Hi Alex,
Thanks for your help.
I think t_replicate is the best option for me.
I expect about 300,000 to 400,000 end points and maybe 10% of them will
send simultanoues requests per second, so will one instance still be
enough?
And what is the ratio between shared memory and available RAM if my machine
is only dedicated to kamailio?
Thanks again for your quick and direct responses.

Is there any other way other than t_suspend/t_continue that I can use to

Well, one factor is that Kamailio is very high-performant and scales very
well in just one instance. Just how many clients do you have registered and
how many messages per second do you want to process? Unless you're building
an astronomically high-volume, national-scale service and realistically
expect to have millions of endpoints, one Kamailio instance should probably
be fine.
Failing that, there are a variety of ways to push messages to other
Kamailio instances. The easiest generic way to send a message is using a
synthetic request through uac_req_send():
http://kamailio.org/docs/modules/4.2.x/modules/uac.
html#uac.f.uac_req_send()
You can receive it (and the arbitrary payload you have put in it) on the
other server and do something with it.
You can also replicate requests using TM, if appropriate:
http://kamailio.org/docs/modules/4.2.x/modules/tm.html#tm.f.t_replicate
Also, some modules have started to use DMQ for distributing state:
