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?
Kind Regards,
Angelo

opensips documentation.

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 ?

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

Hello,
We are thinking to use kamailio to fully support our current voip
service.
[snip] What would be the best kamailio
module and topology as solution to this requirement?
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).
With best regards,
