Hi Yasin,
Thanks indeed for your valuable input for the
active-active cluster(Option-1) & Option-2
We definitely would like to try setting up an active-active cluster for the
next phase if not in current phase.
But In order to use Kamailio in the active-active cluster, I think we
need to forward or replicate registration to both the active-active server?
in order to proxy the invite packet through the server where the UA is
registered?
We use the following use cases :
1. We use FCM and APNS push to wake up the app.
2. Multi forking / Late forking cases are also involved.
3. Using Kamailio as a stateful proxy.
Thanks & Regards
Pintu

Hello,
My suggestion is that stay away from NAT if you dont have to. various sip
client/Firewalls make out troubles for registration and invites, even if
Kamailio can handle it. If you have a high load TLS connection /
subscriber , I think you should use load balancer and NAT options.
For example;
1 - Load balancer like F5 that balancing your connection active-active
Kamailios
UAC ----> F5 ------> Kamailio -1 (advertises public IP)
|
-------> Kamailio -2 (advertises public IP)
2- Use kamailio as MultiHomed that convert transport layer to tcp/udp
UAC ---------> Kamailio(TLS-PUBLIC IP-mhomed) -------> Kamailio-1(TCP/UDP)
|
---------> Kamailio-2(TCP/UDP)
Good luck

*Subject:* [SR-Users] Kamailio behind NAT or With Public IP - Which one
is highly recommended
Hi Everyone,
Which one among the below option is highly recommended for setting up
Kamailio (for production)
1. Kamailio behind NAT *or*
2. Setting up Kamailio using public IP?
are there any disadvantages if we setup Kamailio behind NAT and use
advertise option in listen parameters?
We have tested both the options, and both the options work great for us(
a. Kamailio behind NAT with advertising in listen parameters b.Kamailio
setup with public IP). So wondering which one is best and highly
recommended?
Some extra info :
1. We use TLS
2. Using coturn for media
Thanks
