Hi Daniel,
Thanks for you reply , Yes we indeed do use powerful hardware configuration server ,and we would tune to (centos) OS limits. There are many good blogs available on kamailio for high throughput and performance, we refer the same . One of them is https://github.com/kamailio/kamailio/blob/master/doc/tutorials/tcp_tunning.t...
Thanks again. Warm Regards Pintu

Hello,
there were companies that pushed hundred thousands of active tls connections to same kamailio and it went fine. You will have to do some tuning to kamailio params as well as to the operating system limits, but if you have powerful hardware, having such number of active tls connections should be fine.

Hi Yasin, Not yet tested, My bad - it's 0.1 million with TLS but yes we are yet to test ), We need to distribute the users to different Kamailio cluster through API server. However, Would like to try Option 2 as well and test with it.

Hello Pintu
1 million TLS user? Have u ever test with tester on Kamailio ?Because I remembered in sr-mails that an user tested on 1000 client on TLS transport , it consumes so much CPU etc . I guess 1 milliyonTLSUser make big impact your system for all registration/call.
I tested option-2 for relaying registers about 1-2 years ago for proof of concept. It works fine.
you can replicate user location data by Dmq_usrloc module and can use path header then build a triangle topology to bridge calls. Or You can build a Location Information service to find which kamailio has UAC data .
Best Regards.

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 :
- We use FCM and APNS push to wake up the app.
- Multi forking / Late forking cases are also involved.
- 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

Hi Everyone,
Which one among the below option is highly recommended for setting up Kamailio (for production)
- Kamailio behind NAT *or*
- 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 :
- We use TLS
- Using coturn for media
Thanks Pintu
