I have a customer who has just started operating a dialer. Over the
past couple of days this dialer has been creating some minor issues with
our US48 termination. We are currently running Server:: Kamailio
(1.5.1-notls (x86_64/linux)).
I would like to limit on a subscriber by subscriber basis the amount of
outgoing calls per second that they can do. I am reading through the
ratelimit module documentation, but haven't been able to determine if I
can use it to limit one particular subscriber outgoing activity. I have
also looked at the pike module, and think that I may be able to use it
in order to limit calls per second by IP. Does anyone have any
recommendations, suggestions, or examples that can be used to control
the calls per second based on the kamailio subscriber name.

The ratelimit module will do the job here. It was designed for
something like that.
You will need to define a pipe with the desired cps and then run all
the incoming INVITEs from that specific subscriber through your pipe:

Does the call to rl_check_pipe add the invite to the pipe, and update
the counters before returning. Also would I need to define multiple
pipes for multiple subscribers who I wish to rate limit? ie. The cps
from subscriber A does not affect the cps from subscriber B

Define a pipe for each subscriber that you want to limit. Each pipe
will have it's one settings.
Keep in mind that there is a limitation (only 16 pipes):
http://kamailio.org/docs/modules/1.5.x/ratelimit.html#id2506247
If you want more then 16 pipes, you will need to modify the code and recompile.
In upcoming 3.1 there will be a pipelimit module that will get rid of
the above limitation.

Hi Stagg,
another idea to throttle specific/ all customers to a certain load would be to
use the dialog profiles functionality. This would allows you to limit
concurrent dialogs, albeit its more heavywight (on CPU and RAM terms) then the
mentioned modules.
An example (taken from an old mail), limit to two concurrent calls per user:
modparam("dialog","profiles_with_value","caller")
....
/* do some checking */
get_dialog_size("caller","$fu","$avp(cnt)");
if ( $avp(cnt) > 2 ) {
sl_send_reply("403","Not allowed");
exit;
}
set_dlg_profile("caller","$fu");
/* route the call */
Cheers,
Henning

With dialers, it's the cps that is causing issues (the calls are very short).
Actually, both cps and channel limitation can be implemented
simultaneously (via ratelimit and dialog module).
The burden on the server is not high even at high cps (>150cps) with
channel limitation in place (i.e. dialog profiling enabled).

Hi Ovidiu,
you're right. I had in my mind more fraud traffic patterns, where you too have
many short calls, but they're setup also concurrently.
