Hello,
We are thinking to use kamailio to fully support our current voip service. I would like to know what is the best practice to use kamailio for several thousands for clients that connect to us via TLS. We would like to have a front "cluster" to be able to handle all these connections in balanced way. All clients register to us and the do calls that we statefully forward to the provider. On our test we have already created a single kamailio that successfully accepts and handles registration, do the control and routing to next provider with dispatcher and also do the accounting with cdrs. We want to separate this controlling, routing, accounting and dispatching from the front end and create a front "cluster" to offload the TLS and also be redundant to as many connections by adding more kamailio's. What would be the best kamailio module and topology as solution to this requirement?
Thank you in advance.
Kind Regards, Angelo

When designing a Kamailio deployment for several thousand plus clients, there are many factors to consider... including network topology, future growth plans, high availability, redundancy, etc.
The quick answer top your question is: It depends.
There are many discussions and presentations made over the years including some posted to the kamailioworld youtube channel (youtube,com/c/kamailioworld) as well as slides regarding large scale deployments (such as 1&1).

Hi Fred,
Thanks for the suggestions. I have been looking to all these presentations mostly from Rasvan but, he mostly suggesting clusterer module combined with anycast which I cannot locate on current version 5.x. Can you help me on what is the replacement for this?

I thinking about using glb-director as a front-end load balancer for a set of Kamailio servers. This allows the use of one IP address for all Kamailio servers (like anycast) in different data centers. And use the same IP address for RTP traffic.
If you want, I can help you configure the test-bed of this approach.

Hello Angelo,
it is possible to use Kamailio with an anycast setup, there are two talks in the last years KamailioWorld conference about more details.
But if we are only talking about several thousand clients, it’s not needed for a start. Its certainly possible to operate this just with one front-end Kamailio in an activate/passive setup, many people do this. E.g., look to this (rather old) performance tests, 1.000.000 contacts with TLS on one server http://sip-router.org/wiki/performance/v3.0-capacity
Kamailio has no cluster module, you probably want to investigate the DMQ module which offers clustering capabilities.
Cheers,
Henning

HI,
Thanks for all the suggestions. I will look into glb-director and I will come back in case I need more help. As I understand for same DC and two Kamailio's on active/standby with keepalived is fine, at least for the load we are expecting now.
Now one question on DMQ. Up today with the one only Kamailio we are using the dialog db_mode 1 to have all dialogs in db, in order not to loose the dialogs in case of reload. When we will have 2 Kamailio's with DMQ sync for all dialogs, in case of one Kamailios reloads it will get all active dialogs from the other Kamailio without the need to have the DB to handle this and also delay the system. Is this the correct approach?
Last, do you know any updated doc for Anycast - Kamailio like the one here for the older version 2.4 ? https://blog.opensips.org/2018/03/21/full-anycast-support-in-opensips-2-4/

Sorry Fred,
I believe, my question was wrongly asked. The correct question would be, Is there a guide for Kamailio and Anycast that anyone could point me to read?
But, my main question is about the DMQ on two Kamailio nodes and what happens in case one of them reloads. Are the dialogs and useloc synced automatically on reload? Is there a template config to read about this?

Hi,
we did some testing with ipvs but unfortunately where not been able to pursue it further. Today we use NAPTR/SRV Records for balancing to several TCP Loadbalancers.

Hi Fred,
Thanks for the suggestions.
I have been looking to all these presentations mostly from Rasvan but, he mostly suggesting clusterer module combined with anycast which I cannot locate on current version 5.x. Can you help me on what is the replacement for this?
Kind Regards,
Angelo

The quick answer top your question is: It depends.
There are many discussions and presentations made over the years including some posted to the kamailioworld youtube channel (youtube,com/c/kamailioworld) as well as slides regarding large scale deployments (such as 1&1).

Hello,
for the records, there is a minimal config example in the repo:
* https://github.com/kamailio/kamailio/blob/master/misc/examples/mixed/kamaili...
Maybe it is useful for a starting point, although I think it targets use of UDP.
Cheers, Daniel

Thank you all for the suggestions!. I will look into them. As we have the UAs connecting with TLS I can understand that there are many issues to handle on an unexpected shutdown of a kamailio server and keep the TLS sessions alive.
