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 ?

Kind Regards,

Angelo

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 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

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).
