am new to opensips previously I was working with freeswitch which is not provide the same.
By my understanding with opensips this can be achieved by two node HA in clustered environment.
I have done clustering configuration on both server , please find the attached configuration file of both node.

when I shift the floating IP (keepalived) during progress call following error are received on current control server

can you suggest me what is missing by me , what is required to done to achieve this requirement.

pls find attached opensips configuration script for both node.

@amitpaltech , OpenSIPS does not replicate transaction state or dialogs before being answered. The dialog replication starts only after the call is established.

Dear bogdan,
Thanks bogadan for your kind response.
is any other way to achieve my requirement with opensips? I want to recover Ringing call while floating IP move to another opensips instance. is the opensips have the capability to achieve this?
please reply me asap. I am waiting for your response.

[bogdan-iancu]

no, this is not possible

[amitpaltech]

no, this is not possible
Hi,
Can you suggest an alternate mechanism to achieve replication of transaction state. Can you guide how it can be achieved in OpneSip or is there a mechanism to get commercial support to achieve the desired objective. Do you think it can be achieved using Kamillio. I have a customer who wants high availability for ringing calls and calls that in process of being set up.
