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.

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.

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 Yasin CANER ________________________________ From: sr-users <[email protected]<mailto:[email protected]>> on behalf of Pintu Lohar <[email protected]<mailto:[email protected]>> Sent: Tuesday, February 26, 2019 8:09 AM To: [email protected]<mailto:[email protected]> 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 Pintu
